Cook Time: 30 minutes
Cooling Time: 2 hours
Total Time: 3 hours 10 minutes


2 1/4 cups (300g) cake flour (preferably use a kitchen scale to measure or use scoop and level method to measure)
1 Tbsp (12g) aluminum-free baking powder
1/2 tsp salt
3/4 cup (170g) unsalted butter, at room temperature
1 1/2 cups (300g) granulated sugar
1/4 cup (60ml) vegetable oil
2 large eggs, whites and yolks separated, at room temperature
2 tsp vanilla extract
1/2 tsp almond extract
4 large egg whites
1 cup + 1 Tbsp (250ml) whole milk, at room temperature
1/2 cup (92g) rainbow jimmies sprinkles


Preheat oven to 350 degrees. Butter and line two 9-inch round cake pans. Line bottoms with parchment paper, butter parchment, dust with flour and shake out excess. Wrap pans with cake strips.
Sift cake flour into a medium mixing bowl. Add baking powder and salt and whisk together.
In the bowl of an electric stand mixer cream butter and sugar until very pale and fluffy. Scrape down sides and bottom of the mixer bowl with a rubber spatula.
Mix in vegetable oil. Then mix in the 2 egg yolks, scrape down mixer bowl. Blend in vanilla and almond extract. Set aside.
In a separate clean medium mixing bowl using an electric hand mixer whip 6 egg whites (2 from the whole eggs listed, 4 from egg whites listed) on high speed until medium-stiff peaks form (tips of peaks should just droop slightly).
Add 1/3 of the flour mixture to butter mixture in the stand mixer, mix just until combined. Add 1/2 of the milk and mix just until combined. Add another 1/3 of the flour mixture mix just until combined, followed by the remaining 1/2 milk mixture mixing just until combined. Add in the last 1/3 of the flour mixture and mix just until combined.
Remove bowl from the stand mixer. Add egg whites and sprinkles and gently fold the batter with a rubber spatula just until combined.
Divide mixture among prepared pans, pour and spread into an even layer.
Bake in the preheated oven until a toothpick inserted into the center comes out clean, about 30 – 35 minutes.
Cool in pan about 20 minutes, then run a knife around edges of the cake to loosen and invert onto wire racks to cool completely.
Once cool frost with buttercream frosting. If adding sprinkles over frosting add right away before it starts to develop a lightly dry outer crust. Store cake in an airtight container at a cool temperature (or chill for longer shelf life).

Recipe Notes

To soften butter faster I usually microwave in 4-second intervals then rotate between each interval until just soft with a bit of firmness, do not melt!
This will take about 60 minutes of resting at room temperature unless you’re in a warmer climate.
To bring eggs to room temperature faster place in a bowl, cover with warm water, rest 5 minutes. For egg whites place in a sealed container and place in a bowl of very warm water rest 5 minutes.
To bring milk to room temperature quickly warm in microwave until it reaches 70 degrees on an instant-read thermometer. It should only take about 30 seconds.
If there is a nut allergy almond extract can be omitted, increase vanilla to 1 Tbsp total.
