Lithuanian Coffee Cake

Adapted from a recipe in Claire's Corner Copia Cookbook. This recipe went over rather well with some friends of mine. It makes either bundt cake or muffins, depending on what you'd like.

1 1/2 sticks butter
3 eggs
2 cups sugar
2 tsps vanilla
3 cups flour (I like the whole wheat kind, it gives it some body)
2 tsps baking powder
1 cup brown sugar (for topping)
2 cups buttermilk
1 cup leftover coffee
3 - 5 tbs. cinnamon

If you like, add raisins, walnuts, etc.

Mix dry ingredients in bowl until all components evenly distributed in dry mix. Melt butter, add melted butter to mix. Add eggs, vanilla, and buttermilk. Stir thoroughly. Batter will be dry and pebbly. Slowly add the coffee until the batter loses its dry stickiness, stop when the batter becomes easy to stir. Put batter in heavily greased bundt pan or in prepared cupcake tins. Bake on 350 for one hour (bundt cake) or 40 minutes (muffins). Dust with brown sugar shortly after taking them out of the oven.
