Reply What hapened with my cupcakes?

They definitely look under baked to me. Most white colored batters should be a light golden color when finished. Test several cupcakes with a toothpick or cake tester/skewer and the toothpick should come out clean with no batter stuck to it. Lastly, most cupcakes will spring back when you gently press on the top of it. If it leaves a finger print/doesn’t spring back to shape they are not finished yet.
Good luck!
