Combine all of the dry ingredients together. You can combine them in your mug right away or mix them first in a separate mixing bowl. Add in an egg and avocado oil, then stir the ingredients to combine.
Microwave your mug on high heat for 1 minute. You’ll know the mug biscuit is done when it looks puffed up and slightly darker around the edges. You can gently press down on the biscuit and feel that it’s done as well.
If you need to microwave the mug biscuit for longer, then do so, adding about 30 seconds each time until it is cooked. Once it cools for a minute, you can slip it out of the mug and slice.
Preheat a small nonstick skillet over medium heat. Crack the eggs one at a time into the skillet. Turn the heat down slightly if necessary to prevent the egg from browning too quickly and/or sticking. Season the eggs with a pinch of salt on each. Flip the eggs and cook until the desired doneness is achieved.
Slice the biscuit into three slices and top with the butter. Plate the eggs next to the biscuits and top with a pinch of black pepper, if desired. Serve immediately.
Serve immediately while it’s still warm and fresh. Taste and optionally add some more salt or pepper. These pair perfectly with your favorite low-carb vegetables or Greek yogurt.
