Melt butter in a large mug or baking dish in a microwave.
Add all dry ingredients including coconut flour, garlic and baking powder, dried parsley, black pepper, and Himalayan pink salt then mix with a fork.
Add wet ingredients including 1 egg, water, grated cheese and heavy whipping cream and mix well until combined.
Microwave for 2½ -3 minutes then allow to cool for 2 minutes.
Enjoy straight from the mug or slice and enjoy with thinly spread butter.
Recipe Notes
If you wish to use an oven instead of a microwave, then mix the ingredients in a small baking dish and bake in an oven for 10 minutes at 360°F until the bread rises and a toothpick comes out clean.
No need for the full 10 minutes if you want a moist, gooey melted cheese on the inside.
The bread slides out of the mug so smoothly making it easy to slice and spread butter if you wish to increase fat intake.
If you find the baked recipe doe not hold well together then microwave for an extra 30 seconds or bake a few minutes longer.
If it turns out a little dry then slightly reduce the time baked or in the microwave.
Feel free to experiment with keto mug bread and substitute with different types of herbs and spices, flours, creams, etc.
