If it’s been awhile since you’ve checked in with God, I encourage you to reach out to Him. He is waiting to hear from you!

God promises to work everything together for good.

Rhubarb Streusel Cake with Warm Vanilla Sauce

Preheat oven to 350 degrees. Spray a 9 x 9 pan with non-stick spray and set aside.

In a large bowl, cream together 2 tbsp softened butter and 1 cup sugar. Beat in 1 egg.

In a small bowl, whisk together 2 cups flour, 1 tsp baking powder, and 1/2 tsp baking soda. Pour into the creamed butter and sugar. Pour in 1 cup buttermilk and beat together until just combined.

Fold in 2 cups chopped rhubarb.

Spread batter evenly into the pan.

In a small bowl, make the streusel by mixing together 1/2 cup flour, 1/2 cup sugar, and 4 tbsp melted butter until crumbs form. Sprinkle evenly over the batter.

Bake for 40-45 minutes, or until a toothpick inserted into the center comes out clean.

Make the sauce by melting 1/2 cup butter in a saucepan over medium heat. Add in 3/4 cup sugar, 1/2 cup evaporated milk, and 1 tsp vanilla. Bring to a boil and stir constantly until slightly thickened.

Remove from heat and serve warm over the cake.
