Spring has arrived! And along with it… all things lemon. There’s just something about lemon that feels so perfect for spring. It’s bright and fresh and feels like sunshine, and it’s one of my absolute favorites for spring baking.

From Lemon Zucchini Bread to Lemon Raspberry Coffee Cake, there’s no denying that fresh lemon completely transforms any recipe. Including these lemon cupcakes! They’re chock full of fresh lemon juice and lemon zest and topped with a sweet, tart lemon buttercream frosting.

I don’t know about you, but I like my cupcakes a little bit dense, and these cupcakes are exactly that. They’re the perfect balance of sweet and lemony and cakey and chewy. And loaded with lemon flavor. In other words, they’re absolutely perfect.

And when you top them with JUST the right amount of buttercream? They’re out of this world delicious.

what you’ll need for this recipe

Dry ingredients – These make up the base of the cupcakes and are traditional ingredients found in many baked goods: all purpose flour, baking powder, and salt. I also added poppy seeds to this recipe for a fun twist! (Feel free to omit them if you prefer.)

Wet ingredients – These ingredients make the cupcakes moist and give them their delicious flavor! I used a combination of butter, sugar, lemon juice, lemon zest, eggs and milk.

Buttercream – The BEST homemade Lemon Buttercream Frosting, made with butter, powdered sugar, lemon juice, and milk. I also topped the cupcakes with lemon zest and a few extra poppy seeds.

Pro Tips

Measure your ingredients accurately. Most importantly? Be sure you spoon your flour into the measuring cups instead of scooping. This ensures that your cupcakes won’t end up dry.

If possible, use fresh lemon juice. As with any fresh ingredients, fresh lemon juice will give you the most authentic (and delicious) lemon flavor!

Use a cookie scoop to measure batter. I love using a cookie scoop to guarantee that all my cupcakes turn out the same size.

Double the frosting recipe. If you’re anything like me, the frosting is the best part. Don’t be afraid to double it up!

  1. This flavor combination is perfect especially for a baby shower! I’ll make sure to eat at least two in honor of the twins.

  2. 5 stars
    Wow! This can be one particular of the most useful blogs We’love ever arrive across on this subject. Actually Excellent. I am also a specialist in this topic therefore I can understand your effort.

  3. So what do I do with the other half of the dry ingredients. Doesn’t say what to do with the other half unless I missed a step?

      1. What did you do? I”m going to see how wet this looks and likely add all the dry, surprised the proof read/ tester didn’t catch this big mistake.

  4. FYI your recipe says 9 cups of powdered sugar !! Haha that really stressed me out until I got to the steps later on and realized it’s only 2.
    Freakin delicious cupcakes and I’ve only tasted the batter!

  5. I love this recipe! But I personally like a tangy and more sour flavor. So instead of 5 tablespoons of lemon juice I put way more and used 1/2 cup. I also put more lemon juice in the frosting! I would also recommend putting a lot more zest in as well:)
