Step-by-Step Peanut Butter Cupcake Recipe
1. Preheat Your Oven
Set your oven to 350°F (175°C). Line a muffin tin with cupcake liners.
2. Mix Dry Ingredients
In a bowl, whisk together flour, baking powder, and salt. Set aside.
3. Cream Butter, Peanut Butter, and Sugar
In a separate bowl, beat the butter, peanut butter, and sugar until light and fluffy. This takes about 2-3 minutes.
4. Add Eggs and Vanilla
Beat in eggs, one at a time, then mix in the vanilla extract.
5. Combine Wet and Dry Ingredients
Alternate adding the dry ingredients and milk, mixing until just combined.
6. Fill Cupcake Liners
Spoon the batter evenly into the prepared cupcake liners, filling each about 3/4 full.
7. Bake
Bake for 18-22 minutes or until a toothpick inserted in the center comes out clean.
8. Cool Completely
Let cupcakes cool in the pan for 5 minutes, then transfer to a wire rack.
9. Frost and Enjoy
Once completely cool, top with frosting if desired.

Tips for Success
- Use room temperature ingredients – This ensures even mixing.
- Don’t overmix the batter – Overmixing can make the cupcakes dense.
- Let cupcakes cool completely before frosting – Warm cupcakes can melt the frosting.
- Store properly – Keep in an airtight container for freshness.
Common Mistakes and How to Avoid Them
- Dense cupcakes? Overmixing the batter can cause this. Mix just until combined.
- Dry cupcakes? Too much flour or overbaking can dry them out. Measure accurately and check doneness early.
- Sinking cupcakes? Your baking powder might be expired, or you opened the oven too soon.
