Instructions
For the Funfetti Cake
Preheat the oven to 325 degrees, and prep a 9x13 sheet pan/dish with shortening/spray/goop/nonstick. Set aside.
In a large bowl, whisk together all the ingredients except for the cake mix and sprinkles. Sift in the cake mix, then gently fold in the sprinkles until combined. Spread into the prepared 9x13 pan and bake for 20-14 minutes. Let cool.
For the Buttercream
In the bowl of a stand mixer, whip up the butter until it's light and fluffy, about 2 minutes. Add in the salt, vanilla, and heavy cream and whip up again to combine. Add in the powdered sugar and whip up on low speed until combined, then on high speed for 2 minutes to lighten the texture.
Split the buttercream into 4 bowls and tint three of the bowls pink, red, and light green using the gel coloring. Add the buttercream to piping bags fitted with the following piping tips: 1M (large star), 1A (large circle), 6B (large french tip), #125 (pedal/ruffle), #32 (smaller star). You can make the colors any tips you'd like, but here's what I did: Red: 1MPink: 1A Light Green: #125 and #32White: 6B
One by one, pipe on rosettes, swirls, drop stars, and ruffles in a random pattern all over the top of the cake. Sprinkle on the silver dragees.
