How to Make Vegan Gluten Free Oatmeal Cream Pies
Make the Oatmeal Cookies
To start, preheat the oven to 350 degrees. If desired, for easy clean up, line a cookie sheet with parchment paper otherwise use a non-stick cookie sheet. Then, mix the water with the flax seed to make a flax egg and set aside.
Then, in a stand mixer using the paddle attachment or with a hand mixer and large bowl, combine the brown sugar, sugar and plant-based butter. Mix until light and fluffy scraping down the bowl as needed to make sure it is evenly combined.
Next, add the wet ingredients: flax egg and vanilla extract. Mix to combine. Add the remaining dry ingredients: gluten-free oats, gluten-free flour, baking soda and salt. Mix until well combined.
Scoop cookie dough by tablespoon sized scoops and place on baking sheet, about 12-15 per baking sheet. We like to use a small cookie scoop to keep smaller cookies a uniform size. Slightly press down on the tops of the cookies since they won’t spread much on their own. Bake in a preheated oven at 350 degrees for about 12 minutes or until slightly golden brown. Remove from the oven let cool for 2 minutes then transfer to a wire rack to cool completely.
These gluten free oatmeal cookies can also be enjoyed on their own without a creamy filling.
Make the Vegan Buttercream Filling
In a stand mixer with the paddle attachment or with a hand mixer, beat the plant-based butter on medium speed until softened and lighter in color. Then, add the powdered sugar and mix until combined. Add vanilla extract, water and salt and mix until combined. If the buttercream is not fluffy simply turn up the speed on the mixer for 2-3 minutes and let it whip. This vegan frosting recipe is also great for cupcakes and cakes.
Assembling Oatmeal Cream Pies
The best way and quickest way to assemble these cookie sandwiches is to use a piping bag but it is not necessary. If using a piping bag, add buttercream to a piping bag and cut a small tip at the end. If not using a piping bag simply use a knife to add a dollop of vegan buttercream to the cookies.
Then, once cookies are completely cool, pipe a circle of buttercream on the bottom of half of the cookies. Then, top the buttercream with another oatmeal cookie. Press slightly to spread buttercream to the edge and to keep cookies sticking together.
How to Store Oatmeal Cream Pies
These Vegan Gluten Free Oatmeal Cream Pies are best stored in an airtight container for up to 5 days. They can be stored at room temperature or in the refrigerator.
Frequently Asked Questions
Absolutely! Be sure to press the dough balls down as they will not spread in the oven when baking. The baking time may also need to be adjusted to account for a larger amount of dough.
We tested this recipe with a gluten free flour blend containing xanthan gum. While I think this recipe will work okay with oat flour I can’t promise the results. If you do try it please let us know how it turns out. For best results, use a gluten free flour blend containing xanthan gum such as King Arthur Gluten Free Flour.
Yes! This recipe originally used regular flour and oats instead of gluten-free ingredients. Go ahead and substitute regular oats and all purpose flour in the same amounts. Keep the flax egg and plant-based butter for vegan oatmeal cream pies.
