Rhubarb Coffee Cake

In April I visited the Skagit Valley Tulip festival and after I walked through the beautiful tulip fields I stopped at a fresh road stand market in the valley on my way back home. They had fresh rhubarb from their fields available so I decided to buy some to take home. I ended up making a Rhubarb Coffee Cake.

I'll admit that I had never used rhubarb in my kitchen before but was pleased with the lovely color and result.

Rhubarb Coffee Cake

Filling:

• 3/4 cup sugar
• 1/3 cup cornstarch
• 4 cups fresh washed and chopped rhubarb
• 2 tablespoons fresh squeezed lemon juice

Optional: 

You can add 1 cup fresh blueberries and 1 cup fresh strawberries or 2 cups fresh strawberries and then cut down on the rhubarb to 2 cups.

Cake:

• 3 cups flour
• 1 cup sugar
• 1 teaspoon baking powder
• 1 teaspoon baking soda
• 1 cup cold butter
• 2 eggs
• 1 cup buttermilk (I used powdered buttermilk mix)
• 1 teaspoon vanilla

Topping:

• 3/4 cup sugar
• 1/4 cup flour
• 1/4 cup quick cooking oatmeal

• 1/4 cup cold butter

For the filling:

1. Combine the sugar and cornstarch in a sauce pot and add in the rhubarb. 
2. Cook over medium heat until the sugar and cornstarch dissolves with the liquid that is extracted from cooking the rhubarb. 
3. Cook for at least 2 minutes. This helps the cornstarch break down. 
4. Remove from heat and add the lemon juice. Allow to cool.

Preheat oven to 350 degrees and prepare a 9 x 13 baking pan by lightly greasing it.

Method for Cake and Topping:

1. Combine flour, sugar, baking powder and baking soda together in bowl.
2. Cut in the butter.
3. Beat eggs, buttermilk and vanilla in small bowl and add to the the other ingredients until moistened.
4. Put 2/3 of this batter into prepared pan.
5. Spread the filling on top of this layer.
6. Add the remaining batter on top spreading it as evenly as you can. Don't worry if you can't cover it all. Also the batter will be sticky to deal. You can grease your fingers with a little butter to help spread the batter.
7. In a small bowl combine the dry topping ingredients.
8. Cut in the butter until crumbly.
9. Spread the topping over the top of the last layer of batter as evenly as possible. 
10. Bake in preheated oven for 50 minutes or until tester comes out clean and top begins to become golden brown. Ovens vary, so check after 45 minutes and don't worry if it takes longer than 50 minutes.
