Oatmeal Cream Pie Recipe

Oatmeal cream pies made from scratch have a depth of flavor that the classic packaged version simply cannot match. Raisin paste and dark brown sugar work together to keep the cookies soft, chewy, and full of warm spice in every bite.

These oatmeal cream pies capture all the nostalgia and texture of a Little Debbie treat, but with so much more flavor. Real butter gives these cookies a complexity and richness that oil just can’t deliver. If you grew up loving the original, you’re going to fall head over heels for this homemade version.

Expect a thin, chewy oatmeal cookie with notes of molasses, warm spice, and real butter, sandwiched with a cloud of marshmallow fluff that softens beautifully as it sits. The raisin paste used here makes enough for three batches, so the leftover paste is worth keeping around for stirring into energy bites or these gluten free pumpkin bars.

Ingredients & Substitutions

• Dark Brown Sugar: The higher molasses content in dark brown sugar intensifies the warm spice notes and keeps the cookies soft for days, which matters when they need to hold up around a marshmallow filling. Light brown sugar is the one substitution I condone if that is all you have.
• Unsulfured Molasses: Molasses deepens the chew and gives the cookies their characteristic dark color and rich, almost toffee-like flavor. Unsulfured specifically matters here because the sulfured variety brings a harsh, bitter edge that competes with the spices.
• Raisin Paste: The paste disperses moisture and sweetness evenly throughout the dough, keeping every cookie uniform and soft. The recipe makes enough for three batches, so store the remainder in the refrigerator and use it anywhere you would use date paste, like in energy bites.
• Quick Oats: Quick oats hydrate faster and disperse more evenly than old-fashioned oats, giving a softer, uniform chew without large, tough flakes. Using old-fashioned oats would produce a chewier, rougher texture that does not sandwich as cleanly save those for this carmelita recipe.
• Baking Powder and Baking Soda: Baking powder provides most of the lift, creating a soft and bendable crumb rather than a dense, flat one. The small amount of baking soda works with the molasses and brown sugar to enhance spread and deepen browning.
• Ground Cinnamon and Ground Cloves: Cinnamon is the dominant spice and gives the cookies their classic warm personality. Cloves add depth and a slightly herbal warmth that elevates the flavor, but measure carefully because they are potent and too much will turn medicinal.
• Marshmallow Fluff: Marshmallow fluff creates a sweet, stable filling that mimics the classic cream center without weeping or collapsing. I use original store-bought Marshmallow Fluff because it contains egg whites, just like homemade marshmallow fluff, which gives it the structure to hold up between soft cookies. If you use homemade fluff, do not keep the assembled pies at room temperature for more than 3 days, as it will start to weep before the store-bought version does.

Variations on This Oatmeal Cream Pie

• Change the filling. The marshmallow fluff is doing specific structural work here, so swapping it changes the filling considerably. A Cream Cheese Buttercream Frosting or my [ermine frosting recipe] would be a natural alternative if you want something tangier and more stable for piping, and it pairs well with the warm spice and molasses notes in the cookie. That said, nothing replicates the exact cloud-like chew of the original without the fluff.
• Apple-Filled Oatmeal Cream Pies. The warm spice and molasses notes in these cookies would pair naturally with a thin layer of apple pie filling alongside the marshmallow fluff, similar to what makes this Caramel Apple Tart so satisfying as a fall dessert.
• Add a caramel core! You can pipe a dollop of salted caramel sauce into the center of the cookie!

Professional Tips

• Stop mixing the moment the flour and oats are incorporated. Overworking the dough after the dry ingredients go in develops gluten and produces a tough, dense cookie that does not have the right bend. A few rotations on low speed is all it takes.
• Chill the dough only if your dark brown sugar is especially dark. Heavily molasses-laden brown sugar tends to spread, and a quick 20 to 30-minute chill in the refrigerator corrects that without changing the final texture. For standard dark brown sugar, going straight from bowl to oven is fine, which is what I always do.
• Cool the cookies completely before filling. A warm cookie will melt the marshmallow fluff, causing it to slide rather than hold its position. Patience here is the difference between a clean, professional-looking sandwich and a sticky mess, and the same principle applies anytime you are piping a soft filling, whether it is marshmallow fluff or a Lemon Curd Whipped Cream style filling onto a delicate base.

How to Make Oatmeal Cream Pie

This recipe moves in a clear sequence: raisin paste first, then the cookie dough, then assembly once the cookies have cooled completely. Further details and measurements can be found in the recipe card below.

Step 1: Preheat the oven. Set your oven to 325°F convection (with the fan) or 350°F conventional (without the fan). The convection setting promotes a slightly better spread, which is exactly what you want for a thin, chewy oatmeal cream pie.

Make the Raisin Paste

Step 2: Combine the raisins and water in a small pot, then bring to a boil over medium heat. Turn off the heat, cover the pot, and let the raisins sit for 15 minutes while you measure out the rest of your ingredients, as in sticky toffee pudding. Once they’ve had time to soften and absorb the water, transfer everything, liquid and all, to a blender, a small food processor, or a hand blender, and process until completely smooth. The paste should look like a thick, dark purée with no visible raisin pieces. Set it aside to cool, or spread it onto a parchment-lined baking sheet and refrigerate if you want to speed things up. (photos 1-3 below).

Make Cookie Dough

Step 3: Cream the butter and sugars. In the bowl of a stand mixer fitted with the paddle attachment, or in a large bowl with a hand mixer, beat together the softened butter, dark brown sugar, molasses, and granulated sugar until the mixture is lightened. (photo 4).

The high proportion of brown sugar means you will not get a pale, fluffy cream here, and that is completely normal. What you are looking for is a mixture that has lightened in color and looks something like light brown sugar, a few shades paler than when you started.

Step 4: Add the egg. Add the egg and beat well until fully incorporated. A room temperature egg blends in smoothly and evenly without seizing the butter. If your egg went in cold and the mixture looks slightly curdled, keep beating; it will come together. (photo 5).

Step 5: Add the raisin paste. Add the cooled raisin paste and beat well. The dough will deepen in color and take on a rich, molasses-forward aroma. Make sure the paste is no longer hot before it goes in, or it can begin to melt the butter you just worked to cream. (photo 6).

Step 6: Mix the dry ingredients. In a medium bowl, whisk together the flour, oats, baking powder, baking soda, salt, cinnamon, and cloves until evenly combined. Whisking rather than stirring distributes the leaveners and spices evenly so every cookie bakes the same. (photos 7 & 8).

Step 7: Add the dry ingredients to the dough. Reduce the mixer to low speed and add the dry ingredients in several additions, mixing until just well blended after the last addition. The dough will look dense and slightly sticky, which is correct. Stop mixing the moment everything is incorporated. (photo 9).

I always use softened butter and go straight from the mixer bowl to the oven without chilling the dough. The only time you might want to chill is if your dark brown sugar is very dark, since the extra molasses can push the spread too far. A short rest in the refrigerator will firm the dough back up.

Step 8: Scoop the cookies. Use a large cookie scoop to portion the dough at 54g per cookie and arrange them on parchment-lined baking sheets, leaving enough space for spreading. (photos 10 & 11).

If you want a bite-sized version, portion the dough at 22g per cookie. Bake for 15 minutes, rotating after 7, and you will get about 30 small sandwich cookies.

Bake and Assemble

Step 9: Bake the cookies. Bake at 325°F convection or 350°F conventional for 18 to 19 minutes, rotating the trays top to bottom and front to back after 7 minutes and again at 14 minutes. The cookies are done when the edges are set and lightly golden and the centers still look soft and just barely matte. They will continue to firm as they cool, so pull them at that point rather than waiting for the centers to look fully set. (photo 12).

Step 10: Cool completely. Remove the trays from the oven and transfer to a wire cooling rack. Let the cookies cool completely before filling. They are thin and will feel soft right out of the oven, but they firm into a chewy, slightly crisp-edged cookie as they cool. Do not rush this step, warm cookies will cause the marshmallow filling to slide.

Step 11: Prepare the filling. Scoop the marshmallow fluff into a piping bag and cut the tip off so the opening is about ½ inch across. Use your hand, a bowl scraper, or the edge of the counter to press the fluff down toward the base of the bag before you start piping. If you prefer not to use a piping bag, you can spread the fluff with the back of a spoon or an offset spatula, though the piping bag gives you much better control over the amount and placement.

Step 12: Assemble the pies. Pick up one cooled cookie and turn it over so the flat side faces up and the domed top rests in your palm. Pipe the fluff in a star pattern onto the flat side, leaving a ¼-inch border around the edge. That border matters: keeping the filling away from the edge prevents it from squeezing out under the weight of the top cookie. Press a second cookie flat side down onto the filling, sandwiching the two together. Repeat with the remaining cookies. (photos 13 & 14).
