Tips For Sucess:
- Always ensure your cakes are completely cooled before frosting them.
- You can use any flavor of frosting; I have some great Gluten Free Frosting recipes for you.
- Check my Gluten Free Sprinkles List if you use sprinkles to decorate your cake.
This is one of my favorite gluten-free flour blends for cookies, cakes, pie crust, biscuits, and muffins! (Do not use this flour blend for yeast recipes.)
Ingredient Notes:
- Gluten Free Flour Blend - I have tested two gluten free flour blends in this recipe. I liked King Arthur Gluten Free Measure for Measure and Bob's Red Mill 1 to 1 Gluten Free Flour Blend. This doesn't mean other blends won't work, I just haven't tested any others. Try to avoid flour blends that are high in starch.
- Xanthan Gum - this is the stuff that holds your baked goods together. If your blend does not contain Xanthan Gum, you must add one teaspoon.
- Cocoa Powder - Most cocoa powders are gluten free but always check the ingredients label. I love Rodelle and Anthony's brands of cocoa powders.
- Butter - Use unsalted butter, plant-based butter, or coconut oil.
- Pure Vanilla Extract - do not use imitation vanilla.

Recipe Step-By-Step Directions:

Step 1: Add your dry ingredients to a bowl and whisk to blend. If you are using butter, you will want to melt it.
I recommend using the spoon or leveling method to measure your gluten-free flour.
Put the measuring scoop into the flour and fill. Do not pack the flour. Use a knife to scrape along the top to remove the extra flour.
You can also use a spoon to fill the measuring cup. Use a knife to level along the top to remove the extra flour.
Step 2: Add the wet ingredients to a bowl and whisk to blend.

Step 3: Pour the wet ingredients into the dry ingredients. Mix until the batter is just barely mixed. This will help keep your brownies a bit fluffier for the cake.

Step 4: Mix the gluten free brownie batter well and pour it into greased mini heart cake pans. (Note the pans I used were discontinued, so I found similar pans.)
Step 5: Bake the brownies at 350º F for 20 minutes until done. Remove from the pans onto a cooling rack. When the brownies are cooling, whip up the frosting.

Step 6: Add the frosting ingredients to a standing mixer. Make the white buttercream frosting. Feel free to divide your frosting into two bowls and add red food coloring to one to make a pretty pink frosting as we did.

Step 7: Place the bottom on a dish and add frosting to the top of the cake. Place the next cake layer on top and frost.

What is the best gluten free brownie mix?
If you don't want to make gluten-free brownies from scratch, you can use several delicious gluten-free brownie mix brands to make this brownie layer cake recipe. My favorites are:
- Krusteaz Gluten Free Brownie Mix
- King Arthur Gluten Free Brownie Mix
- Betty Crocker Gluten Free Brownie Mix
Expert Tips and Recipe FAQ:
Yes, gluten-free brownies taste good and are a fantastic texture too. Gluten free brownies differ from brownies made with wheat flour, but they taste just as moist, chocolaty, and delicious.
Gluten free baking is tricky! Wheat is like glue; when you bake gluten-free, getting your baked goods to hold together is a big deal. I use xanthan gum as a binder, but some people can't eat xanthan gum. Guar gum and psyllium husks can also work well as a binder in gluten free baking.
To test for doneness, insert a toothpick into the center of the cake. If the toothpick comes out clean, it is done baking. If you see batter or crumbs, the cake needs to be baked longer.
These cake will keep up to 4 days in an air-tight container or up to 4 months in the freezer.
Yes, you can freeze gluten free brownies. There are a couple of options on how to freeze them. Wrap each piece of cake or brownie individually with plastic wrap. You will want to wrap each on tightly, so no air gets to it. Then place it in an airtight container.
You can also freeze the entire cake using the same method. Either way, consume within four to six months to ensure flavors and textures.

Just made this! Yum!!! A little more gummy than I would have hoped for, but that’s likely the gf flour blend I was using. Will definitely try it again with a different flour blend! So good! I loved that the ingredients are typical ones I always have in my pantry! Thank you!
