Why You’ll Love This 6-Inch Vanilla Cake Recipe

My daughter just turned 5 and this year, we decided to have a small celebration with just our small family 4. I still wanted to carry on the tradition of making her cake from scratch, so I decided to bake a smaller 2-tier 6 inch cake. It turned out so fluffy and delicious, and you can even turn it into a funfetti cake with sprinkles if you wish!

All the ingredients for this mini cake are fairly simple and the cake comes together quickly and easily. The creamy buttercream frosting keeps the cake moist and tender, and we’ve been enjoying it all week.

Ingredient Notes

Cake

• butter: Make sure it’s melted then cooled, so it doesn’t cook the eggs while mixing.
• avocado oil: Or any neutral flavored oil
• eggs: Use room temperature eggs
• granulated sugar
• milk: Any milk will work. I’ve used regular whole milk and almond milk, and both turned out wonderful.
• vanilla extract
• gluten free all-purpose flour: Use gluten free flour with xanthan gum – I like Bob’s Red Mill. If you are not gluten free, you can use regular all-purpose flour.
• baking powder
• sea salt
• sprinkles: Sprinkles are optional but a fun addition if you want to turn this small vanilla cake into a funfetti cake. I used naturally dyed sprinkles, so the colors bled a bit. I recommend using regular rainbow sprinkles.

Buttercream Frosting

• butter: Use softened butter at room temperature.
• milk: At room temperature
• vanilla extract
• sea salt
• powdered sugar
• food coloring: If you want to decorate with different colored frosting, you can use food coloring dye the frosting.

Step-by-Step Instructions

You’ll need two 6-inch cake pans for this recipe. Line the bottom with parchment paper, and grease the sides with cooking spray. Preheat the oven to 350 degrees F.

Expert Tips

• You can easily make this dairy free by using, vegan butter and dairy free milk. It’ll still turn out delicious!
• Either salted or unsalted butter will work in both the cake and the frosting.
• There’s enough buttercream frosting to frost the entire cake, plus enough to decorate it if you wish.
• Make sure to cool the cake completely before frosting. If you aren’t frosting right away, you can store the cake layers in the fridge overnight, each layer wrapped tightly in a plastic wrap. Once frosted, let it sit at room temperature before slicing and enjoying.
• This is a 2 tier cake, but you can easily make this 1 tier or 3 tier. Each layer is 6 servings, so adjust the serving size to how many layers you want (6 servings for 1 tier, 18 servings for 3 tiers).

Storage Tips

• Once frosted, you can store at room temperature covered for 3-4 days. The frosting will keep the cake tender and moist. You can also refrigerate for up to a week.
• You can also freeze frosted or unfrosted cake.
  • Once frosted, cut into slices, then freeze on a baking sheet overnight. The next day, wrap each slice in a plastic wrap then freeze for up to 3 months.
  • Wrap each unfrosted cake layer tightly in a plastic wrap, then freeze for up to 3 months. You can frost frozen or defrosted cake.
• Unused buttercream frosting can be stored in an airtight container for a week. Whip before using to fluff it up again. You can also freeze for up to 3 months. Place in a resealable bag, or if using a freezer safe container – place a parchment paper on top to keep from ice crystals from forming. Defrost in the fridge, then re-whip before using to frost.
