My precious girl turned one last weekend! I seriously cannot believe how fast the past year has gone by. It seems like it was just the other day that we were bringing her home from the hospital, and making a pit stop along the way to pick up a big box of hot malasadas to celebrate. 😉

Have you ever had a malasada before? I’d never had one until we moved out here to Hawaii. They are basically fried pieces of delicious sugary dough. Uh-mazing! But I digress…

We decided to keep her actual birthday pretty low key and just stayed at home to let her play with her new toys, which my son and I were SO excited about. Probably more than her. 😉

He was excited to have presents around to open and play with, and I was excited about GIRL presents! She got her first Cabbage Patch Doll, which I couldn’t wait to get for her since I loved mine when I was little.

Plus, Babyland General Hospital (where the Cabbage Patch Dolls are born) is just a little ways up the road from my hometown in Cleveland, Georgia. I’m SO looking forward to taking my kiddos there one day!

We are having a birthday party for her in a couple of weeks with a luau theme, since she’s our little Hawaiian-born baby.

I decided that I still wanted to do a little something special for her actual birthday, and I really wanted to try my hand at making her a smash cake. I had never made one before, and I had never really decorated a cake before either, aside from slapping on some icing with a spatula and going shake crazy with some sprinkles. 😉

I was ready to give it my best shot, though, and I ended up being pretty proud of my work! It actually isn’t that hard at all, and while my cake certainly isn’t anywhere near the quality of a professional’s, I was still very happy with it, and so was our little birthday girl.

How to make a Smash Cake

1. If you want to make a two layer smash cake (like I did), search your cabinets for two small, round, glass pyrex bowls. The ones I used were one quart each. You can use two small casserole dishes or other kinds of bowls as well, just so long as they are oven-safe! Grease and flour them both well.

2. Prepare the Simple Vanilla Cake batter according to directions below. Fill each of the glass bowls about 3/4 the way full with batter. I used the remaining batter to make a dozen cupcakes as well. Bake and allow to cool completely. Once cool, loosen the cakes gently from the sides of the bowls by carefully running a knife around the outside edges. You will want to flatten out the tops of your cakes, which you can do by cutting a very thin layer off the top of each with a knife.

3. Prepare your frosting. I used my Vanilla Buttercream Frosting

recipe and added a little pink gel food coloring. Spread a thin layer on the top of one of your cakes, then turn the other cake upside down and place on top.

4. Now you’re ready to pipe on your icing! Take a piping bag and add whatever tip you would like to use to decorate with. I decided to try putting little roses all over mine, and I used a Wilton 1M tip. To make filling your piping bag easier (and less messy!) stick the end of your bag inside of tall glass (I used a tall, wide mouth mason jar) and pull the top part of the bag down and over the edges. MUCH easier to fill. 🙂

5. I covered mine in roses, which were DEFINITELY NOT perfect, but I was still really happy with it! Especially since it was my first attempt, I was okay with it not being perfect. Your baby is going to LOVE digging into their cake, and they are not going to care one little bit how fancy it’s decorated, so just HAVE FUN with it! If you want to make roses, take the tip of your icing bag, squirt and move in a circular motion, swirling around in a circle from the center. I covered the top of the cake in these swirls first before attempting the sides.

6. Continue covering the cake by with the same pattern down the sides. The sides were definitely more challenging for me! Just take your time, and remember how much your sweet baby is going to love it. 🙂 For any open spaces, I just gave a simple squirt of frosting to fill.

7. For the the little topper, I tied some baker’s twine around two paper straws (that came in a pack I bought from Target). I LOVE fun straws, and I was so excited that I had some turquoise ones since I decided to do her cake in a pink and turquoises theme. Next, cut out some small triangle shapes from scrapbook paper and tape them to the string, like I’ve shown below. I used three little triangles to spell out the word “one” but you could also make your baby’s name! My little girl’s name is pretty long, so I decided to stick with the word “one” instead. 🙂 I simply wrote the letters on the opposite side with a black sharpie, but you could also use letter stickers!

8. Carefully stick the two straws into your cake, pushing down until both are level and to your liking. Then stand back and admire your finished product!

I hope this helps you a bit if you’re interested in making a smash cake for a special little one in your life! It’s really not hard at all, and is actually a lot of fun! Like I said, mine is not perfect. My icing decorating skills could probably use some improvement, but overall I was happy with it.

If I can make one that looks somewhat decent, then I know y’all can, too!

Oh, and here’s the recipe for the simple vanilla cake! Enjoy. 🙂

Recipe: 1st Birthday Smash Cake Tutorial + Simple Vanilla Cake

Yield: 12 servings
Prep Time: 20 minutes
Cook Time: 35 minutes
Total Time: 55 minutes
Celebrate your little one's first birthday by making a fun and yummy smash cake! It's easier than you might think to make one at home, especially with this simple vanilla cake recipe.
This recipe makes two small smash cakes.


  • 2 cups granulated sugar
  • 1 cup unsalted butter,, softened
  • 4 eggs
  • 2 Tablespoons vanilla extract
  • 3 cups all-purpose flour, (could also be made with cake flour)
  • 3 1/2 teaspoons baking powder
  • 1 1/2 cups milk, (I used whole milk)


  • Preheat oven to 350 degrees. Grease and flour baking pans, or line muffin tin with cupcake liners.
  • Using an electric mixer, beat the sugar and butter together over medium speed for 5-8 minutes. Add in the eggs, one at a time, beating well after each addition. Stir in the vanilla.
  • Combine the flour and baking powder in a medium sized bowl.
  • Alternate adding the dry mixture and the milk to the batter, beginning and ending with the dry mixture. Beat until just combined.
  • Pour mixture into prepared baking pans. See notes below for baking times.
  • Once baking time is complete, transfer baking dishes to a wire rack to cool. Once completely cool, remove cakes from baking dishes and frost with Easy Buttercream Frosting and enjoy!


*This recipe is enough to fill two (1 quart) Pyrex baking bowls, as well as 12 cupcakes. It is also enough to make one 9x13 cake. Bake the two small cakes for about 35-40 minutes, or until toothpick in center is clean. I baked both of mine together on a cookie sheet. Bake cupcakes for about 18-20 minutes. I have not baked the 9x13 cake, but think it would probably be about the same as the two small ones. Just keep an eye on your cakes and check them periodically.
