Ingredients
1 box cake mix (any flavor)
1 cup whole milk (instead of water)
1/2 cup melted butter (instead of oil)
4 large eggs (add 1 extra egg yolk)
1/2 cup sour cream or full-fat yogurt
1 tsp pure vanilla extract (or almond/lemon as needed)
Optional: 1 small box instant pudding mix, mix-ins like nuts or chocolate chips
Instructions
1. Preheat oven as directed on the box.
2. Grease and flour your cake pans or line with parchment.
3. In a large bowl, combine the cake mix, milk, melted butter, eggs, and sour cream.
4. Add vanilla extract and pudding mix if using.
5. Mix gently on low speed until smooth, about 2 minutes.
6. Fold in any optional mix-ins.
7. Pour into prepared pans and bake as directed, checking doneness with a toothpick.
8. Cool completely before frosting.
Notes
Use room-temperature ingredients for a smoother batter.
Brush baked layers with simple syrup to lock in moisture.
Finish with homemade buttercream or ganache for a bakery-style finish.
