Funfetti Cake Layers
1
Preheat the oven to 350 degrees (180 degrees F).
2
Grease and line three 6 inch cake pans with parchment paper.
3
Soak cake strips in ice cold water.
4
In the bowl of a stand mixer fitted with the paddle attachment, combine the flour, sugar, baking powder, and salt.
5
Cut up the butter into small cubes and add to the dry ingredients. Mix on low speed until it resembles wet sand.
6
Add the oil, milk, and vanilla, and mix until just combined.
7
In a separate bowl, whip the egg whites to medium peaks. Gently fold it into the batter with a rubber spatula until just combined.
8
Lastly, add the sprinkles and mix until evenly distributed.
9
Divide the cake batter between the prepared pans. Wrap the outsides of the pans with the cake strips.
10
Bake the cake layers for 40-45 minutes or until a tooth pick inserted comes out clean.
11
Turn the cakes out onto a wire rack to cool completely. Once cool, wrap in plastic wrap and leave at room temperature or in the freezer until ready to decorate.
Swiss Meringue Buttercream
1
Wipe the bowl of a stand mixer and whisk attachment down with white vinegar.
2
Add the egg whites and sugar to the bowl and whisk until fully combined.
3
Place over a small saucepan of simmering water, and whisk frequently until it reaches 160 degrees F or until the sugar is completely dissolved and the mixture no longer feels grainy.
4
Move the bowl over to the stand mixer with the whisk attachment. Whisk on medium-high speed until medium peaks form.
5
Add the vanilla and continue whisking until stiff peaks form.
6
Turn the mixer down to low speed, and wait until the meringue cools down to at least 85 degrees F.
7
Cut the butter into cubes and add to the meringue a few pieces at a time, allowing them to fully incorporate before adding more.
8
Once all of the butter is added, it may look curdled, but keep beating for a few more minutes and it will come together.
9
Once the buttercream has mostly come together, change the whisk attachment to the paddle and keep mixing on low speed until homogenous and smooth.
Assemble
1
Place the first cake layer on the cake stand. Add three 3 tablespoon scoops of buttercream and spread into an even layer. Place the second cake layer on top and repeat.
2
Spread an even layer of buttercream on the sides, then chill in the fridge for at least 10 minutes.
3
To the remaining buttercream, mix in 2 tablespoon of jimmy sprinkles until evenly distributed.
4
Remove the cake from the fridge and apply a thicker layer of buttercream to the sides.
5
Lastly, pipe buttercream along the edges of the cake as desired.
