Ingredients You’ll Need
You don’t need a pantry full of fancy items to whip up these delectable cupcakes. Each ingredient is thoughtfully chosen to contribute the perfect texture, flavor balance, and moist crumb that makes these cupcakes stand out.
- 1 cup all-purpose flour: Provides the essential structure for your cupcakes, ensuring they hold their shape wonderfully.
- ½ cup unsweetened cocoa powder: Adds deep chocolate richness without extra sweetness.
- 1 tsp baking powder: Helps the cupcakes rise beautifully, giving you a light texture.
- ½ tsp baking soda: Works alongside the baking powder for perfect lift and tenderness.
- ¼ tsp salt: Enhances all the flavors, balancing sweetness and chocolate tones.
- ½ cup granulated sugar: Sweetens the batter evenly for a classic cupcake flavor.
- ½ cup brown sugar, packed: Brings a subtle molasses note that enriches the cupcake’s depth.
- 2 large eggs: Acts as a binder, contributing to fluffiness and moisture.
- ½ cup buttermilk: Adds tang and keeps the crumb tender and moist.
- ½ cup vegetable oil: Ensures a soft, moist texture that lasts.
- 1 tsp vanilla extract: Lifts all chocolate and peanut butter flavors with warm sweetness.
- ½ cup hot water: Intensifies cocoa flavor and creates a smooth batter.
- ½ cup creamy peanut butter: The heart of the lava, offering that luscious gooey center everyone will love.
- ¼ cup powdered sugar: Sweetens and stabilizes the peanut butter filling for perfect consistency.
- Whipped cream or chocolate drizzle (for serving): Optional touches that add presentation flair and extra indulgence.
How to Make Gooey Peanut Butter Lava Cupcakes Recipe
Step 1: Preheat and Prepare Your Pan
Start by setting your oven to 350°F (175°C) and line a muffin tin with cupcake liners. This simple step ensures even cooking and makes cleanup a breeze while giving your cupcakes their classic look.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the flour, unsweetened cocoa powder, baking powder, baking soda, and salt. Taking the time to mix these thoroughly prevents lumps and promotes a smooth, tender crumb in the final cupcakes.
Step 3: Combine the Wet Ingredients
In a second larger bowl, beat together the granulated sugar, brown sugar, eggs, buttermilk, vegetable oil, and vanilla extract until the mixture is smooth and glossy. This creates a luscious base that keeps your cupcakes moist and flavorful.
Step 4: Bring the Batter Together
Gradually add your dry ingredients to the wet mixture, stirring gently until just combined. Avoid overmixing here to keep your cupcakes light. Then, stir in the hot water carefully—this will amp up the cocoa flavor and make the batter silky smooth.
Step 5: Prepare the Peanut Butter Lava Filling
In a separate bowl, mix the creamy peanut butter with powdered sugar until smooth and slightly thickened. Roll the mixture into small 1 teaspoon-sized balls—these are the precious molten centers that will ooze out as you bite in.
Step 6: Assemble Your Cupcakes
Fill each cupcake liner halfway with the chocolate batter, then gently place a peanut butter ball in the middle. Cover the peanut butter with more batter, filling the liners about three-quarters full to leave room for rising without overflowing.
Step 7: Bake to Perfection
Pop your cupcakes into the oven and bake for 18 to 20 minutes. Keep an eye on them; you want the edges to be set and a toothpick inserted near the edge to come out clean, but the center should remain soft and gooey. This contrast is the magic of the Gooey Peanut Butter Lava Cupcakes Recipe.
Step 8: Cool and Garnish
Let the cupcakes cool in the tin for a few minutes before moving them to a wire rack. Serve as is or add a dollop of whipped cream or a drizzle of melted chocolate for an extra fancy touch.
How to Serve Gooey Peanut Butter Lava Cupcakes Recipe

Garnishes
To elevate your cupcakes visually and flavor-wise, try sprinkles of chopped peanuts or a light dusting of cocoa powder. Fresh berries can also add a refreshing contrast to the rich chocolate and peanut butter combo. Whipped cream or a rich chocolate drizzle turns these into a dessert experience worth savoring.
Side Dishes
These cupcakes are delightful on their own but also pair beautifully with a scoop of vanilla ice cream or a small serving of salted caramel sauce for an extra indulgent treat that complements the peanut butter’s creamy saltiness.
Creative Ways to Present
For parties, try placing each cupcake inside mini glass cloches or serving on elegant pedestal plates. You can also add colorful cupcake liners or top with edible gold dust for a fun, festive look that will wow guests and make the Gooey Peanut Butter Lava Cupcakes Recipe stand out on any dessert table.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, store the cupcakes in an airtight container at room temperature for up to two days to preserve that ooey-gooey center while keeping the cupcakes moist and fresh.
Freezing
To keep these treats longer, freeze the baked cupcakes (without garnishes) in a sealed container or freezer bag for up to three months. Thaw overnight in the fridge before reheating gently.
Reheating
Warm your cupcakes in the microwave for about 15 to 20 seconds to bring the peanut butter lava back to its molten goodness. Avoid overheating to prevent drying out the cake.
FAQs
Can I use crunchy peanut butter instead of creamy?
Yes! Crunchy peanut butter adds a delightful texture to the lava center, making each bite even more interesting. Just be sure to mix it well with powdered sugar so the filling holds together nicely.
What if I don’t have buttermilk on hand?
You can easily substitute buttermilk by mixing ½ cup of milk with 1 teaspoon of lemon juice or vinegar and letting it sit for 5 minutes. This adds the needed acidity to keep cupcakes tender and helps balance flavors.
How do I know when the cupcakes are done without overbaking the lava center?
Check the cupcakes by inserting a toothpick near the cupcake’s edges, not the center. It should come out clean or with moist crumbs, signaling that the cake is baked but leaving the peanut butter core soft and gooey.
Can I make these cupcakes gluten-free?
Absolutely! Swap the all-purpose flour for a gluten-free blend that measures cup-for-cup. Just ensure your cocoa powder and other ingredients are gluten-free labeled for best results.
Is there a way to make these cupcakes less sweet?
If you prefer less sweetness, cut down the granulated and brown sugars by a quarter, but keep the powdered sugar in the peanut butter filling as it helps maintain the lava texture. You can also skip the chocolate drizzle garnish or use dark chocolate for a less sweet finish.

Ingredients
Dry Ingredients
- 1 cup all-purpose flour
- ½ cup unsweetened cocoa powder
- 1 tsp baking powder
- ½ tsp baking soda
- ¼ tsp salt
Sugar and Wet Ingredients
- ½ cup granulated sugar
- ½ cup brown sugar, packed
- 2 large eggs
- ½ cup buttermilk
- ½ cup vegetable oil
- 1 tsp vanilla extract
- ½ cup hot water
Peanut Butter Filling
- ½ cup creamy peanut butter
- ¼ cup powdered sugar
For Serving (Optional)
- Whipped cream or chocolate drizzle
Instructions
- Preheat the Oven: Preheat your oven to 350°F (175°C) and line a muffin tin with cupcake liners to prepare for baking.
- Make the Cupcake Batter: In a bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking powder, baking soda, and salt until evenly combined. In a separate larger bowl, beat together the granulated sugar, brown sugar, eggs, buttermilk, vegetable oil, and vanilla extract until smooth. Gradually incorporate the dry ingredients into the wet ingredients, mixing until smooth and uniform. Finally, add the hot water and stir well to form a slightly runny batter.
- Prepare the Peanut Butter Filling: In another bowl, combine the creamy peanut butter with powdered sugar and mix until smooth and creamy. Shape the peanut butter mixture into small balls roughly the size of 1 teaspoon each to create the lava centers.
- Assemble the Cupcakes: Fill each cupcake liner halfway with the prepared batter. Place one peanut butter ball in the center of the batter. Then, cover the peanut butter ball by filling the liners with more batter until they are about ¾ full, ensuring the lava center is completely enclosed.
- Bake the Cupcakes: Bake in the preheated oven for 18-20 minutes. Insert a toothpick into the cupcake edges to check doneness; it should come out clean while the center remains soft and gooey to preserve the lava texture.
- Cool & Serve: Let the cupcakes cool in the tin for a few minutes before transferring to a wire rack. Serve warm, optionally topped with whipped cream or drizzled with melted chocolate for an extra indulgent touch.
Notes
- Make sure not to overbake to keep the peanut butter lava gooey.
- Using hot water in the batter helps bloom the cocoa for richer chocolate flavor.
- Ensure the peanut butter balls are fully covered by batter to prevent leaking during baking.
- You can substitute creamy peanut butter with another nut butter if desired.
- Serve cupcakes slightly warm for the best lava effect.
- Storage: Keep leftover cupcakes in an airtight container at room temperature for up to 2 days or refrigerate for up to 5 days.
