Nutty Peanut Butter Blondies

I made these for our son, Christopher, to take back up to LA with him. Though he loved them and took half of the pan, the other half was devoured by our younger son Ryan. Two out of three children gave me the thumbs up so I count that as success.

Makes about 32 bars

2 1/2 cups flour
2 cups sugar
1 tsp baking powder
2/3 cup creamy peanut butter
1 stick of butter melted(1/2 cup)
1/4 cup lowfat milk
2 tbsp vanilla
4 large eggs
1/2 cup chocolate chips
20 mini peanut butter cups, cut in half

Preheat oven to 350. Spray a 9x13 baking pan with baking spray. In the bowl of an electric mixer, beat the butter and sugar until fluffy. Add the eggs, vanilla and peanut butter. Turn the mixer on low and add the baking powder, flour and milk. Mix the chocolate chips in by hand. Turn the batter out into the prepared pan and spread out evenly. Scatter the peanut butter cups over the top. Bake for 25-30 minutes. Cool, cut into bars and serve
