There’s nothing wrong with indulging in a decadent dessert from time to time—whether you’re on a romantic date or home alone with a glass of wine. Yep, we said it. But a single girl or guy left home alone with a freshly baked batch of cookies when a sugar craving strikes is a very dangerous thing. Be honest: One cookie always leads to four. Our answer? An indulgent single-serving dessert. You can have less but you can’t have more. From apple pie for one to chocolate fudge cake in a mug, these treats are crazy satisfying.
