Ingredients:
- 1.5 cups All purpose flour
- 1 cup Granulated sugar
- 1.5 tsp Baking powder
- 0.5 tsp salt
- 0.5 cup Unsalted butter
- 1 large Egg
- 0.25 cup Sour cream
- 0.5 cup Whole milk
- 2 tsp Vanilla bean paste
- 1 cup softened butter
- 3.5 cups powdered sugar, sifted
- 2.5 tbsp heavy cream
- 1 tbsp vanilla extract
- 1 pinch fine salt
Instructions:
- Put on some music, preheat your oven to 350°F, and let's get baking. This process is all about the creaming method, which is the foundation of most classic cakes.
- Whisk dry ingredients. Combine the 1.5 cups flour, 1.5 tsp baking powder, and 0.5 tsp salt in a medium bowl. Note: This ensures the leavening is evenly distributed so you don't get giant holes in your cakes.
- Cream butter and sugar. Beat 0.5 cup butter and 1 cup sugar for 3 full minutes until pale, fluffy, and significantly lightened in color.
- Incorporate the egg. Add the room temperature egg to the butter mixture. Note: If the mixture looks curdled, don't worry, it will come back together when the flour is added.
- Add flavor and fat. Mix in the 2 tsp vanilla bean paste and 0.25 cup sour cream. until the aroma of vanilla fills the air.
- Alternate liquids and solids. Add half of the flour mixture, then the 0.5 cup milk, then the remaining flour. Note: Alternating prevents the batter from becoming too thin or too lumpy.
- Fill the liners. Use a scoop to fill your cupcake liners about two thirds full. until the batter is level across the pan.
- Bake the cakes. Place in the oven for 18 to 20 minutes until the tops spring back when gently pressed.
- Prepare the buttercream. While the cakes cool, beat 1 cup softened butter with 3.5 cups powdered sugar. Note: Sift the sugar first to avoid those annoying little white lumps.
- Finish the frosting. Add 2.5 tbsp heavy cream, 1 tbsp vanilla extract, and a pinch of salt. until the frosting is velvety and holds a stiff peak.
- Frost and decorate. Wait until the cupcakes are completely cold before piping on the vanilla buttercream. until the frosting sits proudly on top without melting.
