Blueberry Cupcakes

You've heard of breakfast for dinner, what about breakfast for dessert? If you like to start your day with something sweet like blueberry muffins or blueberry pancakes, you'll adore these blueberry cupcakes.

These cupcakes are tender; they’re moistened with a touch of sour cream and studded with blueberries that burst and become juicy in the oven. Before baking, they're sprinkled with a spiced brown sugar mixture. Once cooled, swooping swirls of luscious blueberry cream cheese frosting are piped over the top for a luscious finish.

Blueberry Cupcake Components

These blueberry cupcakes are made with simple ingredients that pack a punch. When made correctly, each individual component adds to the overall flavor. 

• Cake batter: These blueberry cupcakes are a bit sweeter and lighter than blueberry muffins, thanks to a few choice ingredients. Using cake flour for cupcake batter makes the cakes more delicate and crumbly than those made with all-purpose flour. The amount of sugar also changes the overall texture slightly, making the cupcakes moister. Lastly, sour cream, rather than milk or buttermilk, is used to moisten the batter and also adds a slight hint of tanginess to the cupcakes. 
• Sugar topping: This three-ingredient topping (made with granulated sugar, brown sugar, and cinnamon) acts similarly to the streusel filling inside a coffee cake. It adds a touch more sweetness as the sugar and spices melt into the cupcake batter as they bake. 
• Frosting: Cream cheese frosting is everyone's favorite—it's not overly sweet and it has the most perfect creamy texture. To bring home the blueberry flavor, some blueberry jam is swirled into the frosting before being piped onto the cupcakes. Not only does it create a striking design, but it also adds a pop of color and flavor.

5 Tips for Making Perfect Cupcakes

If you want cupcakes that come out moist and fluffy every time, consider the following:

1. Cream the butter and sugar properly: To make cupcakes that rise to lofty heights, you want to incorporate some air into the butter and sugar mixture. This is the first and most crucial step. While eggs and leavening agents like baking soda and baking powder will give the cupcakes some lift, it’s important to start off by creaming the butter and sugar well and thoroughly. Use the mixer’s paddle attachment to beat the mixture until it is light, fluffy, and almost doubled in volume. 
2. Slowly incorporate the eggs: By adding eggs to the batter one at a time, they will incorporate into the batter much more easily. Be sure to wait until each egg is fully mixed in before adding the next; also, stop a few times to scrape down the sides of the bowl. 
3. Use room-temperature ingredients: This is especially important for butter and eggs. The overall texture of the cupcakes will be much more even if you allow your ingredients to come to room temperature before mixing. 
4. Alternate adding wet and dry ingredients. We do this for the same reason we use room-temperature ingredients. Give the batter time to rehydrate before adding more flour and your cupcakes will bake up moist and even each time. 
5. Don't overmix. This is probably the number one mistake home cooks make when making baked goods like cakes and cupcakes, but also cookies and brownies. Stir the batter just until the flour is incorporated. Overmixing can make the cupcakes tough and dry.

Testing the Cupcakes Are Done

These blueberry cupcakes are quite moist, and since they’re chock-full of blueberries, testing for doneness can sometimes be deceiving. When inserting a toothpick into the cupcake, it will likely be covered in juices from the berries—you may have to poke it more than once to find a spot where you don’t encounter a blueberry. Once you find it, the toothpick should come out with some moist cake crumbs still attached.
