The only thing I usually don’t have on hand is the mini peanut butter cups because I mean honestly, who can resist those little guys? The question is, who gets to them first, me or my kids?

So, to make this recipe from scratch you’ll need the following:

• 1 ½ cups milk chocolate chips
• 3 tablespoons vegetable oil
• ½ cup granulated sugar
• ½ cup all-purpose flour
• ¼ teaspoon baking soda 
• ¼ teaspoon salt
• 2 eggs, room temperature
• 2 tablespoons whole milk
• 1 teaspoon of vanilla extract
• ½ cup chopped peanut butter cups

How To Make Peanut Butter Brownies

In a heat-safe bowl, microwave the chocolate chips and the oil.
PRO-TIP: For best results microwave for 45 seconds. Stir the chips and oil, return to the microwave, and heat for another 10 seconds. Stir until the chips and oil are smooth.

In a medium-size bowl, whisk together the flour, granulated sugar, baking soda, and salt.

In a small bowl, whisk together the eggs, vanilla extract and milk. Add to the flour mixture. Now add the melted chips and stir until the batter is just combined.
PRO-TIP: Let the chocolate chip mixture cool before adding it to the egg mixture. Otherwise it will seize up.

Toss the chopped peanut butter cups with 1 tablespoon of flour.

Fold the coated chopped peanut butter cups into the batter. Mix just until all ingredients are combined.
IF USING A BOXED BROWNIE MIX: If you want to use a boxed mix, prepare it according to the directions on the box and follow along the recipe starting here!

Pour the batter into the prepared baking dish.

Using a 1 – 1 ½ tablespoon cookie scoop, or a regular tablespoon, dollop the peanut butter on top of the brownie batter.

Use a knife to swirl the peanut butter.

Bake for 30 minutes. Allow the brownies to completely cool before cutting.
