💡Tips
1. Choose the right mug
Pick a microwave-safe mug that’s bigger than you think you need. The cake will rise as it cooks, so use a mug that’s at least 12 ounces (about 350ml) to prevent overflow.
A wider mug works better than a tall, narrow one because it allows the cake to cook more evenly. If you’re not sure if your mug is microwave-safe, look for a label on the bottom or stick to ceramic or glass mugs. Avoid using mugs with metallic paint or trim, as these can cause sparking in the microwave.
2. Mix it well
When you’re mixing the ingredients, take your time to really blend everything together. Use a fork or a small whisk to beat the egg first, then add the other ingredients one by one, mixing well after each addition.
Pay special attention to the cocoa powder – it can sometimes form clumps. Keep stirring until the batter is smooth and there are no dry patches or lumps. This might take a minute or two, but it’s worth it for a smooth, even cake.
3. Let it cool
It’s tempting to dig in right away, but give your mug cake a few minutes to cool down. This does two important things: it allows the cake to finish setting, improving the texture, and it lets the flavors develop more fully.

FAQ
1. Can I use crunchy peanut butter instead of creamy?
Yes, you can use crunchy peanut butter. It will give your mug cake some extra texture with bits of peanuts throughout. Just make sure it’s a keto-friendly peanut butter without added sugars.
2. My mug cake turned out dry. What went wrong?
A dry mug cake usually means it was cooked too long. Microwaves vary in power, so the cooking time in the recipe is just a guide.
Next time, try reducing the cooking time by 10-15 seconds. Remember, it’s better to undercook slightly than overcook – the cake will continue to set as it cools.
3. How can I add other flavors to this mug cake?
You can add a drop of peppermint extract for a chocolate-mint flavor, or a bit of orange zest for a chocolate-orange cake. A sprinkle of cinnamon can add warmth, or you could add a small handful of chopped nuts for extra crunch.
