Lemon Blueberry Cupcakes with Lemon Cream Cheese Frosting

Jump to Recipe

Based on my beloved lemon blueberry cake recipe, this cupcake version features super soft yet moist lemon cupcakes with fresh blueberries perfectly suspended inside and irresistible lemon cream cheese frosting. The flavor is created with every part of the lemon – no lemon extract required! Instead, using lemon zest and juice yields the perfect bright, sunny lemon flavor in the cupcakes and the frosting. And they’re somehow even MORE moist and fluffy the next day – the perfect make-ahead dessert for a brunch, Easter, an upcoming birthday, or any celebratory event! 

Lemon Cupcakes with Perfectly Suspended Blueberries

As with my lemon cake, it was super important to me to ensure that the blueberries won’t sink to the bottom of these cupcakes. The size of blueberries can vary greatly, and the larger they are the heavier they are. In other words, blueberries that are too big are more likely to sink in the baking process. To prevent that entirely, there are two things I do:

1. Cut the blueberries in half. Using a paring knife, I cut the blueberries in half to decrease their size. I was nervous to do this at first because I didn’t want the blueberries leaking in the baking process, but to my surprise they didn’t leak at all! Reducing their size ensures they stay put when baked. 
2. Coat the blueberries in flour. This may be one of the reasons why the cut blueberries didn’t leak, and is also a known technique that adds a layer of protection from sinking. 

Lemon Blueberry Cupcake Ingredients

This lemon blueberry cupcake recipe uses every part of a lemon to get the perfect citrus flavor. The zest is mixed together with the sugar to release essential oils + the juice is added to the milk to create buttermilk, which adds both flavor and moisture. In fact, these cupcakes are known to stay moist and fluffy for days. Here are the key ingredients that make them special:

• Lemon zest + fresh squeezed lemon juice. As mentioned previously, this recipe uses every part of the lemon for flavoring this cake. The lemon zest is mixed with the sugar in the beginning of the recipe to release lemon essential oils from the beginning. Then, you’ll juice the lemon into the milk to create a homemade buttermilk that adds lots of moisture and flavor at the end of the recipe. In total, you’ll need about 2 medium lemons.  
• All-purpose flour. Although I love using cake flour for a super soft crumb in lots of my recipes, all-purpose flour (or plain flour) is the best choice here. It has the right structure to make the batter thick enough for suspending those blueberries, yet somehow yields a tender and fluffy cupcake. 
• Whole Milk. In the beginning of the recipe, you’ll add lemon juice to the whole milk to create homemade buttermilk. This creates moisture and adds flavor to the cupcakes. Since whole milk has a high amount of fat and protein, it’s the best choice for adding moisture while binding the ingredients together. The best substitutes here would be soy milk or full-fat buttermilk, but whole milk is my recommendation. 
• Granulated Sugar. This not only sweetens the cupcakes but also tenderizes the crumb, making it softer.
• Butter + Vegetable Oil. These are the two base fats I use in this recipe – a little bit of butter for a rich texture and a little bit of vegetable oil for added moisture. 
• Large Eggs. These add structure to the cupcakes and help bind the ingredients together. 
• Fresh Blueberries. I don’t recommend any substitutes here. Frozen blueberries have extra water content that will throw off the structure, and freeze-dried blueberries don’t have enough water content so they’ll end up the texture of raisins. Fresh blueberries are best!

Irresistible Lemon Cream Cheese Frosting

Just like the layer cake version, these cupcakes are frosted with a lemon cream cheese buttercream that is so light and delicious. To make the lemon cream cheese frosting extra stable without having to add extra powdered sugar or stabilizers, we’ll use a slightly different order of mixing the ingredients than a standard cream cheese frosting recipe. Instead of creaming the butter and cream cheese together in the beginning of the recipe, the cream cheese gets added last. This makes it the perfect consistency for piping onto cupcakes! 

As with any cream cheese frosting, there are a couple best practices you need to know to ensure success:

• Use full-fat brick-style cream cheese. It’s critical that you don’t use low-fat or spreadable cream cheese, as these variations contain way more water than the full-fat brick kind. That means your frosting will be extra soft, liquidy, and impossible to decorate with. I always use the Philadelphia brand, but feel free to experiment with other brands as long as they meet the general requirements. 
• Use refrigeration. If you find that your kitchen environment is humid or the frosting is still a bit soft, pop it in the refrigerator for 10-15 minutes, then re-mix it on low in your stand mixer. The butter in the recipe will solidify a little bit in the refrigerator, so the overall buttercream will feel a bit thicker and easier to work with afterwards.

Other Frosting Suggestions for Lemon Blueberry Cupcakes

If you live in an area without access to full-fat brick-style cream cheese or you simply don’t want to make that extra trip to the store, I have a few other suggestions for frosting these lemon blueberry cupcakes: 

• Lemon Buttercream
• Vanilla Buttercream
• Blueberry Buttercream
• Lavender Buttercream
• White Chocolate Buttercream
