Blondies

I've made these a few times when I wanted a dessert but was lacking in the chocolate department.

Blondies
1 cup butter, melted
1 cup brown sugar
1 cup sugar
4 eggs
2 t. vanilla extract
2 1/2 cup flour
1 T. baking powder
1 t. salt

In a large bowl, combine butter, brown sugar, and sugar. Beat until smooth. Stir in eggs and vanilla. Beat again. Add flour, baking powder and salt. Mix until thick and smooth. Put in greased 9x13 pan and bake at 350 for 25-30 minutes.
