Why You'll Love This Recipe
- This a great recipe for those peanut butter lovers that a little chocolate craving, too!
- One of my favorite desserts to go with a tall glass of cold milk!
- Fudgy chocolate brownies with a smooth peanut butter layer and chocolate ganache are better than peanut butter cups any day!
Ingredient Notes and Substitutions
- Peanut Butter - You'll want to use creamy peanut butter for this recipe. Crunchy peanut butter doesn't work well. Natural peanut butter is fine.
- Brownie Mix - Use your favorite mix that makes a 9x13 pan of chewy brownies. You'll be following the instructions and ingredients required on the box to prepare them. Trust me, no one will know that these aren't really "homemade" fudgy brownies.
- Olive Oil, Water & Eggs - These are the ingredients required for the Betty Crocker box mix I chose to use.
- Chocolate Chips - Whether you use milk chocolate chips or semi-sweet chocolate chips is up to you. Semisweet chips do cause the chocolate ganache to set up firmer, which I think is a plus.
Couple Things You'll Need
Step by Step Instructions
- Whether you use a glass 9x13 or a metal pan for this recipe is up to you.

- Cool the baked brownies completely before proceeding to the peanut butter layer.
- In a large mixing bowl, beat the room-temperature butter and creamy peanut butter well.
- Beat in ยผ cup of the instant pudding mix. Save the rest of the pudding mix for when you make this recipe again!
- Beat in half the powdered sugar at a time to keep it from flying out everywhere.
- Add the milk and beat well.
- Spread the peanut butter mixture over the top of the brownies in a smooth, even layer.
- Pop in the fridge to begin chilling while you make the ganache topping.

- Heat in the microwave carefully, in increments, until the melted chocolate mixture is perfectly smooth.
- Spread the chocolate ganache evenly over the delicious peanut butter filling layer.
- Put the dessert back in the fridge and chill for at least 4 hours.
- Cut into squares using a sharp knife.
- Running the knife under hot water and quickly but carefully drying it between cuts makes clean cuts.
- Store in the fridge in an airtight container.
