Ingredients

Gather the following ingredients:

• 1 cup all-purpose flour
• 1/2 cup unsweetened cocoa powder
• 1/2 teaspoon baking powder
• 1/4 teaspoon baking soda
• 1/4 teaspoon salt
• 1/2 cup unsalted butter, softened
• 1/2 cup granulated sugar
• 1/2 cup brown sugar, packed
• 2 large eggs, room temperature
• 1 teaspoon vanilla extract
• 1/2 cup buttermilk (or dairy-free substitute)
• 1/2 cup hot water
• 1/2 cup creamy peanut butter
• 1/4 cup chocolate chips for topping

Substitutions: Use a 1:1 gluten-free flour blend to make these gluten-free, or replace buttermilk with dairy-free milk combined with a splash of lemon juice for a non-dairy option. For a nut-free variation, substitute sunflower seed butter for the peanut butter.

How to Make Chocolate Peanut Butter Lava Cupcakes

1. Preheat the oven: Heat oven to 350°F (175°C) and line a 12-cup muffin tin with liners.
2. Combine dry ingredients: In a medium bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt until evenly mixed.
3. Cream butter and sugars: In a large bowl, beat the softened butter with granulated and brown sugar until light and fluffy. Add the eggs one at a time, mixing well after each. Stir in the vanilla.
4. Mix wet and dry: Alternate adding the dry ingredients and buttermilk to the butter mixture, beginning and ending with the dry ingredients. Mix gently until just combined—avoid overmixing.
5. Smooth the batter: Stir in the hot water until the batter becomes smooth; this step blooms the cocoa and deepens the chocolate flavor.
6. Fill liners and add filling: Spoon batter into liners, filling each about two-thirds full. Place about a tablespoon of creamy peanut butter into the center of each cupcake, pressing it slightly into the batter so it remains embedded while baking.
7. Bake: Bake 18–20 minutes, or until the tops spring back lightly when touched. The centers should remain soft for the lava effect.
8. Cool and finish: Let cupcakes cool in the pan for 5 minutes, then transfer to a wire rack. Once cooled, top with an extra dollop of peanut butter and sprinkle with chocolate chips, if desired.

Helpful Tips

• Enhance the lava: For a more pronounced molten center, add an additional spoonful of peanut butter or use a slightly softer peanut butter so it melts more easily.
• Room temperature ingredients: Use room-temperature butter and eggs for a smooth, well-emulsified batter and better rise.
• Avoid overmixing: Stir the batter only until ingredients are combined. Overmixing can develop gluten and make cupcakes dense.
• Even portions: Use a cookie scoop to portion batter evenly so cupcakes bake at the same rate.
• Test for doneness: The centers should still be soft; don’t rely solely on toothpick tests near the peanut butter—check the cake around the edges.

Serving Suggestions

• Serve warm with a scoop of vanilla ice cream to contrast the warm center.
• Drizzle with chocolate ganache or melted chocolate for extra richness.
• Garnish with chopped roasted peanuts or a dusting of cocoa powder for texture and visual appeal.
