Notes

Recipe copyright The Domestic Spoon. For educational or personal use only. 
  1. White Cake Mix: This recipe uses boxed cake mix as a good start. Make sure to check the weight of your box! We are shooting for something that is 15.25 oz
  2. All-Purpose Flour: You could also use cake flour
  3. Sour Cream: The sour cream we add to these cupcakes succeeds in making them even more moist and rich!
  4. Egg Whites: Using egg yolks would give the cake a slightly yellow tint. Using only egg whites keeps the cake a picture perfect white
  5. Unsalted Butter: Give it a chance to get to room temperature before mixing
  6. Heavy Whipping Cream: You could substitute milk but heavy cream will give your frosting the most perfect texture and a light silky smooth feel
  7. I purchased these pearl sprinkles off Amazon for a classic and beautiful white look.
  8. Wedding cake is often flavored with almond extract but it’s one of those things you either love or hate. My best tip with almond extract is to never use too much. If you want to add some almond extract to your cupcakes, try adding just a ¼ teaspoon so the flavor does not overpower the flavor of the vanilla
  9. Full fat sour cream works best in this recipe. You could substitute it with plain Greek yogurt for a slightly healthier option.
  10. These cupcakes don’t rise too much and that’s good. You don’t want them to rise over the top of the muffin tin like muffins. This allows you to leave room for frosting.
  11. An ice cream scoop is the perfect tool for filling each cupcake tin with the perfect amount of batter.
  12. This recipe is for a very simple white buttercream frosting but you could dress up these moist white cupcakes with white chocolate frosting.
