This easy classic birthday cake with sprinkle buttercream is the recipe you’ll come back to again and again. It’s simple enough for a beginner baker but impressive enough for a party, with a soft, tender crumb and creamy, colorful frosting that comes together in under two hours using ingredients you probably already have.
Room temperature ingredients are essential for best results. If you forgot to soften butter, cut it into small cubes and let sit for 15 minutes, or microwave in 10-second bursts. For clean slices, chill the cake for 30 minutes before cutting. The cake can be stored at room temperature for up to 3 days or frozen for up to 3 months. Sprinkles may bleed color after a day or two, creating a tie-dye effect.
