Checklist for Peanut Butter Banana Ice Box Cake
- Cottage cheese: Blended until smooth, cottage cheese gives the filling a rich, creamy texture and adds protein.
- All-natural peanut butter: A drippy, natural peanut butter mixes easily and provides authentic peanut flavor.
- Maple syrup: A mild, natural sweetener that pairs well with banana and peanut butter.
- Vanilla wafers: These soften as the cake freezes and add a pleasing cookie texture.
- Mini chocolate chips: Sprinkled between layers for small bursts of chocolate.
- Ripe bananas: Use ripe but not overly brown bananas for the best flavor and texture.
- Blender or food processor: To create a smooth cottage cheese mixture.
Optional toppings
- Fresh whipped cream: A dollop on each slice adds a classic finish.
- Melted peanut butter: Drizzle for extra peanut butter flavor and visual appeal.
- Crushed wafer cookies: Sprinkle on top for crunch.
What other cookies can I use?
Vanilla wafers work beautifully, but graham crackers or another mild, crisp cookie will also pair well with peanut butter and banana. Try different cookies if you want a slightly different flavor or texture—just be mindful of cookie size and thickness when layering.
Other ice box cake variations
Chocolate Strawberry: Use chocolate wafers and layer with sliced strawberries for a chocolate-strawberry twist.
Lemon Blueberry: Swap the peanut butter and bananas for lemon curd and fresh blueberries for a bright, refreshing summer cake.
Oreo Cookies and Cream: Use crushed Oreos in place of vanilla wafers, and top with whipped cream and more crushed Oreos for a cookies-and-cream version.
How to Make Peanut Butter Banana Ice Box Cake
This easy, no-bake recipe is fun to make and great for kids to help with. The process is straightforward: blend the filling, layer the ingredients, and freeze. Below are step-by-step instructions and timing tips.
Ingredients
- Cottage cheese: 24 oz.
- All-natural drippy peanut butter: 1/4 cup
- Maple syrup: 4 tablespoons
- Vanilla wafers: about 48 wafers (divided into two layers of ~24 each)
- Mini chocolate chips: 1/4 cup, divided (use 2 tablespoons on the bottom)
- Bananas: 4 medium, sliced
- Toppings (optional): whipped cream, melted peanut butter, crushed wafers
Instructions
- Blend the filling: Place the cottage cheese in a blender or food processor and blend until completely smooth. Add peanut butter and maple syrup, then blend until fully combined and silky. Set aside.
- Prepare the pan: Line an 8×8-inch baking dish with parchment paper for easier removal and slicing.
- First chocolate layer: Sprinkle 2 tablespoons of mini chocolate chips evenly across the bottom of the lined baking dish.
- First layer of filling: Pour half of the cottage cheese mixture over the chocolate chips and spread evenly.
- Banana layer: Arrange half of the banana slices in a single layer across the filling.
- Cookie layer: Place 24 vanilla wafers in a single, flat layer over the bananas—avoid overlapping if possible.
- Repeat layers: Add the remaining cottage cheese mixture, the remaining banana slices, and finish with another 24 vanilla wafers. Gently press the final layer so everything is compact.
- Cover and freeze: Cover the dish with plastic wrap or foil and freeze for at least 8 hours or overnight until firm.
- Serve: To serve, flip the pan onto a cutting board, peel off the parchment, and allow the cake to sit at room temperature for about 30 minutes before slicing. Add toppings such as whipped cream, a drizzle of melted peanut butter, or crushed wafers if desired.
Our top tip
Line the 8×8-inch pan with parchment paper. This makes it simple to lift the frozen cake out of the pan and slice cleanly once it has softened slightly.
How to store
Store the ice box cake tightly wrapped in plastic wrap or foil in the freezer. It keeps well for up to two weeks. Thaw slightly before serving for easier slicing and a creamier texture.
Tips & notes
- Use ripe bananas for the best sweetness and texture, but avoid overly brown bananas that may become mushy once frozen.
- If you prefer a smoother filling with no detectable curds, strain the cottage cheese briefly or use a high-powered blender until fully smooth.
- Swap the vanilla wafers for graham crackers, chocolate wafers or other cookies to change the flavor profile.
- This recipe is easy to scale up—use a larger pan and increase ingredient quantities proportionally for a crowd.
