Anyone who is gluten free knows how hard it is to find baked goods that avoid the dry, crumbly texture that gluten free treats often have. When I was diagnosed with celiac disease many years back, I made it my mission to recreate recipes that we know and love without compromising on flavor or texture. These homemade peppermint brownies do just that!

Just like my lunch lady brownies and my classic gluten free brownies, these peppermint brownies are dense, gooey, and have just the right balance between cake and fudge, so you get that indulgent bite, every bite.

Ingredients for peppermint brownies (with substitutions)

Flour - This recipe uses a combination of all purpose gluten free flour and almond flour. Giving the perfect consistency with a slightly nutty flavor.
Sugar - A mix of powdered sugar and white sugar is crucial for the ideal sweetness and texture
Eggs - Binds everything together well.
Butter - Adds moisture and richness to the brownie batter and the chocolate frosting. Swap for vegan butter for a dairy free option or try my gluten free dairy free brownies.
Cocoa Powder - For an especially deep chocolate flavor, I like using especially dark cocoa powder, but regular cocoa powder will work just fine.
Peppermint Oil - Adds a refreshing peppermint kick, balancing the richness of the chocolate.
Milk - Used to help smooth the filling. Dairy-free milk can be used as a substitute.
Other baking basics - Salt, xanthan gum, baking powder, etc.

What type of gluten free flour works best?

For the best brownies, I recommend a high-quality gluten free flour that has xanthan gum for the right texture. My top choice is King Arthur Gluten-Free Flour. It offers a delicious consistency and flavor. Almond flour is also popular in baking because it gives that classic brownie texture with a slight crispness.

How to make gluten free peppermint brownies

Prepare: Preheat the oven to 350°F and grease an 8x8-inch baking pan.

Cream the Base: In a stand mixer, combine the sugar and coconut oil, then incorporate the eggs one at a time.

Dry Ingredients: In a separate bowl, mix gluten-free all-purpose flour, almond flour, xanthan gum, salt, and cocoa powder.

Mix the Batter: Gradually add the dry ingredients to the creamed mixture, stirring until well combined.

Bake: Pour the batter into the prepared baking pan and bake until the edges are set and a toothpick comes out clean.

Prepare the Filling: While the brownies cool, make the peppermint filling by mixing together the powdered sugar, softened butter, milk, and peppermint oil until creamy.

Layer the Filling: Evenly spread the peppermint filling over the cooled brownies and refrigerate for a few minutes.

Finish the Brownies: Top the frosting with peppermint chocolate layer. Chill the brownies thoroughly before slicing into squares.

Is there a substitute for almond flour?

Yes, you can swap out the almond flour with an equal amount of gluten-free all-purpose flour. However, almond flour helps give the brownies a slightly nuttier flavor and moist texture, so if you have it on hand, I recommend keeping it in the recipe.

Storing and Making Ahead

Storing: To keep these brownies fresh, store them in an airtight container in the refrigerator for up to 3 days. Reheat them in the microwave or enjoy cold!

Freezing: These brownies also freeze well. Simply wrap individual squares in parchment paper, then store them in an airtight container for up to 3 months.
