- 2 large eggs + 1 egg yolk, room temp
- 1 tbsp vanilla bean paste****

Instructions
Vanilla Cupcakes
- Preheat the oven to 350F and line a cupcake pan with 12 liners and a second pan with 3 liners (this recipe makes 15 cupcakes).
- In a large bowl using a hand or stand mixer with the paddle attachment, combine the flour, sugar, milk powder, baking powder, baking soda, and salt.
- Add the softened butter and oil and mix on medium-low speed until everything is well combined and no visible lumps of butter remain, although the mixture itself should appear lumpy.
- In a 2 cup measuring glass, beat together the water, vinegar, and sour cream until smooth.
- Then beat in the eggs and vanilla.
- With the mixer running on medium-low speed, slowly pour in the wet ingredients. Pause pouring after about 1/2 cup is added to give the batter a chance to smooth out, then continue pouring.
- The batter should appear rather thin and it’s ok if there are a few small lumps. Use a rubber spatula to give the batter one more good mix by hand, scraping down the sides and bottom of the bowl.
- Distributive the batter between the liners, filling each just a hair past halfway. Use a large cookie scoop to make this much easier!
- Bake for 15 minutes then test for doneness. A toothpick should come out clean with a few moist crumbs. If they’re not done, bake for 1-2 additional minutes.
- Very carefully (since the pan and cupcakes are still hot) immediately transfer the cupcakes to a cooling rack. Removing the cakes right away prevents any residual heat from continuing to heat the cupcakes.
- Transfer the cupcakes to the refrigerator to cool for about 30 minutes, then make the frosting.
Vanilla Bean Buttercream
- Using a hand or stand mixer with the paddle attachment, mix the butter until smooth.
- Mix in 1 cup of powdered sugar at a time. To ensure the right amount, spoon the sugar into a measuring cup and level it off. We want light and airy cups of powdered sugar.
- When the buttercream starts to become dry and thick, add a tablespoon of milk in between cups.
- After all the cups are mixed in and you’ve reached 3 tablespoons of milk, mix in the vanilla bean paste and then assess the consistency.
- The buttercream should be glossy and smooth but thick and pipable. If it’s still too thick, add in that last tablespoon of milk. If it’s too thin, mix in a heaping spoonful of powdered sugar at a time until you reach the right consistency.
- When the cupcakes are completely cooled, spread or pipe the frosting on top. Sprinkle with any topping of your choice and enjoy!

*DIY CAKE FLOUR – You can also make cake flour from all purpose flour if you can’t find cake flour at your grocery store. Measure out 1 1/2 cups of flour (192g), and then remove three tablespoons. Replace with 2 tablespoons of cornstarch and whisk to combine.
**SPOON & LEVEL – Never scoop directly from the flour as this will pack the flour down into the cup. For true, weigh the ingredients with a food scale. If that’s not an option, spoon the flour into a measuring cup and level it off with a flat edge. Don’t shake it or pack it down as we want a light and fluffy cup of flour!Â
***MILK POWDER – Milk powder is essentially just pure condensed protein. This provides an extra lift to these cupcakes while also creating a more tender crumb and well rounded flavor. It can be found in most grocery stores usually in the baking aisle. Grab a bag and add a tablespoon to any dessert recipe and watch the magic happen!
****VANILLA BEAN PASTE – Pure vanilla extract can be used instead, but I love the flavor of vanilla beans here!
