Birthday cake crumbs are a quick and easy way to add classic and nostalgic birthday cake flavor to your favorite desserts. These sweet, crunchy crumbs taste just like funfetti cake and come together in just 15 minutes. Sprinkle them over cakes, cupcakes, cookies, ice cream, or use them as a delicious cake filling.
In a medium mixing bowl, whisk together the cake flour, granulated sugar, light brown sugar, baking powder, and salt until well combined.
Add in the vegetable oil and vanilla extract and stir until the dry and wet ingredients are fully incorporated and large clusters form.
Add in the rainbow nonpareil sprinkles and stir until they are well dispersed throughout the mixture. Break up any larger clusters with a spoon.
Spread the birthday cake crumb mixture onto the prepared baking sheet pan. Bake the crumbs for 10 minutes. After baking, cool the birthday cake crumbs to room temperature and then break them up into small crumbs.
