Lemon Blueberry Cupcakes are a bright, cheerful treat that combines the tangy zing of fresh lemon with bursts of juicy blueberries. These cupcakes are soft and fluffy, with sweet blueberries scattered throughout the batter and a light lemon frosting on top that adds just the right amount of citrusy freshness. They’re a perfect balance of sweet and tart, making every bite feel like a little party of flavors.
I love making these cupcakes when I want something that feels special but isn’t too fussy. The blueberries stay plump and juicy after baking, which is such a nice surprise in every mouthful. I usually use fresh lemons for the zest and juice to give them a bright flavor that lifts the whole cupcake, and I find that a little lemon zest on the frosting adds a lovely touch to finish them off.
These cupcakes are wonderful for sharing at spring or summer gatherings, but honestly, they’re just as great as a simple afternoon treat with a cup of tea or coffee. I’ve noticed everyone tends to love them at parties because they’re light, colorful, and not too sweet — they feel like a fresh twist on a classic cupcake. Plus, they’re fun to make, and I always enjoy sneaking a blueberry or two while baking!
Key Ingredients & Substitutions
Flour: All-purpose flour is perfect for light, tender cupcakes. If needed, you can try a 1-to-1 gluten-free blend, but the texture might be a bit different.
Butter: Unsalted butter adds richness and controls salt levels. You can use salted butter but reduce added salt slightly. Room temperature butter creams best for fluffier cupcakes and frosting.
Blueberries: Fresh blueberries are best to keep their shape in the batter. Frozen can be used, but toss them in a bit of flour first to avoid sinking or color bleeding.
Lemon: Fresh lemon zest and juice deliver bright citrus flavor. Bottled lemon juice won’t be as vibrant, so fresh is worth the effort here.
Milk: Whole milk adds moisture and richness. You can swap for buttermilk or a plant-based milk for a different twist or to suit dietary needs.
Sugar: Granulated sugar makes the cupcakes sweet and tender. For frosting, powdered sugar creates a smooth texture but check for cornstarch if you have allergies.
How Do I Keep Blueberries Intact and Prevent Sinking in Cupcakes?
Blueberries can be tricky—they tend to burst or sink during baking. Here’s how to keep them whole and well distributed:
- Gently fold: Add blueberries last and fold carefully into the batter to avoid breaking them.
- Coat with flour: Toss blueberries with a teaspoon of flour before mixing in to help them stay suspended.
- Even batter: Don’t overmix; a thicker batter supports fruit better.
- Fill cups properly: Fill cupcake liners about 2/3 full for enough room to bake without blue juices spilling over.
Following these steps will give you beautiful cupcakes with bright, plump blueberries in every bite.
Equipment You’ll Need
- Standard muffin tin and cupcake liners – These make baking clean and easy, giving your cupcakes a perfect shape.
- Medium mixing bowls – You’ll need one for dry ingredients and one for wet, keeping things organized.
- Hand or stand mixer – Makes beating butter and sugar quick and fluffy, saving time and effort.
- Rubber spatula – Great for gently folding in blueberries without breaking them.
- Cooling rack – Helps cupcakes cool evenly, preventing sogginess and making frosting easier.
- Piping bag or spatula – For decorating with frosting neatly and smoothly.
Flavor Variations & Add-Ins
- Swap blueberries for raspberries or strawberries for a different berry flavor or use a mix for color and taste variety.
- Add a teaspoon of poppy seeds to the batter for a subtle crunch and a pretty look.
- Mix in chopped nuts like almonds or walnuts for extra texture and flavor.
- Use cream cheese in the frosting for a tangy, richer finish, especially good with citrus flavors.

- 1/4 tsp salt
- 1/2 cup unsalted butter, room temperature
- 1 cup granulated sugar
- 2 large eggs
- 2 tsp vanilla extract
- 1/2 cup whole milk

- 2 tbsp fresh lemon juice
- 1 cup fresh blueberries (plus extra for topping)
For the Frosting:
- 1 cup unsalted butter, room temperature

- 2-3 tbsp fresh lemon juice
- 1 tsp lemon zest
- 2-3 tbsp heavy cream or milk (to adjust consistency)
- 1 tsp vanilla extract
For Garnish:
- Fresh blueberries
- Thin lemon slices or lemon wedges
How Much Time Will You Need?
This recipe takes about 15 minutes of preparation and around 18-22 minutes for baking. Allow additional time to cool the cupcakes completely before frosting, about 20-30 minutes. Altogether, plan for roughly 50-60 minutes to enjoy your fresh, homemade Lemon Blueberry Cupcakes.
Step-by-Step Instructions:
1. Get Ready:
Preheat your oven to 350°F (175°C). Line a muffin tin with cupcake liners so the batter doesn’t stick and cleanup is easier.
2. Mix Dry Ingredients:
In a medium bowl, whisk together the flour, baking powder, and salt. Set this dry mix aside for now.
3. Cream Butter and Sugar:
In a large mixing bowl, beat the softened butter and granulated sugar together using a hand or stand mixer. Keep going until the mixture looks light and fluffy, about 3 to 4 minutes.
4. Add Eggs and Flavors:
Beat in the eggs one at a time, mixing well after each. Then, stir in the vanilla extract, lemon zest, and fresh lemon juice for that bright citrus flavor.
5. Combine Wet and Dry Ingredients:
Add the flour mixture into the wet ingredients gradually, in three parts. Alternate with adding milk in two parts. Start and end with the flour mix. Carefully mix until all ingredients are just combined; avoid overmixing to keep cupcakes tender.
6. Fold in Blueberries:
Gently fold fresh blueberries into the batter with a spatula. This helps keep the berries intact instead of breaking them up.
7. Fill Cupcake Liners:
Divide the batter evenly among the cupcake liners, filling each about two-thirds full. This gives room for the cupcakes to rise nicely.
8. Bake:
Bake in the preheated oven for 18 to 22 minutes. To check doneness, insert a toothpick in the center — it should come out clean.
9. Cool the Cupcakes:
Remove the cupcakes from the oven, let them cool in the tin for 5 minutes, then transfer to a wire rack. Allow them to cool completely before frosting.
10. Make the Frosting:
Beat the butter in a clean bowl until creamy. Gradually mix in the powdered sugar, beating well after each addition. Then add lemon juice, lemon zest, vanilla extract, and 2 tablespoons of cream or milk. Beat on high until light and fluffy. Add more cream or sugar until you get a smooth, spreadable consistency.
11. Frost and Garnish:
Once the cupcakes are fully cooled, spread or pipe the lemon frosting on top. Garnish each cupcake with fresh blueberries and a thin slice or wedge of lemon for a lovely finishing touch.
12. Enjoy!
Your refreshing Lemon Blueberry Cupcakes are ready to enjoy. Perfect for a sunny day or any occasion that calls for a sweet, citrusy treat!
Can I Use Frozen Blueberries Instead of Fresh?
Yes, you can! Just thaw them completely and toss them in a little flour before folding into the batter to prevent sinking and color bleeding.
How Should I Store Leftover Cupcakes?
Store cupcakes in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate for up to 5 days, but bring to room temperature before serving for the best flavor.
Can I Make the Frosting Ahead of Time?
Absolutely! Prepare the frosting and keep it covered in the fridge for up to 3 days. When ready to use, let it soften at room temperature and re-whip if needed to regain its fluffy texture.
What Can I Substitute for Heavy Cream in the Frosting?
You can use whole milk or a plant-based milk like almond or oat milk. Add it gradually to get the right consistency without thinning the frosting too much.
