White Chocolate Peanut Butter Oatmeal Oreo Blondies

I found this brilliant recipe the other day and was totally smitten, and immediately set about creating my own version.  My family loves peanut butter treats, and although I'm fairly ambivalent about peanut butter, the peanut butter frosting in that recipe is one of my favorite peanut butter applications ever.  Ever.  This recipe starts with a peanut butter oatmeal Oreo blondie and is topped with a peanut butter white chocolate chip frosting.  Unbelievable.  

White Chocolate Peanut Butter Oatmeal Oreo Blondies 

Blondies:
1/4 cup (4 Tablespoons) butter, room temperature
2 Tablespoons creamy peanut butter
1/2 cup packed brown sugar
1/4 cup granulated sugar
1 egg
3/4 cup all purpose flour
3/4 cup old fashioned oats
1/2 teaspoon baking powder
1/8 teaspoon salt
1 cup chopped peanut butter Oreos (about 8 or 10 Oreos)

Peanut Butter White Chocolate Chip Frosting:
1/2 cup creamy peanut butter
1 cup powdered sugar
4 Tablespoons milk
1/2 cup white chocolate chips

Preheat the oven to 350F.  Line a 9x9 inch square baking pan with parchment paper, leaving the edges of the paper hanging over the sides to use as handles.

In a large bowl, cream together the butter and peanut butter until smooth.  Beat in the brown sugar and granulated sugar until light and fluffy.  Beat in the egg.  Add the flour, oats, baking powder, and salt, and beat until just combined.  Stir in the chopped Oreos until evenly distributed.  Spread the batter evenly in the prepared pan.  Place in the oven and bake for about 20 minutes, or until the edges are golden and a toothpick inserted in the center comes out with moist crumbs.  Remove from the oven and let cool for about 5 minutes before frosting.

While the blondies are cooling make the frosting.  In a large bowl, combine the peanut butter and powdered sugar, and beat until blended (mixture may be crumbly).  Add 2 tablespoons of the milk and beat well, then add the remaining 2 tablespoons of milk and beat until well blended and smooth.  Stir in the white chocolate chips.  Immediately spread the frosting over the warm blondies, spreading evenly.  Let cool.  Makes 16 servings.

Enjoy!  -Cardamommy
