Mostly Basic Ingredients


- Cake flour: Creates a more tender, delicate crumb than all-purpose flour.
- Pantry staples: Baking powder, salt, vanilla extract, and sugar. You could also use vanilla bean paste for a more intense vanilla flavor.
- Dairy: Whole milk, sour cream, and unsalted butter. These add fat and flavor since we’re using egg whites instead of whole eggs.
- Egg whites: Give the cupcakes a tender texture while keeping them light.
- Frosting: Butter, powdered sugar, salt, vanilla, and heavy cream.
How To Make Moist Cupcakes
Step One: Mix the Dry Ingredients
Whisk together the flour, baking powder, and salt in a bowl. This makes sure everything is evenly distributed for a light, fluffy texture.
Step Two: Combine the Wet Ingredients
In a separate bowl, whisk the egg whites, sour cream, and vanilla until smooth. This mixture adds moisture and richness to the cupcakes.

Step Three: Cream the Butter and Sugar
Using a stand mixer, beat the butter and sugar together until light and fluffy, scrape down the sides as needed.

Step Four: Combine Wet and Dry Ingredients
Alternate adding the dry ingredients and milk mixture to the butter mixture, stirring gently until just combined. Don’t over mix.

Step Five: Bake and Cool
Scoop or spoon the batter into muffin tins with cupcake liners and bake until the tops are lightly golden and a toothpick comes out clean. Let them cool for a few minutes in the pan, then transfer to a rack to cool completely before frosting.


Step Six: Make the Frosting
Beat the butter until creamy, then mix in the vanilla and powdered sugar. Add cream a little at a time until you get a smooth, fluffy consistency.


Troubleshooting and Tips
- Cake flour: Not everyone has this in their pantry, and that’s okay! You can easily swap in all-purpose flour instead, but with a small tweak. If using all-purpose flour, try replacing a small portion with cornstarch to mimic the lightness of cake flour. Sift the dry ingredients together to keep the batter smooth and fluffy.
- Piping: Use a piping bag fitted with any kind of tip you like to pipe the frosting onto the cupcakes. Make sure to chill the frosting in the fridge before piping so it holds up.
- Frosting: If the frosting is too runny, add a little more powdered sugar to thicken it. If it’s too thick, mix in a splash of heavy cream until it reaches a smooth, spreadable consistency.
- Room temperature ingredients: Using room temperature ingredients can help them blend more easily and reduce lumps. If you’re in a hurry, you can soften butter quickly.
