To prepare a Washington Cheesecake Baked Goods recipe, first you need to prepare the ingredients for the recipe. First, you'll need the following ingredients: Preheat the oven to 350 degrees F. Line an 8x8-inch baking pan with foil and grease the foil with cooking spray. Set aside. In the bowl of an electric mixer fitted with the paddle attachment, cream together the butter and sugar until light and fluffy. Add the eggs and vanilla and beat until combined. Gradually add the flour and mix until the mixture resembles crumbled breadcrumbs. Pour the batter into the prepared pan and bake for 30 to 35 minutes or until browned and bubbly. Allow the cake to cool before removing it from the pan.
