Short answer
No, they share similar risks. Both cookies and cake are mildly risky for cats and should only be fed with extreme caution, if at all. The main dangers are the same: hidden ingredients like chocolate chips, raisins, or the artificial sweetener xylitol in sugar-free versions. A tiny accidental lick of a plain cookie is unlikely to cause harm, but intentionally feeding either is unnecessary and can lead to stomach upset or worse. Offer your cat a species-appropriate treat instead and keep human sweets out of reach.
