Instructions

Let’s dive into the steps to create this flavorful masterpiece:

Preheat Your Equipment

Start by preheating your oven to 350°F (175°C). Line a muffin tin with paper cupcake liners to prevent sticking and keep cleanup easy.

Combine Dry Ingredients

In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. This dry mix will give your cupcakes the perfect fluffy lift.

Mix Wet Ingredients

In a large mixing bowl, cream together the butter and peanut butter until light and smooth. Add the sugar and beat until fluffy. Then mix in the eggs one at a time, followed by the vanilla extract.

Combine Wet and Dry

Alternately add the dry mixture and milk to your peanut butter batter, mixing until just combined. Don’t overmix—just stir until everything’s cozy and incorporated.

Fill the Cupcake Liners

Spoon a tablespoon of batter into each liner. Add a teaspoon of jam in the center, then cover with another tablespoon of batter. The jam will sink slightly and bake into the center—yum!

Bake to Perfection

Bake for 18–22 minutes, or until the tops are golden and a toothpick inserted near the edge comes out clean (avoid the jammy center when testing). Let cool completely on a wire rack before frosting.

Make the Frosting

Beat peanut butter and butter until smooth. Add powdered sugar gradually, then mix in vanilla and heavy cream. Whip until fluffy and pipeable.

Decorate and Serve

Frost the cooled cupcakes using a piping bag or spoon. Drizzle with extra jelly or swirl it into the frosting for a beautiful marbled effect. Garnish with chopped peanuts or a PB&J cookie for extra flair.

How to Serve Swirled Sweetheart Cupcakes

These cupcakes are the star of any dessert spread, but they also shine on their own. Here’s how to elevate the experience:

For Kids’ Lunchboxes: Wrap them individually for a lunchtime surprise they’ll brag about.

Additional Tips

Use Room-Temperature Ingredients: This helps everything mix more evenly and ensures a smoother batter.
Don’t Overfill Liners: Jam expands—so leave room for these cupcakes to rise without overflowing.
Make Ahead: Bake the cupcakes a day early and frost them the next day for best results.
Storage: Store in an airtight container at room temperature for 2 days, or refrigerate up to 5.
Freezer-Friendly: Freeze unfrosted cupcakes for up to 2 months. Thaw and frost when ready.
