Step 1: Inspect the Cake Mix: Prior to beginning, carefully examine the cake mix. Look for any signs of clumping, discoloration, or the presence of pests. Sniff the mix; it should have a sweet, pleasant aroma, not a musty or rancid smell. If any of these negative signs are present, discard the mix.
Step 2: Test the Leavening (Optional): To assess the leavening power of the mix, place 1 teaspoon of the dry mix into 1/4 cup of hot water. If the mixture fizzes vigorously, the leavening is likely still active. A weak fizz suggests diminished leavening power.
Step 3: Preheat the Oven: Preheat the oven to the temperature specified on the cake mix box (usually 350F/175C). Grease and flour a cake pan. Alternatively, use a baking spray with flour.
Step 4: Combine the Ingredients: In a large mixing bowl, combine the cake mix with the ingredients listed on the box (eggs, oil, and water or milk). Follow the proportions specified on the package.
Step 5: Mix the Batter: Using an electric mixer, blend the ingredients on low speed until just combined. Increase the speed to medium and mix for 2 minutes, or until the batter is smooth and well-combined. Be careful not to overmix, as this can result in a tough cake.
Step 6: Pour into Pan and Bake: Pour the batter into the prepared cake pan, spreading it evenly. Bake for the time specified on the cake mix box (usually 25-35 minutes). A toothpick inserted into the center should come out clean when the cake is done.
Step 7: Cool the Cake: Remove the cake from the oven and let it cool in the pan for 10 minutes before inverting it onto a wire rack to cool completely.
Step 8: Frost and Decorate (Optional): Once the cake is completely cool, frost it with the frosting of your choice and decorate with sprinkles, if desired.
Tips & Substitutions: For a richer flavor, substitute milk for water. Adding a teaspoon of vanilla extract can also enhance the taste. If the leavening seems weak, consider adding an extra 1/2 teaspoon of baking powder to the mix. To make a chocolate cake from a vanilla mix, add 1/4 cup of unsweetened cocoa powder.
