Prep and Cook Time
- Prep Time: 3 minutes
- Cook Time: 90 seconds
Yield
Serves 1 mug cake (single serving)
Difficulty Level
Easy – perfect for keto beginners and seasoned low-carb fans alike
Ingredients
- 3 tbsp almond flour (finely ground for smooth batter)
- 1 tbsp coconut flour (for added texture and binding)
- 2 tbsp powdered erythritol (or preferred keto-amiable sweetener)
- 1/4 tsp baking powder
- 1 large egg
- 2 tbsp unsweetened almond milk
- 1 tbsp melted coconut oil (or butter for richness)
- 1/2 tsp pure vanilla extract
- 2 tbsp sugar-free chocolate chips (optional but highly recommended)
Instructions
- Combine dry ingredients: In a microwave-safe mug, whisk together almond flour, coconut flour, erythritol, and baking powder until evenly mixed.
- Add wet ingredients: Crack the egg directly into the mug. Pour in almond milk, melted coconut oil, and vanilla extract. Stir vigorously with a fork or small whisk until you achieve a smooth, cohesive batter with no lumps.
- Fold in chocolate chips: Gently mix in the sugar-free chocolate chips distributed evenly throughout the batter for molten pockets of flavor.
- Microwave the batter: Cook on high for 90 seconds. Microwave powers vary, so start checking at 70 seconds-cake should spring back lightly to touch without being wet in the centre.
- Cool and enjoy: allow your keto mug cake to rest for 1-2 minutes; this helps it set perfectly and prevents burning your tongue with hot steam.
Tips for success
- Choose finely ground almond flour: Coarser almond flour can result in a crumbly texture rather than soft and fluffy.
- Adjust sweetness: Depending on your palatability, tweak erythritol amount or blend it with stevia for a sweeter bite.
- Watch your microwave wattage: Every microwave is different-if it cooks to fast, the cake may turn rubbery. If it’s undercooked, extend in 10-second bursts.
- Substitute fats: Coconut oil gives a subtle tropical note, but grass-fed butter adds decadence and depth.
- Make-ahead batter: Prepare the dry mix ahead of time; simply add wet ingredients and microwave for instant gratification.
- Flavor boosts: Enhance the batter with cinnamon, matcha powder, or a pinch of espresso powder for exciting flavor twists.
creative Toppings and Variations to elevate Your Keto Treat
- Whipped cream and crushed toasted pecans for textural contrast and creamy indulgence.
- Fresh raspberries or sliced strawberries paired with a drizzle of sugar-free chocolate sauce add vibrant freshness.
- Peanut butter swirl: Drop a teaspoon of natural peanut butter onto the batter before microwaving for an irresistible nutty surprise.
- Berry compote: Warm frozen berries with erythritol until syrupy, spooned generously over your mug cake.
- Coconut flakes and chopped pistachios sprinkle on top for a tropical,crunchy finish.
