These Mint Chocolate Chip Ice Cream Sandwiches are such a fun and easy summer treat. One of my favorite desserts on a hot day is an ice cream sandwich! I love a good, unconventional ice cream sammie though - a cookie or brownie with a thick layer of ice cream sandwiched in between. These aren’t the average ice cream sandwiches with thin spongey wafer cookies from your childhood!

‍

Fudgy, soft homemade brownies, and creamy mint chocolate chip ice cream are combined to create these decadent brownie ice cream sandwiches. For the brownies, I used the recipe from my Baileys Irish Cream Cheesecake Brownies but I swapped the butter for oil instead, so that the brownie layers don’t get rock hard when frozen. You end up with a chewy, chocolatey brownie that is easy to bite into, even after it’s frozen. For the ice cream layer, I went with my all-time favorite, Tillamook Mint Chocolate Chip but you use whatever flavor and brand you love - the possibilities are endless!

How to Make Brownie Ice Cream Sandwiches

‍

1. Make the brownie batter. The brownie batter is a simple one. Start by whisking together oil, eggs, and vanilla extract. In a large mixing bowl, combine flour, sugar, cocoa powder, and salt. Then use a rubber spatula to incorporate the wet ingredients into the dry ingredients until fully combined.
   
   
2. Bake the brownies. Spread the brownie batter evenly into a 9” x 9” square baking pan that is lightly greased with nonstick cooking spray and lined with parchment paper. Bake at 350°F for 13-15 minutes, just until the brownie is set. The brownie layer is thin so it doesn’t take long to bake - be sure not to overbake it. Allow it to cool completely before starting to build the ice cream sandwiches.

3. Assemble the sandwiches. Slice the brownie layer in half to create two even rectangles. Line a large 9” x 5” loaf pan with parchment paper or plastic wrap - this is how we’ll build the sandwiches. Place one brownie layer on the bottom then scoop about ⅔ of a 1 ½ quart carton of mint chocolate chip ice cream on top. Spread the ice cream evenly and all the way out to the edges of the pan then top with the remaining brownie layer and press down.
   
   

4. Freeze. Freeze the ice cream bar for at least 6 hours or overnight, until the ice cream is firm.
   
   
5. Slice and enjoy! Use the parchment (or plastic wrap) that you lined the pan with to pull the ice cream bar from the pan. Trim off any uneven edges then cut into 8 equal squares. Enjoy right away or wrap individually and return to the freezer until ready to serve.

Tips for the Best Brownies

‍

• Spread batter evenly. The brownie layer is meant to be fairly thin so making it an even layer is important. Use an offset spatula to spread the brownie batter out to the edges and get it as evenly as possible so you end up with equal-sized brownie layers.
  
  
• Don’t overbake. For a perfectly soft and chewy brownie, you want to make sure it doesn’t get overbaked. Bake the brownie layer for the minimum amount of time listed in the recipe (13 minutes) to start and check on them before adding more time, if needed. Only add 1-2 minutes at a time and bake just until the brownie is set, or until a toothpick inserted in the middle comes out with a few moist crumbs (a clean toothpick means they’re overbaked).
  
  
• Allow to cool completely. The brownie needs to be cooled down completely before layering it with the ice cream. A warm brownie layer is going to be too difficult to handle and make the ice cream melt even faster. You can pop the brownie layer in the freezer for 10-15 minutes to speed up the cooling process.

Brownie Ice Cream Sandwich FAQs

‍

Can I bake the brownie layers in two loaf pans?

Yes. If you have two loaf pans that are the same size, you can split the brownie batter evenly between the two pans instead of using a 9” x 9” pan and cutting the layer in half. The bake time may need to be reduced slightly and I  recommend building the ice cream bar in the loaf pan that you used to bake the layers in.

‍

What other ice cream flavors can I use?

Any flavor you’d like! These ice cream sandwiches can be customized with whatever you like best. Other ice cream flavors that would pair well with the brownie layers: 

• Vanilla Bean
• Strawberry
• Birthday Cake
• Coffee
• Caramel Swirl
• Cookies & cream

‍

How should I store the ice cream sandwiches?

These keep best when wrapped individually wrapped in plastic wrap or wax paper. I also recommend placing the ice cream sandwiches in a zip-top bag or airtight container after individually wrapping each one, to help prevent freezer burn. Store in the freezer for up to a month.
