1/2cupbuttermelted, I don't recommend using margarine
For the blueberry sauce, I used this Strawberry Sauce recipe and substituted blueberries.
Spray a 9x13 inch cake pan with non-stick spray.
Preheat oven to 350 degrees Fahrenheit
In the bowl of an electric mixer, combine sugar and oil. Add yogurt. Mix until combined. Add eggs and vanilla.
In another bowl, combine flour, baking powder and salt. Gradually add to wet ingredients.
Mix until smooth.
Pour into prepared pan.
Spoon 2 cups blueberries sauce over cake batter.
Combine brown sugar, granulated sugar, cinnamon, salt and flour to a bowl. Stir to combine. Add melted butter and stir to combine. The mixture will be thick and clumpy.
Crumble evenly on top of blue berries.
Bake 45 to 50 minutes at 350 degrees. Insert wooden pick in center of cake to test for doneness. Remove and allow to cool on wire rack.
Serve warm plain for brunch or with vanilla ice cream as a dessert.
