Grain-Free Microwave Brownies

Our oven has been broken for a while now, and I really miss my homemade gluten-free and/or grain-free treats. I love the ability to still be able to indulge in a dessert and completely control what I put in it, especially in concerns to the carb content, sugar content, and grain content. I also love being able to decide what type of oil I add to my food.
So far, I've found two microwave recipes online, and one no-bake recipe. The no-bake recipe is for chocolate coconut cookies. One of the microwave recipes is for a "mug cake" that I honestly did not like... and the latest recipe I've found is for grain-free brownie bites by The Detoxinista.
I LOVE the grain-free brownie bites recipe. They hit the spot wonderfully! The original recipe has directions for the oven, but I was able to figure out how to cook it in the microwave.
After combining all of the ingredients together in a bowl, poor the batter into a microwave-safe baking dish. Microwave on high for 5 minutes, and let it sit in the microwave for another couple minutes before handling (it will be very hot!). Take out of the microwave and cool either on the counter or in the refrigerator for another ten minutes... and there you go!
