These lemon cupcakes with raspberry buttercream are the epitome of summer! Lemon and raspberry pair so ridiculously well together. The raspberry buttercream is absolutely DELICIOUS and goes so well with he lemon cupcake base. It’s made with fresh raspberries and it’s total spoon to the bowl delicious that I almost didn’t want to frost the cupcakes with it.
The lemon cupcake recipe is one I’ve been coming up with and testing over and over again for a while. They’re made with fresh lemon zest and juice, giving you a totally fresh and tangy-but-sweet-at-the-same-time cupcake! They are fluffy, yet dense and sturdy enough to stand up to a whole lot of frosting. To me, they’re perfect cupcake texture! I know you guys will love these.
Ingredients needed for Lemon Cupcakes
For the cupcakes
- All-purpose flour: Flour of choice for these cupcakes
- Granulated sugar: To sweeten the cupcakes
- Baking powder: This makes the cupcakes rise during baking.
- Unsalted butter: Creates a rich texture and also lends amazing flavor.
- Egg whites: To keep the cupcakes light and airy.
- Vanilla extract: For flavor.
- Sour cream: To keep the cupcakes moist.
- Milk: I like to use whole milk in this recipe but you can also use 2% if that is what you have on hand.
- Lemon zest: FLAVOR
- Lemon juice: More flavaaaa
- Butter: Unsalted to control sodium.
- Powdered sugar: To sweeten and thicken frosting.
- Salt: I use a small amount to balance the sweetness.
- Raspberry sauce: Made from fresh raspberries, granulated sugar and lemon juice.
How to make the cupcakes
- Make batter: Whisk flour and baking powder together and set aside. In a large bowl, cream butter and sugar together until smooth. Add egg whites and vanilla and beat until light and fluffy. Add milk, sour cream, lemon juice and lemon zest stirring until completely combined. Pour in flour mixture and mix until just incorporated.
- Fill: Distribute batter to cupcake liners and fill them 2/3 full.
- Bake: Bake for 18-20 minutes or until a toothpick inserted in the center comes out clean.
How to make Raspberry Buttercream Frosting
- Make raspberry sauce: Add raspberries to a small saucepan and toss them with sugar and lemon juice.
- Simmer: Simmer on low heat for 8-10 minutes, stirring occasionally and watching closely making sure they do not thicken up too much. Mash them in the pot very well and then transfer to a fine mesh sieve or strainer over a bowl and strain them to get all of the juice out. Cool to room temperature. Tip: Transfer to the refrigerator and stir often.
- For the frosting: Cream butter until smooth. Add salt and powdered sugar one cup at a time. Pour in cooled raspberry sauce slowly until desired thickness is achieved.
- Frost: Pipe the frosting on the cooled cupcakes.
