90 second chocolate mug cake keto recipe by Chef Rita

90 Second Chocolate Mug Cake Keto: The Perfect Low-Carb Treat in Minutes

A rich and fudgy 90 second chocolate mug cake keto dessert that’s low-carb, moist, and ready in minutes the ultimate guilt-free comfort treat made with cocoa, almond flour, and butter.

  • Total Time: 3 minutes 30 seconds
  • Yield: 1–2 servings

Ingredients

Scale

2 tablespoons unsalted grass-fed butter, coconut oil, or ghee
1 ½ tablespoons cocoa powder
2–3 tablespoons xylitol, erythritol, or allulose (to taste)
1 large egg
2 tablespoons almond flour
1 tablespoon golden flaxseed meal or finely ground psyllium husk
2 teaspoons coconut flour
½ teaspoon baking powder
Pinch kosher salt

Instructions

Melt the butter in a medium microwave-safe bowl for 25 seconds.
Whisk in the cocoa powder and sweetener until well combined.
Add the egg and mix until smooth.
Stir in the almond flour, flaxseed meal, coconut flour, baking powder, and salt until the batter thickens.
Spoon the batter into a mug and place a paper towel under it to catch any overflow.
Microwave on high for 70–90 seconds, depending on wattage (80 seconds at 1000 watts is ideal).
Let cool for two minutes before topping with whipped cream or a sugar-free chocolate drizzle.

Notes

This recipe makes one large serving (or two smaller ones).
If you use allulose, increase the amount slightly for sweetness since it’s less sweet than erythritol.
For an even fudgier texture, reduce the cook time by 10 seconds.
You can replace almond flour with coconut flour (use 1/3 the amount).
