1 3/4 cups all purpose flour

1/2 cup brown sugar

1/2 cup sugar

1/2 tsp ground cinnamon

1 tsp baking powder

1/2 tsp baking soda

1/2 tsp salt

1/2 cup butter, room temperature

3/4 cup buttermilk

1 large egg

1 cup crunchy peanut butter, room temp. (not natural)

for jam drizzle:

1 jar of strawberry or raspberry jam/jelly (I used raspberry: seedless)

Confectioners’ sugar for decoration (optional)

Preheat oven to 350F. Lightly grease and flour an 8×8 square baking pan.  In a large bowl mix the flour, brown sugar, sugar, cinnamon, baking powder, baking soda and salt.  Using a mixer (or by hand), beat in the softened butter until mixture resembles wet sand. No large lumps. If using a mixer, do not over beat. Remove between ¾ – 1 cup of the mixture to a medium bowl and set aside. (I did about a cup since I wanted a lot of crumb topping and thin cake; just like a crumb cake).  With the remaining mixture add in the buttermilk and egg, mix well. Then pour into the greased pan, spreading evenly. There is not a lot of batter; it does rise when baking so don’t worry.  Take the remaining flour mixture that was set aside and add the cup of peanut butter to it.  Mix until you have a nice, almost dry crumbly mix.  Then drop or crumble large chunks of this onto the cake. Do not press the crumbs into the batter; just let them sit on top.  Bake for about 30 -35 minutes, until a tester inserted into the center of the cake comes out clean. While cake bakes make the jelly reduction. Take a small jar of strawberry or raspberry jam/jelly,  and let gently melt in saucepan over low heat. Do not boil. To make the reduction slightly thicker add a bit of cornstarch (a TB or so). But you shouldn’t need to do this as after it’s melted it does thicken a bit.  When slightly cooled drizzle cake with the ‘melted jam. Then dust with confectioners’ sugar if desired. Cool on a wire rack before slicing.
