- 1 cup granulated sugar
- 1 cup packed light brown sugar
- 4 large eggs
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour

Step-by-Step Instructions
Preheat and Prepare
- Preheat the oven to 350°F (175°C).

Make the Peanut Butter Batter
- In a large bowl, mix the creamy peanut butter, granulated sugar, and brown sugar.
- Use an electric mixer to beat until smooth and creamy.

- Stir in the vanilla extract until everything is blended.
Combine Dry Ingredients
- In another bowl, whisk together the flour, baking powder, and salt.
- Gradually add this mix to the peanut butter mixture. Stir gently.
- Avoid overmixing; this keeps the cupcakes soft and light.
Fill Cupcake Liners
- Fill each liner halfway with batter.
- Add about 1 teaspoon of fudge sauce in the center of each.
- Top with more batter until the liners are ¾ full.
Baking
- Place the cupcake pan in the oven and bake for 18-20 minutes.

Tips & Tricks
Perfecting the Cupcakes
To make the best fudge-filled peanut butter cupcakes, avoid overmixing the batter. When you mix too much, you can make the cupcakes tough. Instead, mix just until the dry ingredients blend in. This will give you a tender texture. Also, use room temperature ingredients. This helps them mix better and create a smooth batter.
Presentation Tips
Presentation matters! Drizzle fudge sauce on top of each cupcake before serving. This adds a rich look and extra flavor. For a nice touch, garnish with crushed peanuts or a sprinkle of sea salt. This contrast makes the cupcakes pop and taste even better.
Baking Substitutions
If you don’t have creamy peanut butter, try using crunchy peanut butter. This gives a fun texture. You can also swap different types of sugar. Brown sugar adds moisture, while granulated sugar gives a nice crust. Experiment with what you have on hand!
Pro Tips
- Use Room Temperature Ingredients: Ensure that your eggs and peanut butter are at room temperature. This helps them blend more easily into a smooth batter, resulting in lighter cupcakes.
- Check for Doneness Early: Start checking your cupcakes a couple of minutes before the minimum baking time. Ovens can vary, and you want to avoid overbaking for the best texture.
- Experiment with Fillings: Feel free to substitute the fudge sauce with other fillings like caramel or fruit preserves to add a unique twist to your cupcakes.
- Storage Tips: Store leftover cupcakes in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week to maintain freshness.
Variations
Flavor Additions
You can make these cupcakes even more fun! Adding different types of chocolate works great. Try dark chocolate chips or white chocolate chunks for new flavors. You could also mix in some chocolate sprinkles for crunch. Experimenting with flavored extracts can add a unique twist too. A hint of almond or mint extract could surprise your taste buds.
Dietary Adjustments
If you need gluten-free options, swap regular flour for almond or coconut flour. These flours give a nice texture while keeping it gluten-free. For vegan substitutes, use flax eggs instead of regular eggs and coconut oil for butter. This way, everyone can enjoy these treats!
Mini Cupcakes or Cake
You can change the size of your cupcakes too. Make mini cupcakes by filling each liner with less batter. This way, you can create bite-sized treats that are perfect for parties. If you want a cake, pour the batter into a round cake pan. You’ll need to bake it a bit longer, but it will still be delicious!
