Steps
Preheat oven to 350° Fahrenheit. Grease or line cake pans with parchment paper.
Add oats to a food processor or blender and blend into a flour. You can also use oat flour if you have it. Combine with the rest of dry ingredients.
In a separate bowl, combine all the wet ingredients together.
Combine dry and wet ingredients and mix until everything's well incorporated.
Evenly distribute the batter into three 5 inch cake pans. Bake for 25-30 minutes, until inserted toothpick comes out clean.
Let the cakes cool slightly in the pan for about 5 minutes before transferring to a wire rack to cool completely.
In the meantime prepare the frosting of choice(see note).
Slice the rounded top off of each cake to create a flat surface. Add dollops of frosting to first layer of cake and spread evenly. Place the second layer on top and repeat. You can go a step further and frost the entire cake.

Melanie Ong on 2025-11-27 (5 stars): It is supposed to be a 5-inches or 4-inches? It looks like 4-inches in your video and the pan link is also 4-inches?
Lisa M on 2025-10-25 (5 stars): I do have oat flour. What would the measurements be for that because I imagine the 2 cups of rolled oats blended up would not be 2 cups because of density.
Dana on 2025-10-24 (5 stars): My baby LOVED this, thank you so much for the recipe!
Lindsay on 2025-10-22 (5 stars): Hi Min!
Just wanted to say thank you so much for all your recipes. Your site and your newsletter are my go to when looking for new recipes for our family; everything has been delicious! I made this cake for our little one's first birthday and now I am planning to make it again for his second. It is perfect! We've made it for a few family birthdays in between, too!
I am planning to make a second batch into cupcakes for the party and I am wondering if you have a suggestion for making them chocolate? Would you recommend cutting down on some of the dry ingredients to add in cocoa powder, or possibly increasing some of the wet ingredients? Would love your thoughts.
Thank you again for sharing your recipes!
Monika on 2025-10-17 (5 stars): Made this baby smash cake for my daughter’s first birthday, and it was a big hit! I had 20 cm tins, so I doubled the recipe, and it worked perfectly. The cake was soft, moist, and just the right amount of sweetness. She loved it — highly recommend this recipe for a first birthday!
Sage on 2025-10-03 (5 stars): Can’t wait to make it this weekend! How much of the freeze dried strawberries would I mix in with the Greek yogurt for the frosting? Side note - my little one loves your egg cups! Appreciate these simple recipes SO much!
Tiffany Watson on 2025-10-01 (5 stars): Thank you so much for this recipe! I made this for my son's 1st birthday last weekend and he loved it. All the adults too. Will be saving this in our recipe folder. :)
