Preparation Guide for a Fun Lunchbox Cake
Warm Up the Oven
Fire up your oven to exactly 350F. Grab a 9×13 inch baking pan and give it a quick spray of cooking oil or a light butter rub to prevent sticking.
Cream Butter and Sugar
Grab your electric mixer and whip together 1/2 cup softened butter with 1 cup sugar until the mixture turns light and fluffy. This usually takes about 2-3 minutes on medium speed.
Add Wet Ingredients
Drop in 3 whole eggs and 1 teaspoon vanilla extract. Beat the mixture until everything blends smoothly and looks completely combined.
Prepare Dry Ingredients
In a separate bowl, combine your dry ingredients:
Whisk these together until they’re well mixed and no lumps remain.
Combine Wet and Dry
Slowly add your dry ingredient mix to the wet mixture. Pour in 1 cup of milk, alternating between dry ingredients and milk. Stir gently until just combined – don’t overmix or your cake might turn tough.
Pour and Spread
Transfer the batter to your prepared baking pan. Use a spatula to spread it evenly across the surface, making sure it reaches all corners.
Bake the Cake
Slide the pan into the preheated oven. Bake at 350F for 30-35 minutes. Check doneness by inserting a toothpick in the center – it should come out clean with no wet batter clinging to it.
Cool and Serve
Pull the cake out and let it rest on a cooling rack for about 15 minutes. This helps it set and makes slicing easier. Slice into squares and enjoy!
