Ingredients You’ll Need
You don’t need anything fancy to make showstopping Gooey Chocolate Peanut Butter Cupcakes—it’s all about the right balance of pantry staples and a little bit of kitchen love. Each ingredient brings something essential, from rich flavor and tender crumb to that gooey center everyone raves about.
- All-purpose flour: Gives the cupcakes structure while keeping them fluffy and soft.
- Unsweetened cocoa powder: Deep chocolate flavor is a must—choose a good quality cocoa powder for the best taste.
- Baking soda: Helps the cupcakes rise and stay beautifully light.
- Salt: Enhances the flavors and balances the sweetness.
- Granulated sugar: Sweetens the cupcakes just right and gives a nice crumb.
- Packed brown sugar: Adds moisture and a subtle caramel note that pairs perfectly with peanut butter.
- Unsalted butter (melted): Gives richness and depth—the base for moist cupcakes.
- Large eggs: Bind everything together and provide a tender texture.
- Vanilla extract: Rounds out the flavors with warmth and aroma.
- Sour cream: This is the secret to extra-moist, tangy cupcakes that melt in your mouth.
- Milk: Loosens the batter for a perfectly smooth consistency.

How to Make Gooey Chocolate Peanut Butter Cupcakes
Step 1: Prep Your Pan and Oven
Begin your adventure by preheating the oven to 350°F (175°C). Line a standard 12-cup muffin tin with cupcake liners—trust me, no one wants to wrestle a gooey cupcake out of an unlined tin! This little step sets the stage for flawless cupcakes later.
Step 2: Mix Up Your Dry Ingredients
In a medium bowl, whisk together the flour, unsweetened cocoa powder, baking soda, and salt. Whisking helps distribute everything evenly, preventing little clumps and ensuring every bite is pure chocolate-peanut-butter bliss.
Step 3: Cream Sugars and Butter
Grab a larger bowl and mix both sugars with melted butter until the mixture gets glossy and wonderfully aromatic. This combo creates ultra-moist cupcakes with just a hint of caramel sweetness from the brown sugar.
Step 4: Add the Wet Ingredients
Add the eggs one at a time, blending well after each. Then stir in the vanilla, sour cream, and milk. The sour cream is your secret weapon for fluffy, tender cupcakes—don’t skip it! Once combined, your batter will look silky and inviting.
Step 5: Combine Wet and Dry Mixtures
Gradually mix the dry mixture into the wet, stirring just until smooth. Don’t overmix; a gentle hand keeps these cupcakes soft. Next, gently fold in the mini chocolate chips for extra gooeyness.
Step 6: Make the Peanut Butter Filling
In a small bowl, stir together the creamy peanut butter, powdered sugar, and softened butter until smooth. This becomes creamy pockets of peanut-buttery heaven—the star of your Gooey Chocolate Peanut Butter Cupcakes!
Step 7: Assemble Your Cupcakes
Scoop about 2 tablespoons of chocolate batter into each cupcake liner. Press a mini peanut butter cup into the center of each, then dollop a spoonful of peanut butter filling on top. Cover everything up with another spoonful of batter, filling the liner about 3/4 full.
Step 8: Bake and Cool
Bake for 18–22 minutes, or until the cupcake tops spring back lightly when touched. Let them cool in the pan for 5 minutes (to let the gooey center set), then carefully transfer to a wire rack to cool completely. The wait is hard, but oh-so worth it!
How to Serve Gooey Chocolate Peanut Butter Cupcakes
Garnishes
For that drool-worthy bakery look, top your Gooey Chocolate Peanut Butter Cupcakes with a drizzle of chocolate ganache, a sprinkle of crushed peanut butter cups, or even a swirl of whipped peanut butter frosting. If you’re really going for it, add a pinch of flaky sea salt for a grown-up twist.
Side Dishes
These cupcakes shine on their own, but they pair beautifully with a scoop of vanilla ice cream, a tall glass of milk, or a cup of coffee (especially if you crave that bittersweet balance). For dessert platters, fresh strawberries and salty pretzel sticks make playful, tasty sides.
Creative Ways to Present
Stack the cupcakes high on a tiered cake stand for a showstopper centerpiece, or serve them nestled in colorful liners for a festive pop at parties. Wrap each cupcake in clear cellophane and tie with a ribbon for charming edible gifts—the gooey, chocolate-peanut butter surprise inside is such a joyous reveal!
Make Ahead and Storage
Storing Leftovers
If you have leftover Gooey Chocolate Peanut Butter Cupcakes (which is rare!), store them in an airtight container at room temperature for up to 2 days. After that, pop them in the fridge to maintain peak freshness for a couple more days—the filling stays ultra-gooey!
Freezing
To freeze, let the cupcakes cool completely, then wrap them individually in plastic wrap and seal them in a freezer bag or container. They’ll keep for up to 3 months. Thaw at room temperature or in the fridge overnight, and they’ll taste like you just baked them.
Reheating
For that just-baked gooeyness, warm a cupcake in the microwave for 10–15 seconds. The center will turn extra melty and the chocolate chips will get delightfully gooey again. Just be careful—one bite leads to another!
FAQs
Can I make Gooey Chocolate Peanut Butter Cupcakes gluten-free?
Absolutely! Swap in a good-quality 1:1 gluten-free all-purpose flour blend for the regular flour. Everything else stays the same, so you’ll still enjoy that signature gooey, soft cupcake charm.
Do I need to freeze the peanut butter cups before baking?
It’s not required, but if you want an especially gooey center, popping the peanut butter cups in the freezer for 15–20 minutes before assembling the cupcakes works magic. They melt more slowly, so you get that dreamy gooey core.
How do I know when the cupcakes are done baking?
Gently press the top of a cupcake with your finger; if it springs back, they’re ready! A toothpick inserted on the edge (not the center, thanks to the filling) should come out with a few moist crumbs—not wet batter.
Can I double the recipe for a crowd?
Go for it! Just double all the ingredients and bake in batches if your oven can’t fit two trays comfortably. These Gooey Chocolate Peanut Butter Cupcakes are built for sharing (though hoarding is understandable).
What’s the best way to frost or decorate these cupcakes?
A simple drizzle of chocolate ganache or peanut butter glaze is heavenly, but you can also pipe a swirl of your favorite chocolate or peanut butter buttercream on top. Add mini chocolate chips or chopped peanuts for crunch and flair.
Final Thoughts
These Gooey Chocolate Peanut Butter Cupcakes are pure happiness in cupcake form—so easy to love, and even easier to make disappear. Whether you’re baking for a special occasion or just a cozy night in, you deserve this decadent treat. Grab your ingredients and get ready to bake up a batch of pure joy!
