Step-by-Step Instructions
Whisk Dry Ingredients in Mug
In a 10- to 12-oz microwave-safe ceramic mug, whisk flour, sugar, cocoa powder, baking powder, and salt together with a small fork until no lumps remain.
Add Wet Ingredients
Pour in milk, melted butter (or coconut oil), and vanilla extract. Whisk gently until a smooth, thick, glossy chocolate batter forms.
Insert Molten Chocolate Center
Drop a tablespoon of dark chocolate chips (or one dark chocolate truffle) right into the center of the batter. Do not stir; let it sink into the center.
Microwave to Perfection
Microwave on HIGH for 65 to 75 seconds (depending on microwave wattage). The top should look just set while the center remains gooey.
Top and Enjoy Warm
Let rest for 1 minute. Top with a cold scoop of vanilla ice cream or a swirl of whipped cream and chocolate shavings. Dig in warm!
