Ingredients
Method
Make the Blueberry Topping
- Combine the blueberries, sugar, and lime juice in a small saucepan over medium heat. Stir gently.
- Cook until the blueberries soften and release their juices, approximately 4 to 5 minutes.
- Mix cornstarch and cold water in a small cup until smooth, then add to the saucepan, stirring constantly until thickened.
- Remove from heat, transfer to a bowl, cover with plastic wrap, and let cool.
Prepare the Cheesecake Filling
- Beat softened cream cheese until smooth, about 1 minute.
- Add sugar, egg, lime juice, and vanilla extract; mix until just combined.
- Transfer to a piping bag and refrigerate.
Make the Lime Cupcake Batter
- Preheat oven to 350°F (175°C) and line a muffin tin with paper liners.
- Whisk together the flour, baking powder, baking soda, and salt in a medium bowl.
- Beat butter and sugar together for about 3 minutes until pale and fluffy.
- Add eggs one at a time, mixing well after each, then add vanilla, lime juice, and zest.
- Gradually incorporate dry ingredients alternating with milk, mixing until just combined.
Fill and Bake the Cupcakes
- Fill each muffin cup with about 2 tablespoons of batter, then add 1 heaping tablespoon of cheesecake filling.
- Cover with another tablespoon of batter, then bake for 20 to 22 minutes.
- Cool in pan for 5 minutes, then transfer to a wire rack to cool completely.
Make the Lime Cream Cheese Frosting
- Beat cream cheese and butter together until smooth, about 2 minutes.
- Gradually add powdered sugar and beat on low to avoid a sugar cloud.
- Finally, add lime juice, zest, and salt, beating until fluffy.
Frost, Top, and Serve
- Frost each cooled cupcake generously and add blueberry topping on top.
- Optional: garnish with lime zest or a lime wheel.
- Refrigerate for at least 30 minutes before serving.
Notes
Use full-fat cream cheese for best texture. Make sure all ingredients are at room temperature for optimal blending. Chill cupcakes for better flavor integration.
