Fudgy dairy-free chocolate mug cake
Impossibly rich and fudgy, this single-mug chocolate cake goes from craving to spoon in under five minutes — no dairy, no nuts, no excuses.

4m
- 120 g all-purpose flour
- 40 g dutch-process cocoa powder
- 100 g granulated sugar
- 1 tsp baking powder
- ¼ tsp kosher salt
- 160 ml oat milk
- 60 ml vegetable oil
- 1
In a small mixing bowl, whisk together the flour, cocoa powder, sugar, baking powder, and salt until evenly combined with no streaks of cocoa remaining.
Tip: This makes enough dry mix for 4 mug cakes. You can store the leftover dry mix in an airtight container for up to a month.

For each mug cake, scoop 80g of the dry mix into a microwave-safe mug. Add 40ml oat milk and 15ml vegetable oil. Stir vigorously with a fork until the batter is smooth and no dry pockets remain — about 30 seconds of mixing. The batter should look glossy and thick, like brownie batter.
Tip: Scrape the bottom corners of the mug to catch hidden flour pockets.

Microwave on high for 70-90 seconds. The cake is done when the top looks set and slightly matte but the center still has a faint jiggle — it will firm up as it cools. If the surface still looks wet and shiny after 90 seconds, add 10 seconds at a time.
Tip: Microwave wattages vary. A 1000W microwave hits the sweet spot at about 75 seconds; lower-wattage models may need closer to 90.

Let the mug rest for 60 seconds — the residual heat finishes cooking the center into a fudgy, molten texture. Eat straight from the mug with a spoon.
Tip: Keeps as premixed dry mix in an airtight container at room temperature for up to 1 month. The baked cake is best eaten immediately — it firms up as it cools.
