1. Prepare the Cake Base
- Melt the Butter:
- In a medium saucepan, melt the unsalted butter over medium heat. Once melted, remove from heat and stir in the peanut butter until smooth.
- Mix Sugar and Milk:
- In a separate bowl, combine the granulated sugar with the milk. Stir until the sugar is completely dissolved.
- Prepare the Pudding:
- Add the instant vanilla pudding mix to the milk and sugar mixture. Whisk thoroughly for 2 minutes until the mixture begins to thicken.
- Combine Ingredients:
- Blend the melted butter and peanut butter mixture into the pudding mixture. Ensure it’s well combined.
2. Assemble the Cake
- Prepare the Cream Cheese Mixture:
- In a large mixing bowl, beat the softened cream cheese until smooth. Gradually fold in the Cool Whip or whipped topping until fully incorporated.
- Layer the Graham Crackers:
- Line the bottom of a 9×13-inch baking dish with a layer of graham crackers.
- Spread the Filling:
- Evenly spread half of the peanut butter pudding mixture over the graham crackers.
- Add Another Layer:
- Place another layer of graham crackers over the pudding mixture. Spread the remaining pudding mixture on top.
- Top with Cream Cheese Mixture:
- Spread the cream cheese and Cool Whip mixture evenly over the top layer of graham crackers.
3. Prepare the Peanut Butter Frosting
- Mix Peanut Butter Frosting:
- In a medium bowl, whisk together the creamy peanut butter, powdered sugar, milk, and vanilla extract until smooth and spreadable.
- Frost the Cake:
- Spread the peanut butter frosting over the cream cheese layer.
4. Add the Chocolate Drizzle (Optional)
- Melt Chocolate:
- In a microwave-safe bowl, heat the semi-sweet chocolate chips with heavy cream in 20-second intervals, stirring in between until smooth.
- Drizzle Over the Cake:
- Drizzle the melted chocolate over the peanut butter frosting in a decorative pattern.
5. Chill and Serve
- Refrigerate:
- Cover the cake with plastic wrap and refrigerate for at least 4 hours or overnight. This allows the flavors to meld and the cake to set properly.
- Serve:
- Slice into squares and serve chilled. The cake can be stored in the refrigerator for up to 5 days.
Tips for Success
- Even Layers: Ensure each layer is even for the best texture and presentation. Use a spatula to smooth out the layers.
- Chilling Time: Allow sufficient chilling time to let the cake firm up. This step is crucial for the best texture.
- Custom Variations: Feel free to incorporate variations such as adding chopped peanuts or using flavored pudding mixes to suit your taste preferences.
