One recipe for blueberry cake is the double blueberry cake recipe. The main ingredients in the double blueberry cake recipe are blueberry jam, fresh or frozen blueberries, flour, sugar and milk.
To make one double blueberry cake, grease and flour either a small, 6-cup bundt cake pan or a 9-inch round cake pan. Preheat the oven to 350 degrees F. Combine 1 3/4 all-purpose flour, 3/4 cup granulated sugar, two teaspoons baking powder, 1/4 teaspoon salt, a dash of nutmeg and 1/2 teaspoon cinnamon all together in a bowl. Add clean blueberries.
Whisk two large eggs together in a separate mixing bowl with 1/2 cup blueberry jam, 2/3 cup milk, 1 1/2 teaspoons vanilla extract and five tablespoons of melted butter. Whisk everything until blended, and then add the dry ingredients and blend well. Spoon everything into the pan and bake for 30 to 45 minutes. The cake is finished when a cake tester or toothpick is inserted into the center and comes out clean.
Blueberry cake can be served alone or with frosting, such as vanilla frosting. To make vanilla frosting for the cake, combine four cups confectioner's sugar, 1/3 cup plain unsweetened yogurt, one tablespoon of hot water and one teaspoon of vanilla extract together in a mixing bowl. Mix with an electric mixer for a few minutes until creamy. The frosting can be used immediately.
