Perfect Lemon Rainbow Cupcakes (and Rainbow Birthday Party Theme)

Sharing is caring!

Since April showers bring May flowers…hopefully…I figured I would share these Perfect Lemon Rainbow Cupcakes I made for Sofie’s 1st birthday party/ St. Patty’s Day! I finally perfected my lemon cupcake recipe and am super excited, they were so moist with just the right amount of lemon! These would be cute for a Spring gathering or fun for a kids Rainbow themed birthday party!

Why I love these Perfect Lemon Rainbow Cupcakes

I was excited to MASTER my lemon cake recipe. So if you are looking for rainbow cupcake ideas, I hope you find this recipe helpful (and easy). They are moist, just the right amount of lemon, and fun! Made from scratch and are great for the lemon dessert lovers in your life.

Rainbow Birthday Party Theme Ideas

Since we had her party on St. Paddy’s Day I wanted a theme to go with that so I figured rainbows (pots of gold at the end…) you get the idea! We had rainbow colored Twizzlers, rainbow colored Goldfish, and rainbow suckers! I also made my Leprechaun Magic Crack as a fun treat for the kids.

I attempted to be cute with a rainbow fruit & veggie tray combined….

Rainbow Party Decorations

I hung all of Sofie’s month pictures over her on the rainbow colored flags (dollar store) with clouds at the end that we had at the baby shower! Anyways it was cute and the cupcakes were a success!

I got the rainbow colored plates, flags, and banner at the Dollar store. I am sure they have them at Party City, too.

Rainbow Themed Cupcakes and Mini Cake

I wanted Sofie to have her own personal cake since she would be “smashing” it. So I separated some of the batter and made her her own mini cake. I wrapped the cake in the rainbow belts candy.

So here is the recipe for my Lemon Cupcakes with the perfect Cream Cheese Frosting! This recipe makes about 30 cupcakes so if you have a smaller group just cut it in half! For help decorating, check out my Decorating Tips post!
