Does chocolate peanut butter cake need to be refrigerated?

Not right away. If you're eating your mug cake peanut butter chocolate within a couple of hours, there's no need to refrigerate it. If you need to store it for later, wrap it tightly and place it in the refrigerator for no more than 24 hours. When you're ready to enjoy it again, simply warm it in the microwave for about 10 to 15 seconds.

Why did my mug cake fail?

Many mug cake mishaps boil down to three common issues: cooking it too long, mismeasuring ingredients, or using a mug that's too small. For the best results, measure everything carefully, start by microwaving for 60 seconds, and choose a 12-ounce mug to prevent spillage.

How to make mug cake not rubbery?

A rubbery mug cake usually means too much flour or overmixing. Measure the flour carefully, using only what's needed, and stir just until the ingredients come together. Peanut butter and oil help keep it soft, so don’t skip them.

Why did my mug cake turn rubbery?

Microwaving too long is the most common cause. Even 10 extra seconds can dry it out. Keep an eye on your mug cake and start checking it around the 60-second mark to avoid drying it out or overcooking. Also, be careful not to overmix the batter, as this can activate the gluten and result in a dense, chewy texture.
