This 4 inch cake recipe is the perfect size for just a handful of people to share! It also makes a perfect vanilla smash cake or mini birthday cake. It's deliciously light and fluffy, easy to make, and super cute!
There’s just something so adorable about mini desserts isn’t there?! The same way that mini donuts are somehow so much cuter than regular donuts, this mini cake is somehow cuter than a regular sized vanilla cake!
The base of this 4 inch cake recipe, as well as the vanilla buttercream, is adapted from my recipe for vanilla cupcakes. This recipe uses a reverse creaming method, where the butter is mixed into the dry ingredients, and it gives it such a light and fluffy crumb!

Ingredient Notes
- Flour: This 4 inch cake recipe calls for all-purpose flour, and has not been tested with gluten free flour.
- Milk: Regular milk, or dairy free milk works great. I like to use soy milk in my cakes.
- Butter: Regular or vegan butter works great in both the cake and the buttercream recipe.
- Oil: Be sure to use a neutral oil like canola, sunflower, or grapeseed oil.
- Vanilla Extract: Because vanilla is the main flavor of this cake, I highly recommend using real vanilla extract if you can. It makes a huge difference!
Step By Step Instructions
Note: Full ingredient measurements and instructions can be found in the recipe card at the bottom of this page.
Step One: Preheat the oven to 350°F and prepare three 4 inch round cake pans. Spray the inside with cooking spray, then cut out pieces of parchment paper so that they fit in the bottom of each pan (do not skip this step!). Set the pans aside.
Step Two: Add flour, salt, baking powder, and sugar to the bowl of a standing mixer or handheld mixer. Whisk them together until combined.
Step Three: Add the butter into the bowl of the dry ingredients and beat until the butter is incorporated and the mixture resembles the texture of sand.
Step Four: Pour in vanilla extract, milk, and oil and mix again. Lastly, add in the egg and mix until just combined (don't over-mix).
Step Five: Divide the cake batter between the three cake pans and bake for 18-24 minutes, or until a toothpick inserted in the middle of the cakes comes out clean.
Let the cakes cool in the pan for 10-15 minutes, then remove them from the pan (by running a butter knife or offset spatula around the edges and then flipping the cake upside down onto a cooling rack). While the cakes cool, make the buttercream.
Step Six: In the bowl of a mixer, beat the butter (and vegetable shortening if using) together until combined, then add in vanilla extract and food coloring (if using).
Add in the powdered sugar, ¼ cup at a time until your desired consistency is reached. If the buttercream is too thick, you can add ½ tablespoon of milk in at a time, thinning it out as much as you'd like. If buttercream is too thin, add in more powdered sugar ¼ cup at a time.
Assembling the Mini Cakes
To assemble the cakes, you can either make a naked cake, do a crumb coat or you can just frost the outside of the cake in the traditional way.
To make a crumb coat, add a thin layer of frosting to the outside of the cake, scraping off the excess with a bench scraper (this is called a crumb coat). Then place the cake in the freezer for 20 minutes then add another layer of frosting.
If you'd rather skip the crumb coat, you can simply frost the outside of the cake in one layer then decorate with sprinkles or as desired. Have fun with it!
I like to use white food coloring! There are a few other tricks out there but this is my go-to.
Absolutely! Just add the sprinkles directly into the batter as the last ingredient.
I haven't tested this cake gluten free flour so I can't say for sure how it will turn out. If you’d like to try it out I would suggest using gluten free 1-1 baking flour.
Can I make these mini cakes in a larger pan?
You sure can! This recipe makes enough batter for two 6 inch round cakes.
Expert Tips
- Properly measure your flour - If you over-measure your flour, the cake could turn out dry and crumbly. It is very easy to over-measure your flour, so I strongly recommend weighing it with a $10 kitchen scale or using the scoop and level method.
- Line your pans with parchment paper! It’s the best way to prevent sticking. You should also grease the sides of the pans.
- Careful not to over-mix your batter! Over-mixing the cake batter will affect the texture of the cakes.
Storage and Freezing Instructions
The cake can be stored covered at room temperature for 3-4 days.
You can also freeze the cake layers if you want to make this cake ahead of time. Let them cool completely, then tightly wrap each individual cake layer in parchment paper, then aluminium foil. Freeze in ziploc bags for up to 3 months, then let them thaw at room temperature.
You can store leftover buttercream in an airtight container in the freezer for up to 2 months. Thaw it in the fridge then re-whip it using a handheld or standing mixer before frosting the cakes.

I am working out of town for my birthday but the airbnb i'm in had a small kitchen so I went out and bought everything i needed to make myself a personal sized birthday cake. It was too much to eat in one sitting but I can't say it lasted the whole weekend either. so tasty
Gabby
Hi Raina! I love that! I'm so glad to hear that you enjoyed the cake - and happy birthday! 😀
Kierti Panjwani
Please give option for egg I don't want to add .measurements are for 1 cake of 4 inch pan Right?please clarify !
Gabby
This recipe makes 3 round 4 inch cakes. If you aren't using egg you could try replacing it with 1/4 cup of oil or applesauce, but I haven't tested that myself so I really can't say for sure how it would turn out.
