Peanut Butter Cup Brownies

Peanut Butter Cup Brownies
I took these decadent Peanut Butter Cup Brownies to a Relief Society Service Auction tonight.

Amazingly, they went for 200 service points. They are literally too rich for my blood, but if you like dark chocolate and peanut butter cups, this recipe for Peanut Butter Cup Brownies is for you.

Peanut Butter Cup Brownies

Preheat the oven and melt butter and chocolate together.
Line a9×13″ pan with foil.  Combine eggs, sugars, salt and vanilla extract.  In a separate bowl combine flour and baking powder.  Sift into the batter and fold together.  Pour batter into the pan and press the peanut butter cups into the batter.  Sprinkle batter with peanuts.
Now add the milk chocolate chips and pop it into the oven.  Bake for 34 minutes or until it passes the toothpick test, coming out clean.  Cool the brownies for 30 minutes and then refrigerate for 7-8 hours or overnight.   Remove the slab of brownies from the pan and place on a cutting board.
Cut into 24 servings and share the love.

Peanut Butter Cup Brownies
Serves: 2 dozen brownies
  • 11 ounces miniature peanut butter cups
  • 12 ounces unsalted butter
  • 4-1/2 ounces unsweetened baking chocolate
  • 9 ounces 60 percent cocoa bittersweet chocolate chips
  • 6 large eggs, room temperature
  • 1-1/4 cups granulated sugar
  • 1-1/2 cups light brown sugar
  • 1 teaspoon salt
  • 2 teaspoons pure vanilla extract
  • 1½ cups all-purpose bleached flour
  • ¾ teaspoon baking powder
  • 2 tablespoons coarsely chopped salted peanuts
  • ½ cup milk chocolate chips
  • Non-stick spray for pan
  1. Unwrap peanut butter cups. Set aside.
  2. Cut butter sticks into one-inch slices. In a small heavy saucepan, begin to melt the butter pieces over the lowest setting.
  3. While butter is melting, chop the unsweetened chocolate into ¼-inch pieces; add to the melting butter along with 9 ounces of the bittersweet chips. Use a small whisk to stir occasionally to speed melting process. When chocolate is melted and completely smooth, turn off the heat but leave saucepan on the burner while proceeding with recipe.
  4. Set a rack in the middle level of the oven and preheat to 350 degrees F.
  5. Grease a 9 by 13 by 2-inch baking pan. Line with heavy duty aluminum foil* (shiny side up) so it comes halfway up the sides of the pan and extends 1-inch beyond two ends of the pan. Grease foil in pan.
  6. Lightly whisk eggs by hand in mixing bowl.
  7. Place granulated sugar, light brown sugar and salt in a separate medium bowl; whisk into eggs until just incorporated.
  8. Gradually whisk in melted butter/chocolate mixture until just combined, then briefly whisk in the vanilla extract. Remove whisk from bowl.
  9. Place flour and baking powder in medium bowl; whisk together to combine. Sift through a medium strainer directly onto batter. Fold in with a silicone spatula until just combined. Pour batter into prepared pan and spread evenly with a small offset spatula.
  10. Push the peanut butter cups into the top of the brownie batter; do not put any within ½-inch of the pan sides.
  11. Sprinkle the chopped peanuts evenly over the batter, then place milk chocolate chips evenly on the batter.
  12. Bake for 34 minutes or until a toothpick inserted in the center comes out clean. Transfer pan to a cooling rack and cool at room temperature for 30 minutes, then refrigerate for 7 to 8 hours (or overnight.)
  13. To remove slab, run a thin knife between the foil and the sides of the pan, then remove chilled brownie slab from pan; peel off and discard foil. Place brownie slab on a cutting board. Use a long chef's knife to cut into squares or bars.
  14. * I used non-stick foil and it worked like a charm!

 For the auction, along with my Peanut Butter Cup Brownies, I asked my guy if he’d give a private dance lesson.  I won an EFT Session and the cutest blue and orange “Bronco dog” neck pillow.  Thanks Lucy and Lisa…and all the gals who pulled off a delightful evening.

    I can picture the bids going up like firecrackers the minute they found out who made the brownies. Bet your reputation preceded them.

    Of course, the fact that they looked delicious might have had something to do with it.
