• Wash hands thoroughly for 20 seconds before you start cooking.
• Put the flour, erythritol-stevia sweetener, baking powder, and salt in the mug and stir to combine.
• Add a Tablespoon of water, yogurt, melted butter, maple syrup, vanilla, and half of the chocolate chips.
• Mix all ingredients together so that no dry or wet spots remain. Then, beat together for a few more times.
• Top with remaining chocolate chips. Now, pour a teaspoon of water over the batter and chips.
• Microwave at 80 to 90% power for about 1 minute and 30 seconds. The top should be just set. If the center is still wet, microwave in 10-second intervals on 100% power until it is done.

  It will continue to cook after you take it out of the microwave. A toothpick inserted in the center should come out with a few crumbs clinging to it.

  (Be careful of overcooking. You don't want a tough, rubbery cake!)
• Let sit for a minute or two and cool slightly before eating. Top with a splotch of whipped cream. Vanilla ice cream is also delicious on the cake!

Oven Baking Instructions

• Preheat oven to 350 F.
• After mixing the batter (follow the recipe through step 5), pour it into a ramekin coated with baking spray. Place it on a tray in the center of the oven and bake for 12 to 15 minutes.

  A toothpick inserted in the center will come out clean or with just a few crumbs clinging to it.
• Let cool for about 5 minutes and then enjoy topped with whipped cream or ice cream.
