These brownies went so fast I didn't have time to get a good pic
1 cup all-purpose flour
1/4 cup light brown sugar
1/4 cup granulated sugar
1 cup peanut butter
1/4 cup melted butter
1/4 tsp. salt until blended and crumbly.
Combine the above ingredients until a soft dough forms.
Pour brownie batter into greased 9x13 pan. Take pieces of the peanut butter dough and cover brownie batter with it. (It is okay if all the brownie isn't covered. The brownie that seeps through has a really good texture!) Bake at 350 degrees 45-50 minutes.
