    This smash cake is a little four-inch chocolate birthday cake perfect for a first birthday celebration. It’s an easy-to-make Smash Cake that your little one is going to love.

    A Smash Cake for Baby's first birthday

    For my first 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. The perfect size for a smash cake.

    I combined the Old Fashioned Chocolate Cake recipe with a two cupcake recipe to make just enough batter for one little 4 inch chocolate cake.

    The cake domes as it bakes, if you want, you can leave the rounded top. Or, use a serrated knife to trim the top flat.

    You can decorate the cake as simply as you’d like. I’ve used sprinkles and easy-to-make white chocolate curls on smash cakes.

    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.

    I frosted the chocolate smash cake with a simple cream cheese frosting. You could use chocolate frosting or chocolate ganache if you prefer.

    Two years later, I also made a smash cake for my second grandson’s first birthday. They have such fun sprinkles available online now, so it’s easy to make a simple cake look fun and festive.

    Last year we were excited to welcome our first granddaughter to the family and of course for her first birthday, I had to make something adorable. I bought a sweet little unicorn candle to top the cake and some fun unicorn sprinkles to decorate the cake.

    The smash cake was a hit with my granddaughter and all the people at the party.

    My daughter throws a big party with family and friends for her babies’ first birthdays, so we needed special cakes for the adults too. I baked two chocolate cheesecake cakes. It’s a triple layer cake with a cheesecake layer in the middle. (I’ll update that post with new pictures of the adults’ unicorn cake soon.)

    If you’re looking for a fun way to celebrate your little one’s first birthday, this easy-to-make smash cake is perfect.

      Hi thank you for all these amazing recipes! I’ve got a question: is it possible to leave out the vinegar?

        Thanks Lynn! No I wouldn’t leave out the vinegar. It’s an acid that helps the baking soda work it’s magic. You can’t taste it. Is there a reason you want to leave it out?

      I have another question if you don’t mind (I’m a novice). If I bake two of these little cakes at the same time, do I need to adjust baking times?

        No – it shouldn’t take any more time.

      Hi! I know you wrote this post some time ago, but I am hoping you still receive notice of comments. Could I omit the cocoa powder from the recipe to make a vanilla cake? If so, should I add something else (like a tablespoon of another dry ingredient) as a substitute? This cake is adorable and I’d like to try it for my little one’s first birthday. Thank you in advance!

        Hi Kristin – yes that should work well. I would add an extra tablespoon of flour and double the vanilla. Happy Birthday to your little one!

      Thank you thank you thank you for posting this!! 🙂 When my son turned 1 two years ago, I had to wing it and it turned out AWFUL! (Good thing all he did was smash it and eat some of the whipped cream off of it). I have volunteered to help a friend this year with her little girl’s first birthday cake, and would love to make her a smash cake as well!

      Barbara, the little cake is so cute. How nice to get granma to make a cake for the birthday boy. I wish I had my mom here to share that wonderful experience of a first birthday party.
      My little Emma is turning 1 next week, we are also having a little party and of course I am making a smash cake for her. She had never had cake before, so I am also waiting to see what she does when she sees her cake.
