Tips and Tricks

1. Why Use Buttermilk?

• Buttermilk keeps the cake moist and tender while adding a slight tang that balances the sweetness.
• If you don’t have buttermilk, you can make a substitute by mixing 250ml milk with 1 tablespoon vinegar or lemon juice and letting it sit for 5 minutes.

2. Can I Use Crunchy Peanut Butter?

• Yes! If you love extra texture and crunch, substitute half or all of the creamy peanut butter with crunchy peanut butter.

3. How to Store This Cake?

• Store at room temperature in an airtight container for up to 3 days.
• Refrigerate for up to a week, but let it come to room temperature before serving for the best texture.

4. Can I Make This as a Layer Cake?

• Yes! Simply bake in two 9-inch round cake pans and stack with frosting in between the layers.
