Sound of a cupcake hitting the floor, frosting-first

SPLAT

Think of the noise a soft, messy object makes when it lands heavily—like a paintball or overripe fruit dropping from a height.

This clue plays on the onomatopoeic sound you’d hear if a cupcake—especially one landing frosting-side down—hit the ground with a messy, squishy thud. "Splat" perfectly mimics that wet, splattering noise, like frosting smacking the floor in a way that’s both funny and a little tragic. The humor comes from the mental image of a once-perfect treat meeting a very undignified end.
