Mini Yellow Sheet Cake with Chocolate Frosting

A classic but make it romantic. Mini yellow sheet cake with chocolate frosting is the way to my heart. No frills or fuss, just a classic done right.  

While Valentine’s Day brings out the drama and intrigue when it comes to cooking a romantic dinner and impressing a loved one, I personally just want pasta alla vodka and this cake. Simple and so satisfying. 

Boxed yellow cake mix reigned supreme in our household growing up and it always makes me feel nostalgic whenever I have it. This homemade version is just BETTER and much fresher. Packed with buttery vanilla flavors, this yellow cake has the most moist and delicate crumb. And name a better frosting flavor pair than chocolate & yellow cake? It is so luscious and deliciously fluffy! Of course the roses are optional & festive. Rainbow Sprinkles are always best.

This cake starts off by creaming butter and sugar until light and fluffy. About 2-3 minutes. You don’t wanna over mix it. It gets its color from the eggs and egg yolk, also making it super moist. 

How to make a mini yellow sheet cake with chocolate frosting

  1. Cream the butter and sugar in a stand mixer fitted with a paddle attachment. 
  2. Add in the eggs one at a time, along with the vanilla extract.
  3. Add in your dry mixture alternating with your buttermilk mixture. Be sure to scrape the sides of the bowl down. 
  4. Pour into an 8 inch brownie pan and bake at 350 for 25/30 minutes. Until the center is set. 
  5. Wait for the cake to completely cool before frosting. Top with sprinkles or dried rose petals (optional).

This chocolate frosting is so deliciously fluffy and light and very nostalgic, I won’t have it any other way. I like to bake this in a 8 inch brownie pan, making it the perfect size for 2.
