Common Mistakes to Avoid
Making Chocolate Peanut Butter Cupcakes can be simple, but a few common mistakes can lead to unsatisfactory results. Here are some pitfalls to avoid:

- Overmixing the batter: This can create dense cupcakes. Mix just until combined to keep them light and fluffy.
- Not measuring ingredients accurately: Incorrect measurements can ruin your cupcakes. Use a kitchen scale or measuring cups for precision.
- Skipping the cooling time: Frosting warm cupcakes can melt the frosting. Allow your cupcakes to cool completely before adding frosting.
- Ignoring baking time: Overbaking dries out your cupcakes. Check for doneness a couple of minutes before the suggested time.
