Ingredients Equipment Method Notes

Ingredients
  

Brownie mix
  • 1 box brownie mix Use the mix called for on the box.
Instant espresso powder
  • 1 tbsp instant espresso powder Mixed into the brownie mix before baking.
Coffee ice cream
  • 0.5 gallon coffee ice cream Soften until spreadable.
Dark chocolate ganache
  • 1 cup dark chocolate ganache Use a pourable ganache.
Whipped cream
  • 2 cup whipped cream Pipe around the edge and on top.
Espresso/strong coffee
  • 0.25 cup espresso or strong coffee Brush over the cooled brownies.
Chocolate-covered espresso beans
  • 1 chocolate-covered espresso beans Optional but recommended for decoration.

Equipment

  • 1 springform pan

Method
 

Bake and cool the espresso brownies
  1. Preheat the oven to 350°F (175°C), mix brownie batter as directed and stir in the instant espresso powder, then bake in a 9-inch springform pan until a toothpick comes out with moist crumbs. Let the brownies cool completely.
  2. Brush the cooled brownies evenly with the espresso or strong coffee so the surface looks slightly glossy. Set aside until the brushing step soaks in.
Freeze with coffee ice cream layer
  1. Spread the softened coffee ice cream over the brushed brownie layer, smoothing the top with an even, level thickness. Freeze for 4 hours until firm.
Ganache pour and final freeze
  1. Pour the dark chocolate ganache over the frozen cake and tilt the pan to encourage an even coating across the top. Freeze for 2 more hours until the ganache sets.
  2. Pipe whipped cream around the edge and onto the top, then top with chocolate-covered espresso beans for visible speckles. Freeze until ready to serve, keeping the cake firm for clean slices.

Notes

Pro tip: For the cleanest slices, use a hot knife (run under hot water, then wipe dry) between cuts and keep the cake well-frozen. Store covered in the freezer up to 2 weeks; the cake freezes well and can be made ahead. For a lighter option, you can swap in reduced-fat whipped topping while keeping the coffee ice cream layer the same for structure.
