What Kind of Peanut Butter Works Best for Peanut Butter Brownie Cups?

Creamy peanut butter is ideal for that ultra-smooth, dreamy topping, but you can absolutely use crunchy peanut butter if you want extra texture and a little salty crunch. Make sure to use a shelf-stable peanut butter for the topping so it holds its shape and stays creamy after chilling. Natural peanut butters can separate or get oily, so a classic peanut butter (like Jif or Skippy) will give you the most reliable results.

Ingredients for the Peanut Butter Brownie Cups

Every ingredient in this recipe serves a delicious purpose. Here’s what you’ll need:

• Unsalted Butter: Adds richness and keeps the brownies tender. Melting it helps blend everything smoothly.
• Granulated Sugar: Sweetens the brownies and helps create that classic crackly top.
• Light Brown Sugar: Boosts moisture and adds a subtle caramel note.
• Large Eggs: Provide structure and create a fudgy texture.
• Pure Vanilla Extract: Enhances all the chocolate and peanut butter flavors.
• All-Purpose Flour: Gives the brownies structure while keeping them soft.
• Unsweetened Cocoa Powder: The base of all that chocolatey goodness—use Dutch-processed for deeper flavor, but regular works too.
• Salt: Balances the sweetness and makes every bite pop.
• Baking Powder: Adds a gentle lift, making the brownie cups a touch cakier around the edges while staying fudgy inside.
• Semi-Sweet Chocolate Chips: For melty chocolate pockets throughout the brownies and for topping.
• Creamy Peanut Butter: The star of the topping. Choose a classic, no-stir variety for the best texture.
• Powdered Sugar: Sweetens and thickens the peanut butter layer.
• Milk: Helps smooth out the peanut butter topping to spreadable consistency.
• Chocolate Chips or Melting Wafers (for drizzle): To create that picture-perfect finishing touch on top.

How To Make the Peanut Butter Brownie Cups

Let’s break down this easy, irresistible treat step by step:

Step 1: Prep the Pan and Oven

Preheat your oven to 350°F (175°C). Line a standard 12-cup muffin tin with paper liners or spray generously with nonstick spray.

Step 2: Make the Brownie Batter

Melt 1/2 cup (1 stick) unsalted butter in a microwave-safe bowl. Whisk in 1/2 cup granulated sugar and 1/2 cup light brown sugar until smooth. Add 2 large eggs and 2 teaspoons vanilla extract, mixing well. Stir in 1/2 cup all-purpose flour, 1/3 cup unsweetened cocoa powder, 1/2 teaspoon salt, and 1/2 teaspoon baking powder until just combined. Fold in 2/3 cup semi-sweet chocolate chips.

Step 3: Bake the Brownie Cups

Spoon the batter evenly into the 12 prepared muffin cups (they’ll be about 3/4 full). Bake for 15-17 minutes, until the tops look set but a toothpick inserted into the center comes out with a few moist crumbs. Let them cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.

Step 4: Make the Peanut Butter Topping

While the brownies cool, beat together 3/4 cup creamy peanut butter, 1/2 cup powdered sugar, and 2-3 tablespoons milk until smooth and creamy. The topping should be thick but spreadable.

Step 5: Top the Brownie Cups

Once the brownie cups are cool, spread or pipe the peanut butter mixture onto each one. If you like, swirl with the back of a spoon for a bakery-style look.

Step 6: Drizzle with Chocolate

Melt 1/3 cup chocolate chips or melting wafers in the microwave in 20-second intervals, stirring until smooth. Drizzle over the peanut butter layer. Garnish with extra chocolate chips if desired. Let set before serving or chilling.

Frequently Asked Questions

Absolutely—swap in your favorite 1:1 gluten-free flour blend. Check all other ingredients to confirm they’re gluten-free as well.
