Banana Split Sundae Ice Cream Cake ingredients

Ingredients You’ll Need

  • 1 1/2 cups graham cracker crumbs
  • 1/2 cup butter, melted (plus 1/4 cup reserved)
  • 3 bananas, sliced
  • 1 gallon softened ice cream (vanilla or your favorite flavor)
  • 1 cup chopped nuts (walnuts or pecans work great)
  • 1 cup chocolate chips
  • 1 cup confectioner’s sugar
  • 1 cup evaporated milk
  • 1 tsp vanilla extract
  • 1 tub whipped topping

How to Make This Easy Ice Cream Cake Recipe

Don’t worry if you’re new to making ice cream cakes—this no bake sundae cake is as straightforward as it gets. Just follow these ten easy steps:

  1. In a small bowl, mix the graham cracker crumbs and melted butter. Reserve 1/4 cup of this mix for later.
  2. Press the remaining graham cracker mixture firmly into the bottom of a 9 x 13-inch pan. This creates a buttery crust base that holds everything together.
  3. Layer sliced bananas evenly over the crust. It’s the first step to that classic banana split flavor!
  4. Spread the softened ice cream over the bananas, smoothing the top as best you can.
  5. Sprinkle the chopped nuts on top of the ice cream layer for crunch.
  6. Cover the pan with plastic wrap and freeze for about 2 hours, or until firm.
  7. While the cake chills, prepare the chocolate sauce. In a medium saucepan over medium heat, melt chocolate chips with the remaining 1/4 cup butter, stirring until smooth.
  8. Add confectioner’s sugar and evaporated milk to the melted chocolate. Stir constantly and cook for about 8 minutes until the sauce thickens slightly but stays pourable. Remove from heat and stir in vanilla extract. Let cool, stirring occasionally for about 30 minutes.
  9. Pour the cooled chocolate sauce over the ice cream layer and freeze for another hour.
  10. Spread whipped topping evenly over the chocolate layer, sprinkle with the reserved graham cracker crumbs, and freeze at least 4 hours or overnight for best results.

Baking & Dessert Tips from Emily

  • Softening ice cream: Let it soften just enough to spread easily but not melt fully. Think “creamy playdough” texture.
  • Pressing the crust: Pat the graham cracker crust firmly with the back of a spoon or your hand so it won’t crumble when slicing.
  • Chocolate sauce stirring: Keep stirring to prevent burning – nobody wants crunchy chocolate chunks in this velvety sauce!
  • Freeze time patience: I know the waiting is hard, but freezing is key for slicing clean pieces. Maybe catch up on a show or call a friend.
  • Texture tip: If your nuts are too hard, toast them lightly for extra flavor and crunch without overwhelming the creaminess.
