Ingredients
Cupcakes:
- 1 2/3 cups (217g) all-purpose flour
- 1 teaspoon baking powder
- 1/4 teaspoon baking soda
- 1/2 teaspoon salt
- 3/4 cup (168g) unsalted butter, melted
- 1 cup (207g) granulated sugar
- 2 teaspoons vanilla extract
- 2 large eggs
- 1/2 cup (115g) sour cream
- 1/4 cup + 2 tablespoons (100ml) milk
- 1 1/2 cups (200g) chopped fresh strawberries
Strawberry Buttercream Frosting:
- 1 1/2 cups (200g) chopped fresh strawberries
- 1 1/4 cups (280g) unsalted butter, room temperature
- 5 cups (575g) powdered sugar
- 1/2 teaspoon vanilla extract
- Pinch of salt
- Fresh strawberry slices for garnish
Preparation Notes:
- Ensure all dairy ingredients and eggs are at room temperature to promote smooth mixing and better cupcake texture.
- Wash and pat dry fresh strawberries before chopping to remove excess moisture but keep the strawberries fresh.
- Use ripe, fragrant strawberries for the best flavor; avoid overripe or mushy berries.
Instructions
1. Preheat your oven and prepare the pan:
Set the oven to 350°F (176°C). Line a standard 12-cup muffin tin with cupcake liners.
2. Mix dry ingredients:
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt until well combined. This ensures even rising and seasoning.
3. Combine wet ingredients:
In a large bowl, whisk the melted butter, granulated sugar, and vanilla extract until smooth. Add eggs one at a time, beating well after each addition. Then stir in sour cream and milk until the mixture is fully blended.
4. Incorporate dry ingredients into wet:
Gradually add the dry flour mixture to the wet ingredients. Use a spatula or wooden spoon to fold gently until just combined. Avoid overmixing to prevent dense cupcakes.
5. Add the chopped strawberries:
Carefully fold in the fresh strawberries. Mix just enough to distribute them evenly without breaking down the fruit.
6. Fill cupcake liners:
Spoon the batter into the prepared liners, filling each about two-thirds full to allow space for rising.
7. Bake:
Place the cupcake tray in the oven and bake for 18-20 minutes. Test doneness by inserting a toothpick into the center; it should come out clean or with a few moist crumbs attached.
8. Cool cupcakes:
Remove cupcakes from the oven and let them cool in the pan for 5 minutes. Then transfer them to a wire rack to cool completely before frosting.
9. Prepare the strawberry reduction for the buttercream:
Puree 1 1/2 cups chopped strawberries in a blender or food processor. Pour the puree into a small saucepan and cook over medium heat, stirring often, until the volume reduces to about 6 tablespoons (this takes 10-15 minutes). Let it cool completely.
10. Make the buttercream:
In a mixing bowl, beat the room temperature butter until creamy and smooth. Add half the powdered sugar and beat until combined. Mix in the cooled strawberry reduction, vanilla extract, and salt. Gradually add the remaining powdered sugar and continue beating until the frosting is light and spreadable.
11. Frost the cupcakes:
Once cupcakes are fully cooled, pipe or spread the strawberry buttercream on top.
12. Garnish:
Top each cupcake with a fresh strawberry slice or small strawberry piece for a pretty finishing touch.
Notes
- Room Temperature Ingredients: Always bring eggs, butter, and dairy to room temperature before baking. This helps create a smooth batter and better rise.
- Gentle Folding: When mixing in the strawberries, fold gently to prevent the fruit from bleeding color and turning the batter pink.
- Prevent Overbaking: Keep a close eye during the last few minutes of baking. Cupcakes can dry out quickly if overbaked. Toothpick tests help avoid this.
- Strawberry Reduction Cooling: Make sure the strawberry reduction is fully cooled before adding to the buttercream. Warm liquid can cause the frosting to separate or melt.
- Storage: Keep cupcakes in an airtight container. They stay fresh for 2 days at room temperature or up to a week refrigerated. Bring them back to room temperature before serving for best texture.
- Ingredient Substitutions: You can swap sour cream for Greek yogurt or buttermilk. Use whole milk or almond milk instead of regular milk if preferred.
- Adjust Sweetness: Taste the buttercream before frosting and adjust powdered sugar as needed to your preferred sweetness.
