How to Make This Peanut Butter Brownie Recipe:

Ingredients 

• 1/2 cup melted butter
• 1 cup white sugar
• 2 large eggs
• 1 teaspoon vanilla extract
• 1/3 cup cocoa powder
• 1/2 cup all purpose flour
• 1 teaspoon salt
• 1 teaspoon baking powder
• 1 cup peanut butter chips
• 1/2 cup creamy peanut butter

Peanut Butter Frosting Ingredients:

• 1 1/2 cups white sugar
• 1/2 cup milk
• 2 Tablespoons shortening
• 2 Tablespoons unsalted butter
• 1 teaspoon salt, optional
• 1 teaspoon vanilla
• 1/2 cup peanut butter
• 1/2 cup Chocolate Chips

Directions

Pre heat oven to 350F, grease a 8″ x 8″ square pan and set aside.

In a large bowl, beat together the butter and sugar until combined.

Add the eggs and vanilla extract and beat until combined.

In a medium-sized bowl, stir together the dry ingredients: cocoa powder, flour, salt and baking powder.

Beat the flour mixture into the sugar mixture and then add the peanut butter chips.

Fold the chocolate brownie batter out into your prepared pan.

Melt the peanut butter for 15 seconds in a microwave-safe bowl.

Spoon the peanut butter mixture on top of the brownie batter.

Use a butter knife to swirl the peanut butter throughout the chocolate mixture.

Bake your chocolate peanut butter brownies for a baking time of 25-28 minutes – until the edges of the brownies are crisp and start to pull away from the pan and an inserted toothpick comes out with just a few crumbs and no wet batter.

Allow the brownies to cool completely before frosting.

While the baked brownies are cooling, prepare your peanut butter frosting.

In a large saucepan over medium-high heat, combine the sugar, milk, butter, shortening and salt.

Stir constantly until the mixture reaches a boil, then allow to boil for 2-3 minutes without stirring.

Remove the saucepan from heat and stir in the vanilla and peanut butter.

Pour the frosting over your fudgy chocolate brownies.

Scatter a small handful of chocolate chip over the hot frosting.

Let set for 2 hours or overnight before cutting and serving.

How to Reheat Brownies

Microwaving fudgy peanut butter brownies is a great way to get them warm again. Just pop them in the microwave for 30 second intervals.

If you want to get a little bit fancier, you can reheat your brownies in the oven. Preheat your oven to 350 degrees and place the brownies on a baking sheet. Bake for 5-10 minutes, or until warmed through.
