1/2 c packed brown sugar
4 TBSP butter, cut into small pieces
1/4 cup flour
2 tsp. cinnamon
2 cups flour- I used 1 1/2 white, 1/2 wheat
2 tsp baking powder
1 tsp baking soda
1/2 tsp salt
1/2 cup butter, room temp
1/2 cup sugar
1/2 c buttermilk
1 tsp vanilla
Combine alll the cinnamon ripple ingredients in a mixing bowl and use an electric mixer to blend them. Set the mixute aside. Heat oven to 400 degrees. Grease the bottom only of 12 standard muffin cups. ( I used 18 because in the past they seem to grow out of their little space.)
In a medium bowl whisk together flour, baking soda, baking powder and salt. In a large bowl beat butter and sugar with an electric mixer until pale and fluffy, then beat in eggs, buttermilk and vanilla. Stir in dry ingredients until blended. Sprinkle cinnaming rippkle over butter and fold a couple of times- you don't want it all mixed in like I did or you get to ripple effect.
Divide batter and bake 13 minutes or until toothpick comes out clean. Let cool, for 5-10 minutes before remioving them from pan.
