Step‑by‑Step Instructions for Blackberry Swirl Cupcakes
Step 1: Preheat the Oven and Prepare the Tin
Begin by preheating your oven to 350°F (175°C) to ensure it’s at the perfect temperature for baking. While the oven warms up, line a cupcake tin with festive cupcake liners to create a beautiful base for your Blackberry Swirl Cupcakes.
Step 2: Mix the Dry Ingredients
In a medium mixing bowl, whisk together 1 ½ cups of all-purpose flour, 2 teaspoons of baking powder, and a pinch of salt. This combination provides the essential structure needed for your cupcakes. Set the bowl aside as you prepare the wet ingredients, ensuring a light and fluffy texture.
Step 3: Cream Butter and Sugar
In a separate large bowl, cream together ½ cup of softened unsalted butter and 1 cup of granulated sugar using a hand mixer on medium speed until light and fluffy, about 3-4 minutes. This step is crucial for incorporating air into the batter, helping your Blackberry Swirl Cupcakes rise beautifully.
Step 4: Combine the Wet Ingredients
Add 2 large eggs, one at a time, mixing well after each addition. Then, stir in 1 teaspoon of vanilla extract until thoroughly combined. This will create a rich and flavorful base for your cupcake batter, elevating each bite with delicious notes of vanilla.
Step 5: Alternate Dry Ingredients and Milk
Gradually add the dry mixture to the wet ingredients while alternating with ½ cup of whole milk, starting and ending with the dry mixture. Mix just until combined, ensuring you don’t overmix. The batter should be smooth and silky, indicating it’s ready for the next step.
Step 6: Create the Blackberry Swirl
Gently fold in ½ cup of blackberry purée into the batter, doing so with a spatula to create a marbled effect. Be careful not to overmix; you want to see distinct swirls of blackberry throughout your batter for stunning Blackberry Swirl Cupcakes.
Step 7: Bake the Cupcakes
Spoon the batter into the prepared cupcake liners, filling each about two-thirds full. Place the tin in your preheated oven and bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean. The cupcakes should be lightly golden and spring back when touched.
Step 8: Cool the Cupcakes
Once baked, remove the tin from the oven and let the cupcakes cool in the tin for 5 minutes. Then, transfer them to a wire rack to cool completely. This step is critical before frosting, ensuring the Blackberry Swirl Cupcakes remain fluffy and delightful.
Step 9: Prepare the Frosting
In a clean mixing bowl, beat together ½ cup of softened butter and 2 cups of powdered sugar until creamy. Gradually add in 1 teaspoon of vanilla extract and enough heavy cream or milk (about 2-4 tablespoons) to achieve a smooth, spreadable consistency. This creamy frosting is the perfect compliment to your cupcakes.
Step 10: Add the Swirl and Garnish
Swirl in a couple of tablespoons of blackberry purée into the frosting for a beautiful color contrast. Once your cupcakes are completely cool, generously frost each one and garnish with fresh blackberries and optional mint leaves to enhance their visual appeal. Your Blackberry Swirl Cupcakes are now ready to impress!
