Why We Adore This Oatmeal Cream Pie Recipe
There’s something truly special about a homemade version of a beloved classic. Our Oatmeal Cream Pie recipe isn’t just about mimicking a store-bought snack; it’s about elevating it. We adore this recipe because it yields cookies that are incredibly soft, with a rich molasses and spice flavour that perfectly complements the sweet, airy cream filling. Unlike some commercial versions that can be a bit dry or overly sweet, our homemade oatmeal cream pies strike the perfect balance. Plus, baking them yourself means you know exactly what ingredients are going in – no mysterious additives or preservatives. The scent that permeates your kitchen as these cookies bake is pure, comforting nostalgia. It’s a fun baking project that results in a truly irresistible oatmeal sandwich cookie.
What Makes the Perfect Oatmeal Cream Pie?
Before we dive into our Oatmeal Cream Pie recipe, let’s break down the elements that make this treat so iconic:
- The Cookies: They must be exceptionally soft and chewy, not crisp. A good oatmeal cookie for this purpose has a slightly yielding texture that melts in your mouth. The taste profile frequently features warm spices such as cinnamon and a touch of molasses for richness.
- The Filling: The classic filling is a light, fluffy, and sweet marshmallow-based cream. It should be smooth, firm enough to maintain its form, yet still wonderfully soft.
- The Balance: The sweetness of the filling needs to be balanced by the wholesome, slightly spiced flavour of the oatmeal cookies. The textures should also complement each other perfectly.
Our recipe is carefully crafted to deliver on all these fronts, ensuring a truly authentic and delightful homemade oatmeal cream pie experience.
Essential Ingredients for Your Homemade Oatmeal Cream Pies
To create these nostalgic treats, we’ll need a few key players. Gathering good-quality ingredients is the first step towards baking perfection. Here’s what you’ll need for our Oatmeal Cream Pie recipe:
For the Soft Oatmeal Cookies:
- Unsalted Butter: 1 cup (227g), softened to room temperature. Crucial for texture.
- Dark Brown Sugar: 1 cup (200g), packed. Adds moisture, chewiness, and a rich molasses flavour. Light brown sugar can be used, but dark is preferred for depth.
- Granulated Sugar: ½ cup (100g). For sweetness and structure.
- Large Eggs: 2, at room temperature.
- Vanilla Extract: 1 teaspoon. Enhances all the other flavours.
- Molasses (Treacle): 1 tablespoon (optional, but highly recommended for that classic flavour).
- Plain Flour (All-Purpose Flour): 1 ½ cups (180g).
- Bicarbonate of Soda (Baking Soda): 1 teaspoon. Our leavening agent.
- Ground Cinnamon: 1 teaspoon. A classic spice pairing.
- Ground Ginger: ½ teaspoon (optional, adds a lovely warmth).
- Salt: ½ teaspoon. Balances the sweetness.
- Quick-Cooking Oats (not instant or rolled): 3 cups (270g). Quick oats provide the best texture for these soft cookies.
For the Fluffy Cream Filling:
- Unsalted Butter: ½ cup (113g), softened to room temperature.
- Icing Sugar (Powdered Sugar): 2 cups (240g), sifted.
- Marshmallow Fluff (or Creme): 1 jar (approx. 200-210g or 7-7.5 oz). This is key for the classic light and fluffy texture.
- Vanilla Extract: 1 teaspoon.
- Milk or Cream: 1-2 tablespoons, as needed for consistency.
Choosing Your Oats
For this specific Oatmeal Cream Pie recipe, we strongly recommend using quick-cooking oats. These oats are cut smaller and rolled thinner than traditional rolled oats (old-fashioned oats). This allows them to absorb moisture more readily and results in a softer, more tender cookie, which is exactly what we want for an oatmeal cream pie. Instant oats are too fine and can make the cookies pasty, while traditional rolled oats might make them a bit too chewy or distinct in texture for this particular application.

Step-by-Step Guide to Baking Your Oatmeal Cream Pies
Ready to bake up a batch of these irresistible treats? Follow these instructions carefully, and you’ll soon be enjoying the best homemade Oatmeal Cream Pies ever!
1. Making the Soft Oatmeal Cookies
- Preheat and Prepare: Set your oven to 180°C (160°C Fan / Gas Mark 4). Prepare two large baking trays by lining them with baking parchment or silicone mats.
- Cream Butter and Sugars: In a spacious mixing bowl with an electric mixer, cream the softened unsalted butter with the dark brown sugar and granulated sugar until the mixture is airy and pale. This process generally takes around 2-3 minutes. Remember to pause and clear the sides of the bowl periodically.
- Add Wet Ingredients: Incorporate the eggs individually, ensuring each is fully mixed in before adding the next. Afterwards, blend in the vanilla extract and molasses (if you’re using it).
- Combine Dry Ingredients: In a separate medium bowl, whisk together the plain flour, bicarbonate of soda, ground cinnamon, ground ginger (if using), and salt.
- Mix Wet and Dry: Introduce the dry ingredient blend to the wet mixture bit by bit, using a low mixer speed until everything is barely incorporated. Take care to avoid overmixing at this point.
- Stir in Oats: Carefully fold in the quick-cooking oats until they are uniformly spread through the dough. You’ll find the dough is rather soft and tacky.
- Portion and Bake: Drop rounded tablespoons of the cookie dough (about 1.5 to 2 tablespoons per cookie) onto the prepared baking trays, leaving approximately 2 inches of room between each cookie so they have space to expand. For uniformly sized cookies, a medium cookie scoop works wonders.
- Bake: Bake for a duration of 10-12 minutes, or until the cookie borders are a pale golden hue and the middles have just firmed up. The cookies should still look soft. For truly soft oatmeal cream pies, it’s better to slightly underbake than overbake.
- Cool Cookies: Allow the cookies to rest on their baking trays for 5 minutes post-baking. They will be exceptionally soft. Afterwards, gently move them to a wire rack so they can cool down entirely. Ensuring the cookies are fully cooled before adding the filling is vital.
2. Crafting the Fluffy Cream Filling
- Beat Butter: In a medium-sized bowl with an electric mixer, whip the softened unsalted butter until it achieves a smooth and creamy consistency.
- Add Icing Sugar: Gradually add the sifted icing sugar, mixing on low speed until combined, then increase the speed and beat until light and fluffy.
- Incorporate Marshmallow Fluff: Introduce the marshmallow fluff and vanilla extract into the bowl. Mix on medium speed until thoroughly blended and the concoction is notably light and fluffy.
- Adjust Consistency: If the filling seems too stiff, add milk or cream, one tablespoon at a time, beating until you reach a smooth, spreadable, yet stable consistency. It should be thick enough to pipe or spread without oozing out too much.
3. Assembling Your Oatmeal Cream Pies
- Pair Cookies: Once the oatmeal cookies are completely cool, match them up in pairs of similar size and shape.
- Fill the Cookies: Apply a liberal quantity of the cream filling to the underside of one cookie from each matched set. This can be done with a knife, a small spatula, or a pastry bag equipped with a round nozzle. Typically, 1-2 tablespoons of filling for each pie is ideal.
- Create the Sandwich: Carefully place the flat side of the matching cookie onto the filling, forming your oatmeal sandwich cookie. Avoid applying too much pressure, as this could cause the filling to bulge out excessively.
- Chill (Optional but Recommended): For the best flavour and texture, and to allow the filling to set a bit, we recommend individually wrapping the assembled oatmeal cream pies in cling film and refrigerating them for a minimum of 30 minutes to an hour prior to serving. This also helps the cookies soften further from the moisture in the filling.
Tips and Tricks for the Ultimate Oatmeal Cream Pie Recipe
We want your homemade Oatmeal Cream Pies to be absolutely perfect! Here are a few extra tips we’ve learned along the way:
- Measure Flour Correctly: To measure flour accurately, use a spoon to transfer it into your measuring cup, then sweep a straight edge across the top to level it. Dipping the cup directly into the flour bag can compress the flour, which may result in drier cookies.
- Don’t Overmix the Cookie Dough: Once you add the flour, mix only until it’s just combined. Overmixing develops gluten, which can make your cookies tough rather than soft.
- Use Room Temperature Ingredients: For both the cookies and the filling, using room temperature butter and eggs helps them combine more easily and create a smoother, more uniform result.
- Don’t Overbake the Cookies: This is crucial for achieving that signature soft texture. Pull them from the oven when the edges are set and lightly golden, but the centres still look a little soft. They’ll continue to firm up as they cool.
- Cool Cookies Completely: Attempting to fill warm cookies will result in a melted, messy filling. Patience is key!
- Uniform Cookie Size: Using a cookie scoop helps ensure all your cookies are the same size, which makes for neater, more uniform oatmeal cream pies.
- Marshmallow Fluff is Key: While you can make buttercream-style fillings, marshmallow fluff (or creme) is what gives the filling its classic light, airy, and slightly sticky texture that’s so distinctive in an oatmeal cream pie.
Why Bake Homemade Oatmeal Cream Pies?
You might be wondering if it’s worth the effort when you can buy similar treats. We firmly believe that homemade is best, especially with this Oatmeal Cream Pie recipe!
- Superior Taste and Texture: Homemade versions often have a richer flavour and a much softer, chewier cookie texture. The filling can also be customised to your preferred sweetness.
- Ingredient Control: You know exactly what’s in your cookies. No artificial flavours, colours, or preservatives that you can’t pronounce. You can choose high-quality butter, vanilla, and oats.
- Freshness: There’s nothing like an oatmeal cream pie made with freshly baked cookies and freshly whipped filling.
- The Joy of Baking: It’s a fun and rewarding baking project, perfect for sharing with family and friends. The nostalgic element makes it even more special.
- Customisation: Want to add a hint of nutmeg to your cookies? Or maybe a different extract to your filling? Go for it!

Storing Your Delicious Homemade Oatmeal Cream Pies
Once you’ve assembled your delightful Oatmeal Cream Pies, you’ll want to store them properly to maintain their freshness and soft texture.
- Refrigerate: We suggest keeping your homemade oatmeal cream pies inside an airtight container within the refrigerator. The cold temperature assists in keeping the filling firm while ensuring the cookies stay soft.
- Individual Wrapping: For best results, especially if you plan to pack them in lunches, individually wrap each oatmeal cream pie in cling film prior to putting them into the container. This method stops them from becoming dry or adhering to one another.
- Shelf Life: When stored properly in the fridge, your oatmeal cream pies should stay fresh and delicious for up to 4-5 days. (Though we doubt they’ll last that long!)
- Serving: They are delicious straight from the fridge, or you can let them sit at room temperature for about 10-15 minutes before serving if you prefer them slightly softer.
We generally don’t recommend freezing assembled oatmeal cream pies, as the texture of the cream filling can sometimes change upon thawing. However, you can freeze the baked and cooled oatmeal cookies (unfilled) in an airtight container for more than 3 months. Thaw them at room temperature before making the filling and assembling.
Frequently Asked Questions (FAQ) about our Oatmeal Cream Pie Recipe
Can I use rolled oats instead of quick-cooking oats?
While you can use traditional rolled oats (old-fashioned oats), we highly recommend quick-cooking oats for this Oatmeal Cream Pie recipe. Quick oats create a softer, more tender cookie — exactly the texture you want. Rolled oats will make the cookies chewier and more textured, which may not match the classic cream pie experience.
My cookies turned out crispy instead of soft. What went wrong?
Several things can cause your cookies to be too crisp:
- Overbaking: Pull the cookies from the oven when the centres still look slightly soft — they’ll finish baking on the tray.
- Too much granulated sugar: Brown sugar adds moisture and chewiness. A higher ratio of white sugar can lead to crispier results.
- Too much flour: Mismeasuring flour can dry out your dough. Always spoon and level your flour properly.
Follow the recipe closely and avoid overbaking for soft, chewy results.
Can I make the cream filling without marshmallow fluff?
Marshmallow fluff gives the filling its signature light, airy texture and classic flavour. While you can substitute with a simple buttercream (butter, icing sugar, vanilla, and a splash of milk), it won’t have the same iconic taste. If you go this route, adjust the consistency to keep it stable yet fluffy.
How do I get all my cookies to be the same size?
Use a medium cookie scoop (1.5 to 2 tablespoons). This ensures your cookies are uniform in size, which makes them bake evenly and look more professional, perfect for sandwiching into neat oatmeal cream pies.
Why do my cookies spread too much?
Here are the common causes of excessive spreading:
- Butter too soft or melted: Use softened (not melted) butter.
- Low oven temperature: Make sure your oven is fully preheated.
- Too little flour: Double-check your measurements.
- Greasy baking surface: Use parchment paper or silicone baking mats instead of greasing trays.
Pro tip: Chill the scooped dough on the tray for 15–20 minutes before baking to help reduce spreading.
Can I add other spices to the oatmeal cookies?
Absolutely! Cinnamon is classic, but you can also try nutmeg, ginger, or even a pinch of cardamom for a unique twist. Just don’t overpower the warm oatmeal and creamy filling combo.
Let me know if you want this in HTML format for your website, or if you’d like a table of contents added for easier navigation! Absolutely! While cinnamon and a touch of ginger are classic, feel free to add a pinch of nutmeg, allspice, or even a tiny bit of ground cloves for a different warm spice profile in your homemade sandwich cookie recipe.
