Peanut Butter Cup Brownies

Peanut Butter Cup Brownies are fudgy and delicious, filled with miniature Reese’s Peanut Butter Cups for a decadent treat.

I am a huge fan of peanut butter cups and everyone goes crazy for Peanut Butter Cup Cookies,  No Bake Peanut Butter Cheesecake and Peanut Butter Cup Fudge. These brownies are guaranteed to please the peanut butter lovers on your list. 

Everyone needs a short cut recipe every now and again and as much as I love my homemade Walnut Brownies, I always have brownie mixes on hand. I had a some miniature peanut butter cups on hand and thought they made the very best addition to fudgy brownies!

Ingredients for Doctored Brownie Mix

• Triple Chocolate Brownie Mix ~ I’m using Hershey’s that I order from Sam’s Club, they come 4 to a box and I’m using one mix for this recipe. Use your favorite.
• Eggs ~ Room temperature eggs are best for baking.
• Butter ~ I use softened salted butter, oil is what the box calls for. Either will work.
• Water ~ I also like to use leftover coffee in place of the water.
• Reese’s Peanut Butter Cups ~ Any size will work, I sliced the miniatures in half.

How to Make Peanut Butter Cup Brownies

1. Add brownie mix to a large mixing bowl with butter, water and eggs.

2. Beat about 2 minutes, scraping down the sides about half way through until well combined.

3. Line a baking dish 8 x 8 or 8 x 11 inches with parchment paper or spray with non stick cooking spray.
4. Pour brownie batter into dish and spread brownie batter evenly.

5. Unwrap peanut butter cups and slice in half.

6. Press peanut butter cups down into the brownie batter, leaving the tops showing.
7. Bake brownies for 40 minutes, turning the pan half way through baking.

8. Remove from oven to a wire rack to cool for about 30 minutes.

9. Gently remove the parchment paper and place onto a wire rack to cool completely before slicing.

Recipe Variations

• Chips: Stir in peanut butter chips or chocolate chips – semi-sweet or dark chocolate.
• Homemade Brownies: If you don’t have a box brownie mix, this is my favorite homemade brownie recipe that uses cocoa powder, chocolate chips, flour and sugar in place of the boxed mix.

How to Store Brownies

• Store cooled brownies in an air tight container for up to 4 days. Brownies will stay fresher if they are uncut.
• Freeze brownies in a vacuum sealed bag or 2 layers of plastic wrap and a layer of foil for up to 3 months. Be sure to label with contents and the date.

BEST TOOLS FOR MAKING BROWNIES

• Stand Mixer or Hand Mixer ~ I have both and use them equally. The hand mixer works great for brownies.
• Egg Tray ~ I love this cute egg tray, so handy for letting my eggs come to room temperature for baking.
• Analon Square Baking Pan or a Casserole Dish are my favorites for brownies.
• Brownie Spatula ~ One of the handiest spatulas, perfect for desserts.

More Perfect Brownies Desserts to Try

• Brownie Pudding Pie is one of my most requested recipes. It’s a layer of fudgy brownies topped with chocolate pudding and whipped cream. It’s incredibly rich and delicious for a serious double dose of chocolate.
• Chocolate Glazed Brownies are reminiscent of the lunch room brownies we all loved as kids. A super simple recipe with the best chocolate glaze for any chocolate lover. Dress them up with festive sprinkles for a great holiday chocolate treat.
• Dr Pepper Brownies are so easy to make from scratch. A quick and easy recipe using pantry ingredients for a favorite brownie recipe that is so easy to make.

These Peanut Butter Cup Brownies are quick and easy to make, just perfect for every occasion. Delicious enough for holidays and celebrations and simple to make any day of the week with a box mix and pb cups.
