Ingredients for Peanut Butter Brownie Cups

Here’s what you’ll need to make this delicious Peanut Butter Brownie Cups:

1 box brownie mix – Choose a brand that you love, as this is the base of our delightful cups.

2 large eggs – Fresh eggs help bind the mix together and add a fluffy texture to the brownies.

1/2 cup vegetable oil – This adds moisture and richness to the brownies; you can also use melted coconut oil for a different flavor.

1/2 cup creamy peanut butter – Use your favorite brand for smooth, velvety filling that’s essential for that peanut butter goodness.

1/3 cup powdered sugar – This adds sweetness and helps thicken the peanut butter filling to perfection.

1/2 teaspoon vanilla extract – A touch of vanilla enhances the overall flavor and adds an aromatic essence.

1/2 cup semi-sweet chocolate chips – Use good-quality chocolate chips for a gooey topping that melts perfectly over the brownie cups.

How to Make Peanut Butter Brownie Cups

Follow these simple steps to prepare this delicious Peanut Butter Brownie Cups:

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) and line a muffin tin with cupcake liners or generously spray it with nonstick cooking spray.

Step 2: Prepare the Brownie Batter
In a medium bowl, prepare the brownie mix according to package instructions, adding the eggs and vegetable oil as directed. Stir until just combined, making sure there are no dry spots.

Step 3: Fill the Muffin Tin
Spoon the brownie batter into each muffin cup, filling them about two-thirds full. This gives them enough space to rise beautifully without overflowing.

Step 4: Bake the Brownie Cups
Place the muffin tin in the preheated oven and bake for about 18-20 minutes. Check for doneness by inserting a toothpick in the center; it should come out mostly clean, with a few moist crumbs.

Step 5: Make the Peanut Butter Filling
While the brownie cups are cooling, blend the creamy peanut butter, powdered sugar, and vanilla extract together in a small bowl until smooth and creamy. This will be the heavenly filling that makes these cups irresistible.

Step 6: Create a Well for the Filling
Once the brownie cups are cool enough to handle, gently press the center of each cup with your thumb or the back of a spoon to create a little well for the peanut butter filling.

Step 7: Fill with Peanut Butter
Spoon the creamy peanut butter filling into each well you’ve created, generously filling them for maximum indulgence.

Step 8: Top with Chocolate Chips
While the cups are still warm, sprinkle semi-sweet chocolate chips over each one. The heat will melt them slightly, creating a luscious topping.

Step 9: Cool and Serve
Allow the brownie cups to cool completely in the muffin tin. Once cooled, gently remove them and serve immediately, or store them in an airtight container for up to a week.

These Peanut Butter Brownie Cups are killer delicious and perfect for an afternoon treat or as a crowd-pleasing dessert at parties. Don’t be surprised if they become your signature bake. Go ahead; make them for yourself and watch as everyone asks for the recipe!
