Smash Cake for a First Birthday

Smash Cake Recipe | Barbara Bakes

A little four inch chocolate birthday cake perfect for a first birthday celebration. 

For my grandson’s first birthday, my daughter wanted him to have his own little smash cake. I wanted him to have a homemade cake from grandma, so we bought a 4″ round cake pan at Gygi.

I combined the Old Fashioned Chocolate Cake recipe I posted last year with the Two Chocolate Cupcake recipe on Manhatton Craft Room to make just enough batter for one little 4 inch chocolate cake.

My grandson had never had cake before, but he couldn’t wait to get his little hands on his little birthday cake. My daughter had to put a little piece of cake in his mouth before he realized it was something to eat. It was so fun to see his eyes light up with that first taste of cake.

We were having 30 people at the party, so we needed a special cake for the adults too. I baked two chocolate cheesecake cakes. I’ll post that recipe on Friday.

Happy Birthday buddy!
