CRUST

1 Pre-heat oven to 350 degress

2 Sift flour, baking soda, baking powder, and salt in medium bowl.

3 Mix butter until creamy, then add brown sugar beating until fluffy. Add peanut butter and mix, then add the egg and vanilla. Add dry ingredients and mix.

4 Place dough into the bottom of a 9 x 13 inch baking pan, flattening to cover the entire surface.

5 Bake for approximately 10 minutes until firm, but not fully baked.

FILLING

1 While the crust is baking, mix cream cheese, brown sugar, peanut butter and flour together until smooth. Add eggs one at a time, then milk mixing just until incorporated. Pour batter into prepared crust. Place in the oven and bake for 10 minutes, then turn the temperature to 250 and bake for 35- 40 minutes longer. The top should be firm but not brown, with a little jiggle in the center (not much though). Remove from the oven and set aside to cool.

CHOCOLATE DRIZZLE (GANACHE)

1 In a microwave safe bowl, heat the cream to just below boiling, about 1 minute. Add the chocolate and stir gently until melted and smooth. Drizzle over the top of the bars.

2 Refrigerate for several hours to overnight, then slice into small squares (it is very rich).
