Peanut butter blondies

As soon as I saw this recipe from Bakerella I bookmarked it for the premiere of our Bachelor watch party.  They were a HUGE hit, and I know I'll be making them again!  

PEANUT BUTTER BLONDIES

Ingredients:

1 1/2 cups all purpose flour
1 teaspoon baking powder
1/4 teaspoon salt
6 Tablespoons butter, softened
1/2 cup peanut butter
2/3 cup sugar
2/3 cup packed brown sugar
3 eggs
1 teaspoon vanilla
1 cup chips (I used 1/2 cup semi-sweet and 1/2 cup peanut butter chips; lots of combinations would be great in these!)

Instructions:

Preheat oven to 350 degrees and grease 9 x 9 pan

In a medium bowl, stir the flour, baking powder and salt together with a wire whisk and set aside.

In a mixer, cream the butter and peanut butter until smooth. Add the sugars and mix until combined.

Add the eggs and vanilla and mix until combined.  Add the dry ingredients and mix on low until combined.  Stir in the chips.

Spread in the pan and bake for 30-35 minutes* or until done.

* I baked mine for 32 minutes in a convection oven.  They were quickly browning on the top, so I covered them with foil for the last 10 minutes.  Adjust your time according to size of pan you use, and whether you're using convection or conventional oven.  These blondies are thick, so a 9x13 pan should work as well if you decrease the baking time accordingly.
