Expert Tips for Hot Cocoa Mug Cake
• Mix Thoroughly: Ensure all dry ingredients are fully combined to prevent clumps, which can lead to an uneven texture in your Hot Cocoa Mug Cake.
• Check Your Mug Size: Use a mug that’s at least 12 oz to prevent overflow while cooking. A too-small mug can cause a messy kitchen and a sad dessert!

Absolutely! You can use any brand of hot cocoa mix that you prefer. Just ensure that it’s a powder form, as this will help achieve that rich chocolate flavor in your Hot Cocoa Mug Cake. Some mixes may contain extra sugars, so consider adjusting the granulated sugar in the recipe accordingly for taste.

What if my mug cake turns out too dry?
Don’t worry, it happens! If you find your cake a bit dry, try adding a touch more vegetable oil or hot water in your next attempt.

This helps to retain that moist, tender texture that makes a mug cake special.
