Chocolate-Chip Peanut Butter Bars

You know me, I'm all about easy.  Well, the other day I was looking for something easy to make with the ingredients I had laying around the kitchen.  I found this awesome recipe and then tweaked it to fit.  So, I bring you my most awesome recipe for...

Chocolate-Chip Peanut Butter Bars

1/2 cup margarine (softened)
1 1/4 cups light brown sugar (packed)
1 egg
1 teaspoon vanilla
3/4 cup creamy peanut butter
1 3/4 cups all purpose flour
1/2 teaspoon salt
1/2 teaspoon baking soda
3 Tablespoons milk
1/2 bag dark chocolate chips
1/2 bag semi-sweet chocolate chips

Preheat oven to 375F (190C).  Grease one 9x13" cake pan.

Cream together margarine and brown sugar.  Mix in egg until thoroughly combined.  Add in vanilla.  Stir in peanut butter until smooth.  In a separate bowl, sift together flour, salt, and baking soda.  Add about half the dry mixture to the wet mixture, stir until just combined.  Dribble in about half the milk and stir until combined.  Repeat last two steps with remaining dry mixture and milk.  Stir in chocolate chips.  Press dough into the pan until it's fairly even.  Bake for 20-30 minutes or until a toothpick inserted into the center (but not through a chocolate chip) comes out clean.  Slice into bars of whatever size you like best.  One pan for me made 12 bar cookies.  Serve warm with ice cream or just eat 'em right out of whatever airtight container you keep them in.
