Lemon Cupcakes with Lemon Buttercream Frosting

Hello, Favorite Cake Flavor.

If you’ve been hanging around this blog the last 12 years, you know lemon and I have a thing. I love it wholeheartedly. So much so that when I’m asked “chocolate or vanilla” – I say lemon. There’s even a lemon dessert section on SS.

Earlier today I shared my lemon cake mix recipe and in this post I’ll show you how to turn the mix into the most incredible (you guessed it) cake! They flavor is perfection, the crumb texture is tender and the cake as a whole is that m-word that we only associate with cake. I topped these gems off with a giant dollop of homemade lemon buttercream.
