4 tbsp gluten-free all-purpose flour blend Shop
4 tbsp granulated sugar Shop
2 tbsp unsweetened cocoa powder Shop
1/4 tsp baking powder Shop
1/8 tsp salt
3 tbsp milk (dairy or non-dairy)
2 tbsp melted butter or coconut oil Shop
1/2 tsp pure vanilla extract Shop
1-2 tbsp chocolate chips (optional) Shop

Instructions

1 In a microwave-safe mug (about 12-14 oz capacity), whisk together the gluten-free all-purpose flour blend, granulated sugar, unsweetened cocoa powder, baking powder, and salt. Ensure there are no clumps of dry ingredients, which should take about 1 minute.
2 Add the milk, melted butter or coconut oil, and pure vanilla extract to the mug. Stir with a fork until the batter is smooth and well combined, scraping down the sides of the mug to incorporate all the dry bits, about 1-2 minutes.
3 If using, gently fold in the chocolate chips into the batter. Be careful not to overmix at this stage.
4 Microwave on high power for about 1 minute and 30 seconds to 2 minutes, or until the cake is set and a toothpick inserted into the center comes out mostly clean with moist crumbs attached. Cooking time may vary depending on your microwave's wattage.
5 Allow the mug cake to cool in the mug for at least 2-3 minutes before enjoying. The cake will continue to firm up as it cools, making it easier to eat without burning your mouth.

Tips & Notes

Microwaves vary. Start at 1 minute 30 seconds and add 15-second bursts until just set.
Use a large mug, as step 1 says, so the batter doesn't overflow.
A slightly underdone center is best. The cake keeps cooking as it rests.
