Stack of Gluten-free Mint Chocolate Brownies


A fudgy gluten-free brownie topped with a layer of mint icing and topped with a smooth layer of dark chocolate… um, yes please.  I’m lamenting the fact that this entire pan of gluten-free mint brownies has been devoured. They were enjoyed by everyone that I shared them with!

Years ago, when I could still eat gluten, a little bakery opened up downtown.  I stopped in, as I LOVE bakeries, and discovered this incredible treat.  The brownies were cut in huge squares and kept chilled.  I would buy one and savor every little bite, usually saving half of it to enjoy the next day since they were so big.  I would crave these brownies every few weeks.

Sadly, the bakery ended up closing.  My craving for these brownies only intensified once I could no longer buy them.  Finally I set to work on figuring out my own recipe for them. 

Gluten-free Mint Brownies and milk

I tried many recipes with less than desirable results like a brownie layer that was too cakey or not chocolatey enough, a mint layer that tasted like toothpaste, and a chocolate layer that wouldn’t look smooth and glossy. 

After many tests and tweaks, and some tips from a friend, I had this recipe perfected.

And then I had to give up gluten. Back to square one. Or maybe not! What if I could take my perfected recipe and just use a good quality gluten-free flour blend in it? Would it turn out the same?

Prior to last week, I had yet to try making them with either of my favorite gluten-free flours (gfJules and Gluten Free Mama). I was confident, though, because they haven’t failed me yet. I can definitely say that these tasted just the same as the gluten-full version I used to make. I’ve now tested it with each of those flour blends with great success!

Thumbs up came from those that have to eat gluten-free and those that don’t!

Layered Gluten-free Mint Chocolate Brownie

A few recipe notes: Since this recipe has multiple layers and they need to cool, feel free to make this over a span of two days. 

I baked the gluten-free brownies one day, then did the mint layer & chocolate layer the next day.

You’ll definitely want to make sure to wait until they are well-chilled before cutting, and you’ll want to keep them chilled when not being served.

Notes on ingredients and substitutions for these gluten-free mint brownies:

  • Use a good quality flour blend. Like I said above, I’ve tested with both gfJules and Gluten Free Mama’s Almond Blend and both worked very well. Other good quality blends like Cup4Cup and King Arthur Measure for Measure should work well too. Just avoid flour blends made of bean flours or only rice flour. I do not recommend using only almond flour or only coconut flour to make these. Those are not a successful straight substitution.
  • Unsweetened chocolate squares: I use Baker’s Unsweetened Chocolate Squares, which are available at all of my local stores or online from Amazon
  • Mint: I tried a number of mint options and I found the best success in using this mint extract from McCormick which you hopefully can  find at your local store, or you can buy on Amazon. I like this one because it is spearmint and peppermint together and gave a better flavor than when I used one or the other alone.

Kept chilled, these stayed nice and moist and tasty for 4 days with no change in quality or flavor. I hope you enjoy them as much as I do!

If you love this chocolate and mint combo, you’ve got to try my other favorite: gluten-free mint chocolate bundt cakes! I make these for holiday parties every December and they’re always a hit!

Prep Time 30 minutes
Cook Time 30 minutes
Additional Time 1 hour 30 minutes
Total Time 2 hours 30 minutes



  • 4 oz. unsweetened chocolate squares
  • 1 cup butter
  • 4 large eggs
  • 2 cups sugar
  • 1/2 tsp. salt
  • 1 tsp. pure vanilla extract
  • 1 cup good gluten-free all-purpose flour *
  • 1/2 tsp. xanthan gum

Mint Layer:

  • ½ cup butter, softened
  • 2 2/3 cup powdered sugar
  • 2 T. water
  • 1 tsp. mint extract
  • green food coloring (I used about 5-6 drops)

Chocolate Icing:

  • 6 Tbsp. butter
  • 1 cup semi-sweet or dark chocolate chips


Brownie Layer:

  1. Melt the unsweetened chocolate and butter in microwave or in saucepan over low heat. Let cool.
  2. In a mixing bowl, beat the 4 eggs until light and frothy, add the sugar and salt; beat well. Fold the chocolate & butter into the egg mixture. Stir in the vanilla, flour, and xanthan gum (if needed). Pour into greased 9x13” pan.
  3. Bake at 350° for 25-30 minutes.

Mint Layer:

  1. Use a hand mixer or standing mixer to beat all ingredients except food coloring together like frosting.
  2. Add drops of green food coloring and mix until you reach the desired color you prefer.
  3. Spread over the cooled brownies.
  4. Place in fridge to set a bit while you prepare chocolate icing.

Chocolate Icing:

  1. Melt the butter and chocolate chips together in a saucepan or in a glass bowl in the microwave, stirring frequently so as not so burn.
  2. Spread over the mint layer.
  3. Chill completely, then cut into squares. These can be cut small as they are rich and flavorful.


*I've tested this with Gluten Free Mama's Almond Flour Blend and gfJules flour. They both work amazingly well.

If using a flour blend that already includes xanthan or guar gum, then omit the xanthan called for in the recipe.

As always, be sure to double-check all of your ingredients to ensure they are gluten-free. You can double this recipe for 11x15” jelly roll size pan.

Is the butter for the brownie layer to be melted or softened?

Hi. Have you ever made these egg free? What would you recommend to replace the 4 eggs? So you think an egg substitute like the egg replacer would work? Thank you.

Would the recipe still turn out if I omitted the xanthan gum? I don't have any on hand, but I still want to try these. Thanks!

If your flour blend doesn't have any gums (xanthan or guar), then your brownie layer will likely fall apart. I would wait to make until you have some!

Can you make ahead and freeze them? Like for a month?
