Ingredients You’ll Need for Frozen Brownie Ice Cream Cake
For the Brownie Base
- 1 box brownie mix (18–20 oz) OR homemade brownies
- 2 large eggs (if using boxed mix, follow package instructions)
- ½ cup vegetable oil or melted butter
- 3 tbsp water
(Homemade option: ½ cup butter, 1 cup sugar, 2 eggs, ½ cup cocoa powder, ¾ cup flour, ¼ tsp salt, ½ tsp baking powder)
For the Ice Cream Layer
- 1.5 quarts (6 cups) ice cream (choose 1 or 2 flavors: vanilla, chocolate, cookies & cream, or mint chocolate chip)
- Optional mix-ins: crushed Oreos, chopped nuts, caramel swirls, or chocolate chips
For the Whipped Topping
- 1 ½ cups heavy whipping cream
- 3 tbsp powdered sugar
- 1 tsp vanilla extract
For the Ganache (Optional but Recommended)
- 1 cup semi-sweet chocolate chips
- ¾ cup heavy cream
For Garnish
- Sprinkles, shaved chocolate, fresh berries, or crushed cookies
Step-by-Step Instructions
Step 1: Prepare the Brownie Base
- Preheat oven to 350°F (175°C).
- Grease and line a 9-inch springform pan with parchment paper. (This makes it easier to remove the cake later.)
- Prepare brownie batter according to package directions or homemade recipe.
- Pour batter into the pan and spread evenly.
- Bake for 20–25 minutes until a toothpick comes out with a few moist crumbs. Do not overbake—brownies should be fudgy.
- Let brownies cool completely in the pan. Place in the freezer for 30 minutes while preparing the ice cream layer.
Step 2: Prepare the Ice Cream Layer
- Remove ice cream from the freezer and let it soften at room temperature for about 10–15 minutes until spreadable.
- Once brownies are chilled, spread softened ice cream evenly over the brownie layer using a spatula.
- Tip: Work quickly so the ice cream doesn’t melt too much.
- Variation: Add mix-ins like crushed Oreos or caramel swirls into the softened ice cream before spreading.
- Smooth the top and cover with plastic wrap.
- Freeze for at least 2 hours (overnight is even better).
Step 3: Make the Whipped Topping
- In a large bowl, beat heavy whipping cream, powdered sugar, and vanilla extract with a hand mixer until stiff peaks form.
- Spread whipped cream evenly over the frozen ice cream layer.
- Return to the freezer for at least 1 hour.
Step 4: Prepare the Ganache (Optional)
- Heat heavy cream in a small saucepan until just simmering (do not boil).
- Pour hot cream over chocolate chips in a bowl.
- Let sit for 2 minutes, then whisk until smooth and glossy.
- Allow ganache to cool slightly before pouring over the whipped topping.
- Spread evenly or drizzle for a decorative look.
Step 5: Garnish and Freeze
- Sprinkle with crushed cookies, sprinkles, nuts, or fresh berries.
- Cover with foil or plastic wrap and freeze for at least 6 hours, preferably overnight.
Step 6: Serving
- Remove cake from freezer 10 minutes before serving.
- Release from springform pan and transfer to a serving platter.
- Slice with a sharp knife dipped in hot water (wipe between cuts for clean slices).
- Serve with extra chocolate sauce, caramel drizzle, or fresh fruit if desired.

Pro Tips for Success
- Always freeze between each layer to keep the structure solid.
- Line the springform pan with parchment paper for easy release.
- Mix and match ice cream flavors for a fun twist (e.g., half vanilla, half mint chip).
- Store leftovers wrapped tightly in foil or an airtight container for up to 2 weeks.

Tips for Perfect Frozen Brownie Ice Cream Cake
Freezing Tips
- Always allow enough time for freezing between layers.

Storage and Make-Ahead Options
Freezer Storage
Wrap the cake tightly in plastic wrap or foil to prevent freezer burn. It can last up to 2 weeks.
Make-Ahead for Parties

Common Mistakes to Avoid
Over-Baking the Brownies
Dry brownies won’t hold the ice cream layers well. Aim for fudgy, not cakey.
Using Rock-Hard Ice Cream
Always soften ice cream slightly before spreading; otherwise, the layers won’t be even.
