Ingredients

  • 1 1/4 cups flour
  • 1 1/2 teaspoons baking powder
  • 1/2 cup smooth peanut butter
  • 1/2 stick soft butter
  • 1/2 cup packed brown sugar
  • 1 large egg
  • 1/2 teaspoon vanilla
  • 2/3 cup milk

  4. Add flour mixture and milk alternately, beginning and ending with flour, until just combined.
  5. Divide batter among lined muffin cups, about 2/3 full each.

Tips & Substitutions

For an extra peanut buttery flavor, consider adding chopped peanuts or using crunchy peanut butter instead of smooth. If you don't have brown sugar, regular granulated sugar works fine but will alter the moisture slightly. Make sure all ingredients are at room temperature for better mixing. If you're short on time, you can use store-bought Milk Chocolate Icing for convenience.

Serving Suggestions

These peanut butter cupcakes are delicious on their own but can be enhanced with a drizzle of chocolate sauce or a sprinkle of sea salt on top. They pair beautifully with a glass of cold milk or coffee. For a fun twist, serve them alongside Pineapple Pretzel Salad as a refreshing side dish for a summer gathering.

Storage & Reheating

Store leftover cupcakes in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate them for up to a week. To reheat, pop them in the microwave for about 10 seconds or enjoy them cold. If frosted, it’s best to store them in the refrigerator to keep the icing fresh.

Frequently Asked Questions

Can I use whole wheat flour instead of all-purpose flour?

Yes, you can substitute whole wheat flour for all-purpose flour, but the texture may be denser. If you do, consider adding an extra tablespoon of milk to maintain moisture. The nutty flavor of whole wheat will complement the peanut butter nicely.

How can I make these cupcakes gluten-free?

To make gluten-free peanut butter cupcakes, substitute the all-purpose flour with a 1:1 gluten-free baking blend. Ensure that the baking powder is gluten-free as well. This will allow you to enjoy the same delicious flavor while accommodating gluten sensitivities.

What can I use instead of milk in this recipe?

If you're looking for a dairy-free option, you can replace milk with almond milk, soy milk, or coconut milk. Each will impart a slightly different flavor, but they will all work well in this recipe. Just ensure that your peanut butter is also dairy-free if necessary.
