I love mug cooking- it's an awesome way to make a quick single serving snack, without heating up the house since they're cooked in the microwave. I'm not going to say this is gourmet cooking, but being able to whip up a fresh apple muffin in two minutes sounds pretty great!
1 tablespoon grass fed butter (or coconut oil)
2 tablespoon unsweetened applesauce
1/4 teaspoon vanilla
1 teaspoon maple syrup
3 tablespoons almond flour or 2 tablespoons coconut flour
1/2 teaspoon cinnamon
1/8 teaspoon baking powder
Pinch of salt
1 tablespoon apple, finely chopped
pinch of crumbled walnuts
pinch of cold butter
