Creating your own Delicious Brownie Ice Cream Cake involves simple steps to guide you through the process. Follow these instructions carefully:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking dish.
2. Melt Butter: In a medium saucepan, melt unsalted butter over low heat. Remove from heat and allow to cool slightly.
3. Mix Sugar and Eggs: Stir in granulated sugar, mixing until combined. Add eggs one at a time, stirring well after each addition, and mix in vanilla extract.
4. Combine Dry Ingredients: In a separate bowl, mix together flour, cocoa powder, salt, and baking powder.
5. Combine Mixtures: Gradually add dry ingredients to the wet mixture, stirring until well combined and the batter is smooth.
6. Bake the Brownies: Pour the batter into the prepared baking dish and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean. Allow cooling in the pan for at least 30 minutes.
7. Prepare Ice Cream: While the brownies are cooling, soften the ice cream slightly at room temperature for easier spreading.
8. Layer Ice Cream: Once cooled, bake the brownies into even layers. Remove from the pan and place one layer back into the baking dish. Spread a layer of ice cream on top, then cover with the second layer of brownies.
9. Freeze the Cake: Cover the assembled cake with plastic wrap and freeze for at least 2 hours or until set.
10. Add Toppings: Once frozen, remove the cake from the freezer. Top it with whipped cream, chocolate syrup, and any desired garnishes like sprinkles or nuts.
11. Slice and Serve: Cut into squares and serve immediately for the best texture and flavor.

Follow these steps carefully, and you’ll create an incredible dessert that everyone will love!
