Beat the heat with homemade Mint Chocolate Chip Ice Cream Sandwiches — a simple, impressive summer dessert. These are not the thin wafer sandwiches from childhood, but fudgy brownie layers filled with creamy mint chocolate chip ice cream for a rich, satisfying treat.
The brownies here are chewy and soft even after freezing because the recipe uses oil instead of butter, preventing the edges from getting rock hard. The ice cream can be your favorite brand; mint chocolate chip is a classic pairing, but feel free to customize with any flavor you prefer.
How to Make a Mint Chocolate Chip Ice Cream Sandwich
- Make the brownie batter. Whisk oil, eggs, and vanilla together. In a separate bowl, combine flour, sugar, cocoa powder, and salt. Fold the wet ingredients into the dry with a rubber spatula until just combined.
- Bake the brownies. Spread the batter evenly in a lightly greased 9″ x 9″ pan lined with parchment. Bake at 350°F (175°C) for 13–15 minutes, until the brownies are set but still tender. Because the layer is thin, watch closely to avoid overbaking. Cool completely before assembling.
- Assemble the sandwiches. Slice the cooled brownie layer in half to create two equal rectangles. Line a 9″ x 5″ loaf pan with parchment or plastic wrap to create a sling. Place one brownie rectangle in the bottom, scoop about two-thirds of a 1½‑quart carton of softened mint chocolate chip ice cream on top, and spread it evenly to the edges. Top with the second brownie layer and press gently to seal.
- Freeze. Freeze the assembled ice cream sandwich block for at least 6 hours or overnight, until the ice cream is fully firm.
- Slice and serve. Lift the block from the pan using the parchment or wrap. Trim any uneven edges, then cut into 8 equal squares. Serve immediately or wrap each sandwich individually and return to the freezer.
Tips for the Best Brownies
- Spread the batter evenly. Because the brownie layer is thin, an even spread ensures uniform baking and consistent sandwich portions. An offset spatula helps get a smooth, level surface.
- Avoid overbaking. Start with the lower end of the recommended bake time (around 13 minutes). The brownies should be set but still moist in the center; a few moist crumbs on a toothpick indicate perfect doneness.
- Cool completely before assembling. Warm brownies will melt the ice cream. If you’re short on time, chill the brownie layer in the freezer for 10–15 minutes until cool to the touch.
Mint Chocolate Chip Ice Cream Sandwich FAQs
Can I bake the brownie layers in two loaf pans?
Yes. If you have two identical loaf pans, divide the batter between them and bake. The bake time may be slightly different, so check for doneness earlier. You can assemble the ice cream sandwich in one of the same loaf pans you used to bake.
What other ice cream flavors work well?
Swap the mint chip for any favorite flavor. Delicious options include:
- Vanilla bean
- Strawberry
- Birthday cake
- Coffee
- Caramel swirl
- Cookies & cream
How should I store the sandwiches?
Individually wrap each sandwich in plastic wrap or wax paper, then place them in a zip-top bag or airtight container to prevent freezer burn. Stored this way, they keep well for up to one month.
