Ingredients
Scale
Vanilla Cupcakes
- 1 1/2 cups (182g) cake flour, spooned and leveled
- 1 cup (200g) granulated sugar
- 2 tbsp dry milk powder
- 1 tsp baking powder
- 1/2 tsp baking soda
- 1/4 tsp kosher salt
- 6 tbsp unsalted butter, softened
- 3 tbsp vegetable oil
- 1/4 cup warm water
- 1/2 tsp vinegar
- 1/2 cup (120g) sour cream, room temperature
- 2 large eggs + 1 egg yolk, room temperature
- 1 tbsp vanilla bean paste
Vanilla Bean Buttercream
- 1 cup (220g) unsalted butter, softened
- 6 cups (660g) powdered sugar
- 3–4 tbsp milk
- 1/2 tbsp vanilla bean paste
Instructions
- Preheat: Preheat the oven to 350°F (177°C). Line a cupcake pan with 12 liners and a second pan with 3 liners to make 15 cupcakes total.
- Mix Dry Ingredients: In a large bowl using a hand or stand mixer with paddle attachment, combine the cake flour, granulated sugar, dry milk powder, baking powder, baking soda, and kosher salt.
- Add Fats: Add the softened butter and vegetable oil to the dry ingredients. Mix on medium-low speed until fully incorporated and no lumps of butter remain, though the mixture can appear slightly lumpy.
- Prepare Wet Ingredients: In a 2-cup measuring cup, whisk together warm water, vinegar, and sour cream until smooth. Beat in the eggs and vanilla bean paste until combined.
- Combine Wet and Dry: With mixer on medium-low speed, slowly pour the wet mixture into the dry ingredients. Pause after adding about 1/2 cup of wet mix to let the batter smooth out, then continue pouring. The batter will be thin with some small lumps.
- Final Mix: Use a rubber spatula to scrape down sides and bottom of bowl and fold the batter gently for an even consistency.
- Fill Cupcake Liners: Distribute batter evenly among cupcake liners, filling each just over halfway. A large cookie scoop helps with even portioning.
- Bake: Bake for 15 minutes, then test doneness with a toothpick. It should come out clean or with a few moist crumbs. If not done, bake an additional 1-2 minutes.
- Cool: Carefully transfer cupcakes from pans to a wire rack immediately to stop residual cooking and cool completely. Once cooled, refrigerate cupcakes for about 30 minutes before frosting.
- Make Buttercream: Cream Butter: Using a mixer with paddle attachment, beat softened butter until smooth and creamy.
- Incorporate Powdered Sugar: Add powdered sugar one cup at a time, spooned and leveled for accuracy, mixing thoroughly after each addition.
- Adjust Consistency: When mixture becomes dry and thick, add 1 tablespoon of milk between sugar additions. After all sugar is incorporated and 3 tablespoons of milk added, mix in vanilla bean paste.
- Final Consistency: Assess buttercream thickness. If too thick, add the remaining 1 tablespoon milk. If too thin, add heaping spoonfuls of powdered sugar until frosting is glossy, smooth, thick, and pipeable.
- Frost Cupcakes: Once cupcakes are fully cooled, either spread or pipe vanilla bean buttercream on top.
- Serve: Optionally, sprinkle with your favorite toppings and enjoy these moist, fragrant vanilla cupcakes.
Notes
- Using cake flour helps achieve a tender crumb; do not substitute with all-purpose flour without adjustments.
- Warm water helps dissolve the dry milk powder and activates baking soda.
- Let cupcakes cool completely before frosting to prevent buttercream from melting.
- Vanilla bean paste can be substituted with high-quality vanilla extract if unavailable.
- Refrigerating cupcakes before frosting firms them and makes decorating easier.
- Store frosted cupcakes covered at room temperature for up to 2 days or refrigerated for up to 4 days.
