Prep and Cook Time
Total Time: 5 minutes
Prep Time: 2 minutes
Cook Time: 3 minutes
Yield
1 single-serving mug cake (approximately 4 inches in diameter)
Difficulty Level
Easy – Perfect for beginners and busy keto bakers alike
Ingredients
- 4 tbsp almond flour (finely ground for best texture)
- 2 tbsp unsweetened cocoa powder (high-quality Dutch-processed)
- 1 tbsp erythritol (or preferred keto-friendly sweetener)
- 1/4 tsp baking powder
- 1 large egg
- 3 tbsp unsweetened almond milk (or coconut milk)
- 2 tbsp melted butter (grass-fed preferred, for richness)
- 1/2 tsp vanilla extract
- Pinch of salt
Instructions
- prepare your mug: Lightly grease a 10-12 oz microwave-safe mug with butter or nonstick spray to ensure easy release and prevent sticking.
- Mix dry ingredients: In a small bowl,whisk together almond flour,cocoa powder,erythritol,baking powder,and salt until well integrated with no clumps.
- Combine wet ingredients: In another bowl, beat the egg, then stir in almond milk, melted butter, and vanilla extract until smooth and glossy.
- Incorporate wet into dry: Pour the wet mixture into the dry ingredients, folding gently with a spatula until the batter is uniformly dark and thick but spoonable. Avoid overmixing to keep the cake tender.
- Pour batter into the mug: Transfer the batter to your prepared mug,smoothing the top with the back of a spoon for even cooking.
- microwave cooking: Cook on high for 2.5 to 3 minutes. Watch closely after 2 minutes to avoid overcooking; the cake should be set but moist. Use toothpick testing if unsure-it should come out with a few moist crumbs.
- Cool briefly and enjoy: Let the cake cool for 2 minutes to finish setting and become fudgy. Relish directly from the mug or invert onto a plate for presentation.
Tips for Success
- For an ultra-moist texture, don’t substitute almond flour with coconut flour directly; coconut flour absorbs more moisture and requires different ratios.
- If your mug cake turns gum-like or too dry, reduce microwave time by 10-15 seconds or try adding a splash more almond milk next time.
- Swap erythritol with monk fruit sweetener for a smoother sweetness with less potential aftertaste.
- Make ahead prep: dry ingredients can be mixed in bulk and stored airtight; add wet ingredients fresh for rapid baking.
- Enhance gooeyness by stirring in a few sugar-free chocolate chips or a spoonful of nut butter before microwaving.
Serving Suggestions
Serve warm, crowned with a dollop of whipped heavy cream or coconut cream for luscious richness. Sprinkle with toasted sliced almonds or a light dusting of powdered erythritol for a gourmet touch. For an added flavor contrast, drizzle warm sugar-free caramel sauce or add fresh raspberries alongside for a pop of colour and tartness.Pair your keto mug cake with a cup of freshly brewed espresso or herbal tea for a divine experience.
