A Smash Cake that’s Delicious and Healthy

A Smash Cake that’s Delicious and Healthy

I’m not a food blogger, but I feel the need to share this smash cake recipe with you.

When my daughter was nearing her first birthday, I wanted her to have the experience of shoving her face full of cake. But, I wasn’t too keen on filling her up with processed sugar and all the typical cake ingredients. So, I combined some old recipes and picked out ingredients that I was okay with feeding my baby. The result was this delicious and healthier version of a cake! It turned out great, and my daughter looooooved it. If you are like me, this recipe will put your mind at ease. I was able to enjoy watching my kiddo eat her birthday cake without cringing at every bite.

Just to make sure it wasn’t a lucky experience, I made the cake a second time for a friend’s son. Turns out it was a hit for him, too. I felt like two children was a big enough sample size to justify sharing it with the world.

The Process:

Mix and Bake the Cake!

To make this cake, mix the batter and then divide it into two 6″ cake pans.

Don’t have two 6″ cake pans? Let’s problem solve. If you own one 6″ cake pan, then you can bake each cake separately using the same pan. Or, maybe you are like me and don’t own any cake pans. Before running to the store to buy one, look through your cupboards to see if you have a possible substitute. Do you have any other bakeware that is 6ish inches in diameter? Really, anything between 4-8″ diameter would work, even if it’s square. I found this baking bowl (for lack of a better term) in the back of my cupboard, and it worked great.

Make the Frosting

Once you’ve baked two same-sized cakes, set them aside and let them cool. Now you can make the frosting (usually best if made day-of, but it’s okay to make it a day in advance if it makes your life easier). Whip the heavy whipping cream with an electric mixer for about 10 minutes (or until it reaches the consistency you want). I suppose you could do it by hand, but I imagine you will get extremely pumped. Careful not to over-mix, in which case you can actually turn the whipping cream into butter.

Whip the heavy whipping cream with an electric mixer for about 10 minutes, or until your frosting reaches the desired consistency.

Smash or blend the blueberries into a puree and fold them into the frosting. Then your frosting is done!

Smash Cake Assembly!

Now for the fun part – building the cake.

Start by placing one of your two cakes on the plate that you plan to serve to your baby. Moving the cake to another surface after it’s assembled is doable, but not easy. Choose a non-breakable serving plate (preferably not a paper plate, as this did not hold up well for us).

Next, add a layer of frosting to the cake.

Step 1: Place one of the cakes on the plate you plan to serve to your baby.
Step 2: Add a layer of frosting to the top of this cake.

Place your second cake on top of the frosted first cake. You can place this cake layer right-side-up or upside-down. I’ve done it both ways, and both worked well. Right-side-up makes for a slightly more rounded cake top, as well as less frosting in-between cake layers. Upside down (as pictured here) lends to a more flat-topped cake and more frosting between layers. Regardless of which way you place the second cake, fill in the gaps between both cake layers with frosting. I used a silicone spatula, which made it super easy.

Step 3: Place second layer of cake on top.
Step 4: Fill in gaps between cake layers with frosting.

It’s shaping up to look more like a smash cake! Add your final layer of frosting to cover the whole cake.

Voila! Your cake is complete! Serve as is, or decorate it with toppings of your choice!

Without further ado, here’s the recipe and ingredients. Hope your child likes it as much as mine did!

The Recipe:

Ingredients:

Cake

  • 2 large bananas
  • 1 egg
  • 1/4 cup plain yogurt
  • 1 tsp vanilla
  • 1 1/4 cup flour (I prefer whole wheat, but you could also use white or spelt)
  • 1/2 tsp baking soda
  • 1 tsp baking powder

Frosting

  • 1 1/2 cup heavy whipping cream
  • 1 cup blueberries

Instructions:

Cake

  1. Preheat oven to 350F.
  2. Butter your cake pan(s) and lightly dust with flour, tapping out the excess.
  3. Mix the dry ingredients: flour, baking powder, and baking soda. Set aside.
  4. In a separate bowl, mash your bananas in the bottom (with a masher, a fork, your hand… whatever you’ve got). Then add the yogurt, egg, and vanilla. Mix these wet-ingredients together.
  5. Combine the dry and wet ingredients. Mix until just combined.
  6. Divide the batter in half and bake as two separate cakes in your buttered pan(s). See notes in “The Process” section above for more info on pan size. They take about 20-25 minutes at 350F. Take them out of the oven when a fork/toothpick inserted into the center comes out clean.
  7. Let the cakes cool.

Frosting

  1. Dump the blueberries in a blender and make a blueberry puree. I used a baby bullet for this step.
  2. Pour the whipping cream into a separate bowl and whip it with an electric mixer. Stop mixing when the cream reaches the desired consistency for frosting (about 10 minutes).
  3. Fold the blueberry puree into the whipped cream to create a sweetened and pretty blue-purple frosting! Feel free to add more blueberries for more color/flavor.
  4. Add decorations (optional). Top your masterpiece with a candle, blueberries, a hand-drawn smiley face, or whatever you’d like!

My Daughter’s Smash Cake

Because I can’t help myself, here are some photos of my daughter’s experience with her smash cake. She was very skeptical at first, but once she got into it, she was all about smashing it in her hands, smearing it on anything in reach, and shoveling it down her throat. A full-on sensory experience. 🙂 The cake was a perfect combination of messy and durable.
