Why did my Chocolate Peanut Butter Mug Cake become hard?

Overcooking is usually the culprit. Microwave it for only 60–70 seconds. Also, avoid using eggs, which can make single-serve cakes rubbery and dense.

How long do chocolate peanut butter cups last?

Homemade peanut butter cups last 1–2 weeks in the fridge in an airtight container. Store-bought versions typically last months due to preservatives.

How do you keep mug cake from getting rubbery?

Use oil instead of butter for more moisture, skip the egg, and mix your batter thoroughly. Overcooking will also make it tough—watch the time closely.

How to make a successful mug cake?

Use a large mug, skip eggs, mix ingredients well, and microwave just until set. Toss in some chocolate chips or swirl a bit of peanut butter on top to boost both texture and taste.
