To prepare a strawberry ice box cake baked goods recipe, first you need to prepare the ingredients for the cake. First, you will need the following ingredients: Preheat the oven to 350?F (180?C) and grease and flour two 9x5-inch baking pans. In another bowl, mix together the flour, baking powder, sugar, salt and vanilla. Add the dry ingredients to the wet ingredients and mix until just combined. Pour the batter into the prepared pan and bake for 20 to 25 minutes or until the toothpick inserted in the center comes out clean. Let cool before removing from the pan.
