Blueberry Kuchen, also known as German Coffee Cake, is a delicious dessert to serve when you have company at your house. Perfect for a weekend brunch.

What makes it so great? It’s moist. And filled with a pint of fresh, plump blueberries. Plus, it’s topped with a crumbly oat, pecan, and sugar mixture that turns crusty as it bakes. It’s delicious to eat and it’s pretty to serve.
I like to make this cake in a coffee cake pan, but you may also use an oblong baking pan or a tube cake pan.

Instructions for Making This Recipe


Preheat oven to 350°F. Gather the ingredients so you have everything close at hand on the counter or table. Coat a 9″ square cake pan, coffee cake pan, or Bundt-style pan with shortening and flour or baking spray to cover the inside.
If I’m making this cake for a family gathering or church potluck, I may use a tube-style pan for a prettier display. I like to use Ever Bake or Baker’s Joy when working with Bundt pans. But you may also grease and flour the pan, if you prefer.
Prepare the Ingredients

Using a nut chopped or knife, coarsely chop the pecans.
If you don’t have pecans, English walnuts also work well in this recipe.
Rinse blueberries and drain in a colander. Sprinkle berries with all-purpose flour.
I like to make this cake when blueberries are at the peak of their season or when I can find them on sale at the grocery store. You may use frozen blueberries if you prefer. Just be sure to coat the berries, either fresh or frozen, in a little bit of flour. This will help them from falling to the bottom of the pan when they cook.
Make the Crumb Topping


In a small bowl combine the granulated sugar, brown sugar, old-fashioned rolled oats, chopped pecans, all-purpose flour, salt, and ground cinnamon. With a blending fork, a knife, (or your hands), cut in butter until crumbly. Set aside.
Prepare the Coffee Cake Batter


In a small bowl, combine the all-purpose flour, baking powder, baking soda, salt, ground cinnamon and nutmeg. Whisk together until thoroughly combined.


In a large mixing bowl, beat together the granulated sugar and butter until creamy, approximately 5-7 minutes. Add large eggs one at a time, along with the vanilla extract.

Add the flour to creamed mixture alternately with buttermilk. Using a rubber spatula, fold blueberries into the cake batter until incorporated.


Spread batter into the prepared baking pan, being careful not to touch the edges of the pan. Smooth a spatula evenly over the batter. Sprinkle top with the crumb topping.


Bake in preheated oven for 50-60 minutes until wooden toothpick inserted in center of cake comes out clean. Cool for 10 minutes. If using a Bundt-style pan, you may remove the cake from the pan at this time. Place cake on a serving plate. Allow to cool slightly while (about 20 minutes) you make the glaze.
Make the Glaze


In a small bowl combine powdered sugar, hot water, and vanilla extract. Mix until smooth and creamy. Drizzle glaze over slightly warm cake.

This recipe will serve 9 people. Serve Blueberry Kuchen with a dollop of fresh whipped cream and a cup of coffee.
