This is a recipe that I found a while back. It is really good and smells so wonderful first thing in the morning. I have changed the original recipe around a little bit though.

Overnight Coffee Cake (Link to original recipe)

Ingredients:

• 2/3 cup butter, softened
• 1 cup white sugar
• 2 eggs
• 2 cups all-purpose flour
• 1 teaspoon baking powder
• 1/2 teaspoon baking soda
• 1 teaspoon ground cinnamon
• 1/2 salt
• 1 cup buttermilk or sour cream, whichever I have on hand

Topping:

• 1/2 cup packed brown sugar
• 1/2 cup finely chopped walnuts or pecans, whichever I have on hand
• 1/2 t ground cinnamon

Glaze: (optional)

• 1 -1/2 c. confectioner’s sugar
• 2-3 T. milk
• 1/2 t. vanilla

Directions:

Lightly grease a 13×9 baking pan.

In a large bowl, cream together the butter and sugar. Beat in the eggs, one at a time, until well blended.

In a medium bowl, combine the flour, baking powder, baking soda, salt, and cinnamon.

Stir the flour mixture into the creamed mixture alternately with buttermilk or sour cream.

Spread evenly into the prepared baking pan.

In a small bowl, mix together the topping ingredients. Sprinkle over the batter. Cover, and refrigerate overnight.

The next day, preheat oven to 350.

Allow the cake to sit for about 30 minutes at room temperature before baking.

Bake the cake for 35 to 45 minutes in the preheated oven, or until a toothpick inserted in the center comes out clean.

Cool for 10 minutes.

Mix together the Glaze ingredients, if desired, and drizzle over the warm cake.

Grab a cup of coffee and enjoy!
