Peanut Butter Brownie Ice Cream Sandwiches

Peanut Butter Brownie Ice Cream Sandwiches

If the Marshmallow Brownies with Salted Almonds, Red Velvet Cheesecake Brownies and Chocolate Chip Brownie Cookies didn’t do it for you, then allow me to introduce you to Peanut Butter Brownie Ice Cream Sandwiches. I may have to hang up the apron after this one. And by “hang up the apron,” I mean “buy a larger apron.”

The key to a killer brownie ice cream sandwich is underbaking the brownies to create a chewy chocolate base. Next up is your choice of ice cream and fillings. While I opted for vanilla bean ice cream that I swirled together with chunky peanut butter, it took all of one bite to dream up endless other pairings:

  • chocolate ice cream with sliced strawberries
  • coffee ice cream with chopped almonds
  • vanilla ice cream with sliced peaches
  • chocolate ice cream with mini marshmallows
  • caramel ice cream with toasted coconut

Who am I kidding? You could sandwich any ice cream flavor with any filling between two chewy brownie slices and I’d eat it. No questions asked. And I have a feeling my food styling assistant, Buckley, would eat it, too.

Peanut Butter Brownie Ice Cream Sandwiches

Yield: 8 servings

Prep Time: 4 hours (includes freezing)

Cook Time: 30 min


10 tablespoons (1 1/4 sticks) unsalted butter
1 1/4 cups sugar
3/4 cup plus 2 Tablespoons unsweetened cocoa powder (natural or Dutch-process)
1/4 teaspoon salt
1 teaspoon vanilla extract
2 large eggs, cold
1/2 cup all-purpose flour
1 pint vanilla ice cream
1/2 cup smooth or chunky peanut butter (optional)

Special equipment: Two square 8-inch metal baking pans


Preheat the oven to 325°F and line the pans with parchment paper leaving an overhang on two sides of each pan.

Combine the butter, sugar, cocoa powder and salt in a heatproof bowl or saucepot. Set the bowl atop a saucepot of simmering water to create a double-boiler. Stir the butter from time to time until it's melted and the mixture is smooth and hot to the touch. Remove the bowl from the double-boiler and set it aside to cool for 10 minutes.

Using a wooden spoon or rubber spatula, stir in the vanilla and then stir in the eggs, one at a time, stirring vigorously between each addition. Once the batter looks well-blended, shiny and thick, stir in the flour until it's fully incorporated. Spread half of the batter into each of the prepared baking pans.

Bake the brownies for 10 to 12 minutes, until a toothpick inserted comes out with a few crumbs. (The brownies should be thin and slightly underbaked so that when they freeze they aren't too difficult to bite into.) Remove the brownies from the oven and let them cool completely (still in the pans) on a wrack.

Microwave the ice cream in 10-second intervals, stirring between each interval, until it's slighty softened, about 20 seconds total. (See Kelly's Notes.)

With the brownies still in the pan, spread the softened ice cream on top of one pan of brownies. Dollop the peanut butter on top of the ice cream, and then using a knife or spatula, swirl the ice cream and peanut butter together. Using the overhangs on the second pan, life the brownies out of the pan and transfer them on top of the ice cream top to form a large sandwich. Cover the pan in plastic wrap and freeze it for at least 3 hours, until the ice cream is firm.

Once firm, unwrap and remove the brownie to a cutting board. Using a serrated knife, slice the brownie in half widthwise and then in fourths lengthwise to form 8 ice cream sandwiches. Serve the ice cream sandwiches immediately or wrap them individually and freeze them until ready to serve.

Kelly's Notes:

There's a bit of an art to microwaving ice cream. Do not attempt to microwave the ice cream for 20 seconds straight or it'll get too soft. The goal is to make the ice cream soft enough to easily spread, but not so soft that it melts all over.

You can make this recipe even if you only have one 8-inch baking pan. Simply bake half the batter in the pan, let the brownies cool completely and then remove them (this will be the top portion of your ice cream sandwiches). Then line the pan again with parchment and bake the second half of the batter, which will stay in the pan and be the bottom of your ice cream sandwiches.

    Kelly, this is my kind of ice cream sandwich! Love the peanut butter addition…mmm! Wonderful baking tips, too, for the brownies. As I was sharing with Averie a while back…”under-baked” is the new perfectly baked, LOL! Thanks for sharing! Pinning everywhere! xo

    I like that you don’t need a special ice cream maker press/cutter to make these (even though I do own one). However, I do not own 2 8 inch square pans, just one 9 and one 8. But when has an extra pan ever been a bad thing? Especially if it means I can have these.

      Not bad at all! And you can actually do this with only one pan by just baking one batch, letting it cool (that will be the top) and then baking the second batch, which will stay in the pan and be the base. I’ll add this tip to the recipe. Thanks, Erin!

    I think you read my mind with this one (seriously, I made brownies last night and was trying to figure out how I could make them into sandwiches)! LOVE the pb/chocolate combo, definitely going to have to try these. :)

      Yay! Enjoy them, Linds!

    What’s not to love about these! I’m wishing I already had some chilling in the freezer for tonight’s Fourth of July celebration.

    What a fun idea for a summer dessert! I would love to wrap these individually and keep them in my freezer to have when I need a sweet treat!

    Do you have the ingredients’ weight in grams? Or maybe a conversion table from cups to grams? I’m from Italy and it’s hard for me to “translate” cups in grams! ><
    I love your recipes, you're awesome!!! ♥ ♥

      Thanks, Silvia! I don’t provide metric conversions for my recipes, as I cannot guarantee they would be 100% accurate without being tested.
