I’m a huge fan of ice cream. Seriously. Any chance I get to play with an ice cream flavor in my baked goods, I’m all in. So, this kid-favorite recipe from The Weeknight Dessert Cookbook clearly needed to be made again.

These rocky road brownies are crazy rich. You’ll note that the recipe card shows there are 24 servings in an 8-inch pan. While the photos are of 12 larger brownies, I’ve found that a smaller slice is perfect for most people.

Marshmallow Brownies

If you’ve never tried making brownies with marshmallows before, you are missing out. There’s something so amazing about the way that marshmallows transform when baked in the oven.

They bloom into tiny pockets of gooey goodness that contrast beautifully with the dense texture of the brownie. And, the flavors are perfect for one another–chocolate is brooding, dark, and intense, while marshmallows bring a lighter, vanilla sweetness. It’s a match made in culinary heaven.

Start by preheating the oven to 325°F. Grease an 8-inch square pan with butter or line with parchment. Then, melt the butter in a medium saucepan over medium-high heat.

Add 1 cup chocolate chips to the butter and melt. Then, remove from the heat and stir in the sugar and vanilla until smooth. Whisk in the eggs, then stir in the flour and salt until well combined.

Fold in 2 cups marshmallows and ¾ cup chocolate chips, then pour the brownie batter into the prepared pan. Sprinkle with the remaining marshmallows.

Bake for 26-28 minutes, until a toothpick inserted in the center of the brownies comes out with wet crumbs. While the brownies are in the oven, microwave the cream in a medium glass bowl until simmering, about 60-90 seconds.

Remove the brownies from the oven and pour the frosting over the top. Sprinkle with almonds. Let cool completely before slicing.
