These moist lemon blueberry cupcakes are always a showstopper at my family gatherings and make perfect spring or summer treats when fresh berries are sweetest. With just a few extra additions to boxed cake mix, these cupcakes come out ultra light with a bold lemony punch and pops of juicy blueberry in every bite. A luscious lemon cream cheese frosting puts them over the top for birthdays, baby showers or a simple weekend joy.
I first baked these for a late May picnic and my sister said they tasted like sunshine and reminded her of summer as a kid. Now she requests this exact recipe every Mother’s Day.
Ingredients
- White cake mix: Using a reliable mix means a consistent base and saves time. Sift first for a fluffier cupcake
- All purpose flour: Gives extra structure and lift to support the blueberries
- Sugar: For balanced sweetness and added tenderness
- Instant lemon pudding: This is key for a super moist crumb and strong lemon flavor. Use name brand for best results
- Large eggs: Binds everything together and adds richness. Choose fresh eggs for best volume
- Water: Ensures the batter stays just the right consistency
- Sour cream: Adds richness moisture and tang. Full fat makes a difference
- Lemon extract: Intensifies citrus flavor throughout the cake
- Vanilla extract: Rounds out the lemon so it is not too sharp. Go for pure vanilla if possible
- Lemon zest: This adds big lemon fragrance and tiny bits of citrus flavor throughout
- Blueberries: Juicy pops of flavor and color in every cupcake. Fresh berries hold up best but frozen ones work in a pinch. Look for plump berries with no shriveling
For Lemon Cream Cheese Frosting
- Unsalted butter: Softened for extra creamy frosting. Use best quality available
- Full fat cream cheese: Gives thick tangy frosting that pipes beautifully
- Lemon juice: Brings more lemon brightness
- Lemon extract: Ups the citrus punch
- Lemon zest: Natural oil-rich flavor and fragrance
- Powdered sugar: for structure and sweet flavor. Sift for super smooth texture
Step-by-Step Instructions
- Prepare Cupcake Pan:
- Line cupcake pans with paper liners and set aside
- Mix Dry Ingredients:
- Into a large mixing bowl add cake mix all purpose flour sugar and lemon pudding powder. Whisk together for about thirty seconds so everything is well blended and no lumps remain
- Make the Batter:
- Add eggs water sour cream lemon extract vanilla extract and lemon zest to the dry bowl. Use a stand or hand mixer to blend on medium for one minute. Scrape down the sides then mix a full minute again. This brings everything together into a thick and creamy batter
- Add Blueberries:
- Scoop the batter into cupcake liners filling each about two thirds full. Top each with four to five blueberries gently pressing them just into the surface. Some berries will stay on top as they bake and others will sink a bit for a pretty mix
- Bake Cupcakes:
- Slide pans into the oven and bake at three hundred fifty degrees for sixteen minutes. Cuppies are ready when the centers bounce back with a gentle touch or a toothpick comes out with just a crumb or two
- Cool the Cupcakes:
- Remove pans and carefully turn cupcakes onto a cooling rack after a minute or two so they do not overbake in the pan. Let them cool fully before frosting
- Prepare Lemon Cream Cheese Frosting:
- Start by mixing softened butter until smooth then add room-temp cream cheese in chunks. Cream together until no lumps remain. Sprinkle in lemon juice zest and lemon extract then mix just to combine. Add sifted powdered sugar slowly blending until smooth fluffy and thick enough to hold a swirl
- Decorate:
- Once cupcakes are completely cool spread or pipe frosting onto each one. Pipe a tall swirl using a 1M tip if you like bakery style. Add a fresh blueberry on top for a simple finish

Every time I zest a lemon for these I remember my daughter chasing the scent around the kitchen and asking for “just one berry please.” It has become a tradition for her to help place blueberries on top right before baking and she loves to see how some berries peek out after they rise.
Storage Tips
Because of cream cheese frosting these cupcakes need to be refrigerated. Place them in a single layer in an airtight container so the frosting stays fluffy and the cakes do not dry out. Let them come to room temperature for an hour or two before eating so the flavors soften and the texture returns to tender and moist.
Ingredient Substitutions
If you do not have instant lemon pudding try using instant vanilla pudding plus a little extra lemon zest and lemon juice. Greek yogurt can work in place of sour cream for a tangy twist. Frozen blueberries are a fine replacement for fresh but toss them in a tiny bit of flour first to prevent major streaks. If you only have salted butter reduce the added salt elsewhere in the frosting.
Serving Suggestions
These cupcakes steal the show at spring teas Mother’s Day brunches and graduation parties. For a bright dessert platter try garnishing with lemon curls extra blueberries or a dusting of edible glitter for extra fun. Serve them alongside fresh berry salad for a lighter finish.

Cultural and Historical Context
Lemon and blueberry is a classic pairing in American baking dating back to regional cakes and quick breads especially popular in the Northeast where wild blueberries thrive. This recipe gives that old-fashioned homemade flavor but is simple enough for busy modern bakers to whip up without fuss.
