Step 1: Prepare the Pan: Preheat oven to 350F (175C). Do not grease the tube pan. The cake needs to cling to the sides to rise properly. An ungreased aluminum tube pan (9- or 10-inch) with a removable bottom is essential.
Step 2: Combine Mix and Water: In a large bowl, whisk together the angel food cake mix and cold water until well combined. If using, stir in the vanilla extract at this stage. Ensure there are no large lumps remaining. Overmixing can deflate the egg whites, so mix gently but thoroughly.
Step 3: Pour into Pan: Gently pour the batter into the ungreased tube pan. Use a spatula to spread the batter evenly, but avoid pressing down.
Step 4: Bake: Bake in the preheated oven for 35-45 minutes, or until the top is lightly golden brown and the cake springs back when lightly touched. A toothpick inserted near the center should come out clean. Note that baking times may vary depending on the oven, and the status of the mix being used.
Step 5: Invert and Cool: Immediately after removing the cake from the oven, invert the pan onto a heatproof bottle or the pan's legs (if equipped). Allow the cake to cool completely upside down, typically for at least 1-2 hours. This prevents the cake from collapsing.
Step 6: Remove from Pan: Once cooled, run a thin knife or spatula around the edges of the pan to loosen the cake. Gently push the cake upwards from the bottom of the pan, if it has a removable base, or invert it carefully onto a serving plate.
Step 7: Serve: Dust with powdered sugar, top with fresh berries, or serve with whipped cream. Enjoy!
Optional Tips:
Flavor Boost: Enhance the flavor with a teaspoon of almond extract or lemon zest.
Texture Improvement: If concerned about the leavening power of the mix, add 1 teaspoon of baking powder to the dry mix before adding water.
* Serving Suggestions: Pairs exceptionally well with a light lemon curd or a fruit compote.
