Alexa play ‘Birthday’ by Katy Perry! Funfetti cakes reminds me of birthday celebrations and Katy Perry. If you have a summer birthday without a funfetti cake…you’re not doing birthdays right! Funfetti is such a fun vibe and the best pop of color added to any dessert. Even if it’s not your birthday, this mini vanilla funfetti cake is small enough to be an after-dinner treat to enjoy between friends or family! This recipe is for two 6 inch cakes, layered, and coated in a sweet vanilla buttercream!

BUTTERCREAM TIPS
- Beat the butter first until it becomes fluffy, then add powdered sugar in small chunks.
- using softened butter is best
- Use milk or heavy cream
- heavy cream will help you get that thick, creamy texture, while milk will give you a fluffier texture.
- add your milk or cream slowly. you can always add more, but you can never take the milk out.
- Add strawberry extract (or any other flavored extract)
- this brings extra flavors and added sweetness to your buttercream
- Cover the bowl with a towel while mixing
- there are many times I’ve had powdered sugar flying everywhere when adding it to the mixer because it wasn’t covered
- The spatula test!
- this is a quick way to confirm that your frosting is the perfect consistency
- press a spatula into your frosting and pull it up.
- the frosting should be a stiff peak with a slight curl on the end
- if it’s too stiff add more milk, if it’s too thin, add more powdered sugar (1/3 cup at a time)

HOW TO MAKE THE BEST LAYERED CAKE
Room temperature ingredients: When your sweets are baking, air expands and helps to create a light tender result. They make baking so much smoother with the best tasting results!
Butter + Sugar: Cream together the butter & sugar until it turns fluffy. It’s important to not over-cream your butter. We suggest beating until both are combined & fluffy (1-2 minutes)
Level Cakes. If your cakes are domed, you can use a knife or a cake leveler to even out the cake. This would make the tops of the cake even for the layers. To get even layers without using a knife or a cake leveler, we use baking straps around the cake pans!
Stacking The Cake: Make sure the cakes are lined up properly. You wouldn’t want ‘leaning tower of Pisa’ style cakes!
Crumb Coat: This is a thin layer of buttercream around the cake to make a nice base for the real layer of butter cream. It’s called a crumb coat because it seals in all the crumbs of the cake so they don’t appear in the final buttercream layer of the cake. I like to chill my crumb coat in the fridge for 10-15 minutes before adding a clean, smooth layer of buttercream.

KEY INGREDIENTS:
Butter: Softened butter will add to this extremely fluffy I love to pair butter with sour cream because it brings out a softer, moist cake crumb.
Sugar: The sugar adds sweetness to the cake!
Eggs: The base structure of this cake is eggs! For a non dairy alternative, sub flax eggs, applesauce, or use Bob’s Red Mill Egg Replacer.
Sour Cream: Add sour cream to get a soft & moist crumb. You can sub full fat greek yogurt, dairy-free vanilla yogurt, or milk.
Vanilla Extract: This is our flavor component (in addition with bananas) For different flavors, add different extracts (almond, coconut, rum, etc).
Butter: Softened butter is the most important part to buttercream. Leave your butter out for 30-45 minutes for the best softened butter. A great substitute is vegan butter!
Powdered Sugar: Sift your powdered sugar before beating it with the butter. This will give you the best clump-free buttercream frosting!
