Ingredients

Scale

For the Perfect Keto Mug Cake:

  • 3 tbsp almond flour (super fine grind, blanched)
  • 2 tbsp unsweetened cocoa powder (Dutch-processed preferred)
  • 2 tbsp erythritol or sugar-free sweetener (granulated erythritol, stevia blend, or monk fruit sweetener)
  • ¼ tsp baking powder (fresh)
  • Pinch of salt
  • 2 tbsp unsweetened almond milk (or keto-friendly milk alternative)
  • 1 tbsp melted butter (cooled slightly)
  • ½ tsp vanilla extract
  • 1 large egg yolk

Optional Flavor Upgrades:

  • 1 tbsp sugar-free chocolate chips (Lily’s or ChocZero)
  • ¼ tsp instant coffee granules
  • ⅛ tsp cinnamon
  • 1 tsp almond butter
  • 1 tsp cream cheese (softened)

Decadent Toppings:

  • 1 tbsp sugar-free whipped cream
  • 1 tsp chopped nuts (pecans, almonds, or walnuts)
  • Fresh berries (raspberries or blackberries)
  • Sugar-free chocolate syrup
  • Unsweetened coconut flakes (toasted)
  • Sea salt flakes

Instructions

  1. Preparation & Mug Setup: Choose a microwave-safe mug with 12-16 oz capacity. Lightly grease the mug if desired to help with removal. Have all ingredients measured and ready to speed up the process.
  2. Combine Dry Ingredients: In the mug, whisk together almond flour, unsweetened cocoa powder, erythritol (or your chosen sweetener), baking powder, and a pinch of salt until evenly mixed with no lumps.
  3. Mix Wet Ingredients: In a small bowl or directly in the mug (if preferred), whisk together unsweetened almond milk, cooled melted butter, vanilla extract, and egg yolk until smooth and well combined.
  4. Create the Batter: Pour the wet ingredients into the dry ingredients in the mug. Whisk vigorously until the batter is completely smooth, thick but pourable, and free of lumps.
  5. Add Optional Mix-ins: Gently fold in any optional add-ins such as sugar-free chocolate chips, instant coffee granules, cinnamon, almond butter, or cream cheese if using.
  6. Level the Batter Surface: Tap the mug lightly on the countertop to settle the batter and smooth the surface for even cooking and a professional look.
  7. Microwave Cooking: Microwave the mug cake on high power for 60 to 90 seconds. Start at 60 seconds and check the rise and firmness. The cake should be set but still slightly moist in the center and spring back lightly when touched. Avoid overcooking to prevent a rubbery texture.
  8. Cooling: Let the mug cake cool for 30 to 60 seconds before eating, as the inside will be very hot immediately after microwaving.
  9. Final Touches & Serving: Add desired toppings such as sugar-free whipped cream, chopped nuts, fresh berries, sugar-free chocolate syrup, toasted coconut flakes, or a sprinkle of sea salt flakes. Serve warm immediately for best texture and flavor.

Notes

  • Use a microwave-safe mug between 12-16 oz to accommodate the batter rise without overflow.
  • Room temperature egg yolk results in a smoother, less rubbery texture.
  • Fresh baking powder is essential to achieve proper rise in the short microwave cooking time.
  • Adjust microwave time based on your microwave wattage; lower wattage requires additional 10-15 seconds.
  • Do not fill the mug more than two-thirds full to prevent overflow during cooking.
  • Use high-quality Dutch-processed cocoa powder for richer chocolate flavor and smoother texture.
  • Experiment with optional mix-ins and toppings for variety while keeping carbohydrate count low.
  • For dairy-free version, substitute melted butter with coconut oil and almond milk with coconut milk.
  • Consume immediately after cooking for optimal texture; reheating is possible in short bursts but may affect cake quality.
