Snicker Blondies

I made these tonight for our family's New Year's Eve party. They were a hit!

1/2 Cup plus 2 tbs butter (room temp)
2 Cups brown sugar
2 eggs (room temp)
1 1/2 tsp vanilla
2 cups flour
1 1/2 tsp baking powder
1/2 tsp salt
6 miniature Snickers bars, cut into pieces

Place butter, brown sugar in mixing bowl, blend until creamed together. Add the eggs one at a time, mix after each addition. Scrape the bowl and mix in vanilla. Put all dry ingredients in a bowl mix together. Add one cup of the dry mixture to the wet mixture, beat until incorporated. Scrap sides and add the final cup of dry mixture until blended in well. With spatula fold in Snickers pieces just until combined. Press dough into 13x9x2 inch greased and floured pan. Bake at 350 for 20-25 minutes. Cool in pan then cut into bars.
