If you need a baking experiment on a rainy weekend, start with this simple cake recipe that requires only five easy-to-find ingredients: butter, sugar, eggs, flour and baking powder. This cake serves as a good foundation, and how you change up the proportions, make substitutions and add other flavorings is what creates varying flavors and recipes.
Pre-heat your oven to 350 degrees Fahrenheit.
In a mixing bowl, cream the butter and sugar together with a wire whisk until thoroughly mixed. To soften the stick of butter, warm it in the microwave for about 30 seconds.
Add the flour and baking powder and beat for another minute until the batter is smooth without any lumps.
Pour the batter into a nonstick cake pan or a regular pan that's been prepped with butter and flour. If you use an 8x8 pan, bake for 25-30 minutes, and 20-25 minutes if you use a larger pan. You'll know the cake is done when a toothpick comes out clean when you poke it in the center of the cake.
