2 tbsp. plus 2 tsp. firmly packed dark brown sugar
1/2 c. chunky style peanut butter
1 tsp. vanilla extract
1/2 tsp. ground cinnamon

Preheat oven to 350 degrees. Onto sheet of wax paper or a paper plate sift together flour and baking powder; set aside.

In medium mixing bowl combine egg and sugar and, using an electric mixer, beat until thick; add peanut butter, vanilla, and cinnamon and beat until combined. Add sifted flour alternately with milk, about 1/3 at a time, beating after each addition; stir in apple.
