Quick and easy and cheap birthday cake recipe

Efficient

For a quick, budget-friendly birthday cake, the "Wacky Cake" (also known as Depression-era cake) is the best choice. It requires no eggs, butter, or milk, and you mix it directly in the pan.

The One-Pan Chocolate Wacky Cake

Ingredients:

  • 1 ½ cups all-purpose flour
  • 1 cup sugar
  • 3 tablespoons unsweetened cocoa powder
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 teaspoon white vinegar (or apple cider vinegar)
  • 1 teaspoon vanilla extract
  • 5 tablespoons vegetable oil
  • 1 cup water

Instructions:

  1. Preheat: Set your oven to 350°F (175°C).
  2. Mix: Grease an 8x8-inch square pan. Add all the dry ingredients directly into the pan and whisk them together with a fork.
  3. Make wells: Make three depressions (holes) in the dry mixture—two small ones and one larger one.
  4. Add liquids: Pour the vinegar into one small hole, the vanilla into the other, and the vegetable oil into the large hole. Pour the water over the top.
  5. Combine: Mix everything with a fork until smooth (ensure you get into the corners of the pan).
  6. Bake: Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.
  7. Cool: Let it cool completely before frosting.

Budget Toppings:

  • Simple Glaze: Whisk 1 cup of powdered sugar with 2 tablespoons of cocoa powder and 2 tablespoons of water or milk until smooth. Pour over the cooled cake.
  • Dusting: If you don't have frosting ingredients, simply dust the top with powdered sugar or cocoa powder.

This recipe is simple, relies on pantry staples, and tastes surprisingly rich for a cake made without dairy or eggs. Happy birthday!
