Rich, fudgy brownies filled with homemade ice cream (or use store bough and keep it simple!) and topped with chocolate ganache, whipped cream, chocolate sauce and sprinkles — the perfect cake for a birthday or celebration! Change up the ice cream flavors to suit your tastes!

Yes, I need two titles.

Because I think not everybody knows what to expect when they hear the words “Brownie Mountain”. And because this is really just the most fun you’ve ever had making an ice cream cake, even if it looks like your young child put it together.

I was tempted to name this “Hot Mess Cake”, but I decided that ugly food needs to be loved to. And sprinkles can make almost any cake feel good about itself, am I right? The extra two layer of chocolate on top of the brownie don’t hurt either.

As I was photographing this cake all I could hear in my head was the song “Unpretty” by TLC — tell me you know that song and I’m not that old. But it’s really what’s on the inside that counts, right? And on the inside is no-churn vanilla ice cream. And it’s easy.

I got stole the idea for this cake from the Taste of Home Celebrations cookbook. I didn’t use any of the recipe, as I had my own brownie and ice cream recipes that I like. But I saw it and I knew I had to make it, even though the world is now onto Back To School themed everything and what you really want are granola bars and cookies.

But don’t you think the kiddos deserve a treat for making it through that first week? As a teacher, I’m pretty sure I do most years (though this year I’m going to be at home with my babes as the rest of my colleagues make their way back)!

Optional shortcuts:

If you’re looking to save time, you can always use a boxed brownie mix or store bought ice cream — mix it up by adding any flavors you like!

Instructions 

Brownies

  • Preheat oven to 350℉ and line a 10×15" rimmed baking sheet with foil or parchment paper and spray with non-stick spray.
  • In a large mixing bowl whisk butter and sugar until combined. Whisk in eggs, one at a time. Stir in vanilla.
  • Add the flour, cocoa, and salt and whisk just until combined.
  • Spread into prepared pan and bake for 15-18 minutes until a toothpick comes out clean or with moist crumbs. Cool completely.

Make the brownie ice cream cake

  • Line a 2.5-3 quart bowl with plastic wrap, letting some hang over the sides. Cut brownies into pieces and press brownies into the bowl, cutting and squishing to fit (see photos).
  • Scoop ice cream into the brownie-lined bowl and spread to fill completely. I use two different flavors and alternate scoops for a marbled effect.
  • Place remaining brownies on the top of your ice cream filled bowl (which will end up being the bottom of your mountain). Freeze overnight or until firm.

To decorate

  • Remove from the freezer and let sit for 10-15 minutes or until loose. Unmold your brownie mountain onto a plate and cover almost completely with whipped topping. Set in the freezer to refreeze.
  • In a small pot melt together chocolate bar and ¼ cup whipping cream over low heat until smooth. Set aside to cool for 10 minutes.
  • Drizzle ganache over mountain. Set in the freezer for 15-30 minutes until firm. Decorate as desired and serve. Freeze leftovers until ready to serve, removing about 15 minutes before serving.
