Ingredients You’ll Need

Getting the perfect balance of flavor and texture in these cupcakes is all about having the right ingredients. Each one plays a special role, from the cocoa powder that brings deep chocolate notes to the creamy peanut butter that adds richness and gooey joy. Here’s everything you’ll need:

• 1 cup (120g) all-purpose flour: The base that gives structure and softness to the cupcakes.
• 1/2 cup (50g) unsweetened cocoa powder: For that intense chocolatey flavor that’s rich but not overpowering.
• 1 teaspoon baking powder: Helps your cupcakes rise beautifully and stay light.
• 1/2 teaspoon baking soda: Adds extra lift and helps balance the cocoa’s acidity.
• 1/4 teaspoon salt: Enhances all the sweet and savory flavors.

• 2 large eggs: Bind everything together, giving structure and moisture.
• 1 teaspoon vanilla extract: Brings warmth and depth to the chocolate and peanut butter.

• 1/2 cup (125g) creamy peanut butter (for filling): Soft, luscious filling that melts in your mouth.
• 1/4 cup (30g) powdered sugar (for filling): Sweetens and thickens the peanut butter filling to just the right consistency.
• 1/4 teaspoon vanilla extract (for filling): Adds a little extra flavor boost inside the cupcakes.
• 1/2 cup (115g) unsalted butter, softened (for frosting): Base for the frosting, making it rich and creamy.

How to Make Gooey Chocolate Peanut Butter Cupcakes Recipe

Step 1: Preheat the Oven

Start by preheating your oven to 350°F (175°C). This ensures it’s perfectly hot and ready to bake your cupcakes evenly. Line a 12-cup muffin tin with cupcake liners because this is where all the magic happens!

Step 2: Prepare the Cupcake Batter

Mix the dry ingredients first: sift together the all-purpose flour, cocoa powder, baking powder, baking soda, and salt. This helps distribute everything evenly. In another bowl, cream the softened butter and granulated sugar until light and fluffy — this step is essential for that tender texture. Beat in the eggs one at a time, followed by vanilla extract. Alternate adding the dry ingredients and whole milk to the wet mix, beginning and ending with the dry. The final touch: stir in the boiling water gently until the batter is smooth and glossy, making sure the cupcakes stay moist and chocolatey.

Step 3: Fill the Cupcake Liners

Divide the batter evenly into the liners, filling each about two-thirds full so there’s enough room for rising without overflow. This ensures every cupcake has that perfect domed top.

Step 4: Bake and Cool

Bake for 18 to 20 minutes, or until a toothpick comes out clean. Then, let them cool in the tin for 5 minutes before moving them to a wire rack to cool completely. Completely cooled cupcakes are essential for the next gooey step!

Step 5: Prepare the Peanut Butter Filling

Mix creamy peanut butter, powdered sugar, and vanilla extract until smooth and spreadable. This filling is what takes these cupcakes from delicious to unforgettable, bringing that gooey peanut butter center that makes you want one more bite (and then another).

Step 6: Fill the Cupcakes

Carefully core out the center of each cupcake using a small knife or cupcake corer to create a little well, then generously fill with the peanut butter mixture. Smooth the top with a spoon so it blends nicely underneath the frosting.

Step 7: Prepare the Peanut Butter Frosting

Beat together softened butter and creamy peanut butter until smooth. Gradually add powdered sugar, whole milk, and vanilla extract, beating it all until light and fluffy. This frosting is rich but airy—perfect for swirling onto your cupcakes.

Step 8: Frost the Cupcakes

Pipe the peanut butter frosting onto each cupcake using a star tip for a pretty touch, or spread it on with a knife if you prefer a rustic look. Either way, this frosting is the crowning glory of your gooey creation.

Step 9: Serve and Enjoy

Your Gooey Chocolate Peanut Butter Cupcakes Recipe is now ready to be devoured! Each bite is a perfect combo of moist chocolate, gooey peanut butter, and silky frosting, guaranteed to bring smiles all around.

How to Serve Gooey Chocolate Peanut Butter Cupcakes Recipe

Garnishes

Sprinkle some chopped peanuts or a drizzle of melted chocolate on top of your frosting to add texture and an extra layer of flavor. A small pinch of sea salt can also elevate the peanut butter’s richness and balance the sweetness beautifully.

Side Dishes

Serve these cupcakes with a scoop of vanilla ice cream or a dollop of whipped cream. If you’re feeling fancy, a cup of rich espresso or cold milk makes the perfect companion to keep things balanced and refreshing.

Creative Ways to Present

Try stacking these cupcakes on a tiered cake stand for a stunning dessert display at parties. You can also individually wrap them in clear cellophane tied with a pretty ribbon — they make irresistible gifts! For an eye-catching twist, garnish each with mini Reese’s peanut butter cups or a chocolate curl.

Make Ahead and Storage

Storing Leftovers

Store any leftover cupcakes in an airtight container at room temperature for up to two days to keep them soft and fresh. If you don’t plan to eat them right away, refrigerate to extend their life for about 4 days, but allow them to come to room temperature before serving for the best taste and texture.

Freezing

You can freeze these cupcakes with or without frosting. Place them on a baking sheet to freeze individually, then transfer them to a ziplock bag or airtight container. They’ll keep well up to 3 months. When ready to enjoy, thaw overnight in the fridge for best results.

Reheating

For that just-baked feel, warm cupcakes in the microwave for about 10-15 seconds. This makes the peanut butter core extra gooey and the frosting softens slightly, recreating that fresh-from-the-oven indulgence.

FAQs

Can I use natural peanut butter instead of creamy?

While you can substitute natural peanut butter, its higher oil content and thinner consistency may affect both filling and frosting texture. To compensate, consider stirring in a little extra powdered sugar until you reach the right thickness.

Is there a way to make these cupcakes gluten-free?

Absolutely! Swap the all-purpose flour with a gluten-free baking blend that includes xanthan gum for structure. Just ensure your baking powder and cocoa powder are gluten-free as well for a safe and tasty treat.

Can I make the cupcakes vegan?

With a few swaps, yes! Use a plant-based butter and milk alternative, plus an egg replacer like flax or chia eggs. The peanut butter filling and frosting can easily be adapted by replacing butter with vegan butter and ensuring your powdered sugar is vegan-friendly.

Why do I need to add boiling water to the batter?

Boiling water enhances the cocoa powder’s flavor, making your cupcakes richer and more chocolate-forward. It also helps create a smooth batter that bakes into a moist cake crumb, which is key for these gooey morsels.

Can I prepare the peanut butter filling and frosting ahead of time?

Definitely! Both filling and frosting can be made a day in advance and stored in the fridge. Bring them to room temperature and give them a quick stir or re-whip before using for the best texture and ease of spreading or piping.
