Brownie Peanut Butter Cups Made Stepwise

Now, let’s get into the fun part—making these Brownie Peanut Butter Cups!
Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This step is crucial as it ensures even baking of your brownie cups.
Step 2: Prepare the Muffin Tin
Grease a muffin tin or line it with cupcake liners. This will help in easy removal of the brownie cups after baking.
Step 3: Melt Chocolate and Butter
In a microwave-safe bowl, combine the 3/4 cup semi-sweet chocolate chips and the 1/4 cup softened unsalted butter. Microwave in 30-second intervals, stirring in between, until melted and smooth.
Step 4: Mix in Sugar and Egg
Once melted, whisk in the 3/4 cup granulated sugar until well combined. Then, add in the large egg and 1/2 teaspoon vanilla extract, mixing until smooth.
Step 5: Add Dry Ingredients
In a separate bowl, whisk together the 1 cup all-purpose flour and 1/4 teaspoon baking soda. Gradually mix this into your chocolate mixture until just combined.
Step 6: Fold in Peanut Butter Chips
Gently fold in the 1/2 cup peanut butter chips. This will create pockets of peanut butter flavor throughout your brownies.
Step 7: Fill the Muffin Tin
Spoon the brownie batter into each muffin tin cavity, filling them about halfway.
Step 8: Prepare the Peanut Butter Filling
In another bowl, mix the 3/4 cup creamy peanut butter with a little bit of the leftover melted chocolate. This will create a delicious filling.
Step 9: Add the Peanut Butter Filling
Spoon a dollop of the peanut butter mixture on top of the brownie batter in each muffin cup.
Step 10: Top with More Brownie Batter
Cover the peanut butter filling with a bit more brownie batter, making sure to seal it well.
Step 11: Bake
Bake in the preheated oven for about 20-25 minutes, or until a toothpick inserted into the brownie comes out mostly clean.
Step 12: Cool and Garnish
Once baked, let the brownie cups cool in the tin for a few minutes before transferring to a wire rack. Garnish with the extra peanut butter chips and semi-sweet chocolate chips for an extra touch of decadence.
Holiday & Seasonal Touches
These Brownie Peanut Butter Cups can be dressed up for various occasions:
- Sprinkles: Add festive sprinkles for birthdays or holidays.
- Chocolate Drizzle: A drizzle of melted chocolate on top can elevate the presentation.
- Seasonal Flavors: Incorporate peppermint extract for a wintery touch.
- Nuts: Chopped peanuts or walnuts can add crunch and flavor.
Pitfalls & How to Prevent Them
Even the best bakers can encounter challenges. Here are some common pitfalls and how to avoid them:
Overbaking: Keep a close eye on your brownie cups. They should be fudgy in the center, so check for doneness a few minutes before the timer goes off.
Sticky Batter: If the batter is too sticky, it might be due to overmixing or incorrect measurements. Always measure accurately and mix just until combined.
- Peanut Butter Overflow: Ensure you seal the peanut butter filling well with brownie batter to prevent it from overflowing.
- Cooling Time: Letting them cool too long in the pan can lead to sticking. Transfer them to a wire rack after a few minutes.
Prep Ahead & Store
These Brownie Peanut Butter Cups can be made in advance, making them a perfect treat for busy days.
Store them in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week. If you want to keep them longer, they freeze beautifully. Just wrap each cup individually and place them in a freezer-safe bag. Thaw in the refrigerator before serving.
Quick Questions
Can I use natural peanut butter?
Yes, but natural peanut butter can have a different texture and may cause the filling to be less creamy. It’s best to stick with creamy peanut butter for a smooth filling.
What can I substitute for all-purpose flour?
You can use a gluten-free flour blend if you need a gluten-free option. Just ensure it’s a 1:1 substitute.
Can I make these ahead of time for a party?
Absolutely! These Brownie Peanut Butter Cups can be made a day or two in advance. Just store them properly to keep them fresh.
How do I know when they are done baking?
The tops should look set and a toothpick inserted into the brownie (avoiding the peanut butter center) should come out mostly clean.
