Directions

Make the Cupcakes

1. I preheat the oven to 350°F (175°C) and line a 12-cup muffin tin with cupcake liners.
2. In a medium bowl, I whisk together the flour, baking powder, and salt.
3. I toss the blueberries with 1 tablespoon of flour to help prevent them from sinking.
4. In a large bowl, I beat the butter and sugar until light and fluffy, about 2–3 minutes.
5. I add the eggs one at a time, mixing well after each addition.
6. I mix in the vanilla extract, lime juice, and lime zest.
7. I add the dry ingredients in three additions, alternating with the milk, beginning and ending with the flour mixture.
8. I gently fold in the blueberries.
9. I fill the cupcake liners about two-thirds full.
10. I bake for 18–22 minutes, or until a toothpick inserted into the center comes out clean.
11. I allow the cupcakes to cool completely before frosting.

Make the Lime Buttercream

1. I beat the butter until smooth and creamy.
2. I gradually add the powdered sugar while mixing on low speed.
3. I add the lime juice, lime zest, salt, and cream.
4. I beat the frosting for 2–3 minutes until it becomes light and fluffy.
5. I pipe or spread the frosting onto the cooled cupcakes.

Decorate

1. I top each cupcake with fresh blueberries.
2. I sprinkle extra lime zest over the frosting.

Variations

• I use frozen blueberries when fresh berries are unavailable, adding them directly without thawing.
• I add an extra teaspoon of lime zest for a stronger citrus flavor.
• I replace the lime with lemon for a blueberry lemon cupcake variation.
• I fill the cupcakes with blueberry jam for an extra fruity center.
• I add a touch of coconut extract to the frosting for a tropical twist.
• I garnish with candied lime slices for a more elegant presentation.

storage/reheating

I store these cupcakes in an airtight container at room temperature for up to 3 days. If I need to keep them longer, I refrigerate them for up to 5 days.

Before serving refrigerated cupcakes, I let them sit at room temperature for about 20–30 minutes so the frosting can soften and the flavors can fully develop.

For longer storage, I freeze the unfrosted cupcakes in a freezer-safe container for up to 3 months. I thaw them overnight in the refrigerator and frost them before serving.

FAQs

Can I use frozen blueberries instead of fresh?

Yes, I can use frozen blueberries without thawing them first. This helps prevent excess moisture from affecting the batter.

Why do I coat the blueberries with flour?

I coat the blueberries with flour because it helps keep them suspended throughout the batter rather than sinking to the bottom during baking.

Can I make the cupcakes ahead of time?

Yes, I often bake the cupcakes a day ahead and store them covered until I am ready to frost and serve them.

How can I make the lime flavor stronger?

I add extra lime zest to both the batter and frosting when I want a more pronounced citrus flavor.

Can I use bottled lime juice?

I prefer fresh lime juice because it provides the brightest flavor, but bottled lime juice can be used if necessary.

The tender cupcakes, juicy blueberries, and creamy lime buttercream create a dessert that feels light, vibrant, and perfect for any occasion. Whether I am baking for a party, family gathering, or simply treating myself, these cupcakes always deliver beautiful flavor and irresistible presentation.
