👩‍🍳 Step-by-Step Instructions (with Time Breakdown)

⏱ Total Time: 45 minutes

• Prep: 15 min

• Bake: 18–20 min

• Cool & Frost: 10–15 min

Step 1: Preheat & Prep

Preheat oven to 350°F (175°C). Line your muffin tin with cupcake liners.

Step 2: Mix Dry Ingredients

In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.

Step 3: Cream Butter & Sugar

In a large bowl, beat butter and sugar until light and fluffy (about 2–3 minutes). Add eggs one at a time, mixing well after each.

Step 4: Add Flavor

Mix in vanilla, lemon zest, and lemon juice. Scrape down the sides to ensure even mixing.

Step 5: Combine Wet & Dry

Alternate adding dry ingredients with sour cream and buttermilk. Start and end with dry. Mix until just combined—don’t overmix!

Step 6: Fold in Blueberries

Gently fold in blueberries with a spatula. Use an ice cream scoop to divide batter evenly into liners.

Step 7: Bake

Bake for 18–20 minutes or until a toothpick comes out clean. Let cool in the pan for 5 minutes, then transfer to a wire rack.

Step 8: Make the Frosting

Beat butter until creamy. Gradually add powdered sugar, lemon juice, zest, and salt. Beat until fluffy (about 3–4 minutes). Add food coloring if desired.

Step 9: Frost & Serve

Once cupcakes are completely cool, frost using a piping bag or spatula. Garnish with extra zest or a fresh blueberry on top.

🎯 Expert Baking Tips

• Room temp ingredients: Ensure butter, eggs, and dairy are at room temperature for a smooth batter.

• Toss blueberries in flour: This prevents them from sinking to the bottom.

• Don’t overmix: Overworking the batter can lead to dense cupcakes.

• Use fresh lemons: Bottled juice lacks the brightness of fresh citrus.

🌈 Creative Variations

1. Lemon Raspberry Cupcakes

Swap blueberries for fresh raspberries and add a touch of almond extract to the batter.

2. Blueberry Cream Cheese Frosting

Replace lemon buttercream with a tangy cream cheese frosting and swirl in blueberry jam.

3. Lemon Poppy Seed Cupcakes

Add 1 tbsp poppy seeds to the batter for a bakery-style twist.

✨ What Makes These Cupcakes Unique?

Unlike standard lemon cupcakes, this recipe uses both sour cream and buttermilk for a super tender crumb. The double dose of lemon (zest + juice) ensures a bright flavor that doesn’t get lost in the bake. And the fresh blueberries? They burst like little flavor bombs in every bite.

🧊 Storage & Serving Suggestions

• Storage: Keep cupcakes in an airtight container at room temp for 2 days or refrigerate for up to 5 days.

• Freezing: Unfrosted cupcakes freeze beautifully. Wrap individually and freeze for up to 2 months.

• Serving: Serve slightly chilled or at room temp. Pair with iced tea, lemonade, or a sparkling rosé for a summery vibe.
