Chocolate Protein Mug Cake Recipe
Introduction
This Protein Mug Cake is a quick and satisfying chocolate treat perfect for busy days or a midday snack. Packed with protein and rich cocoa flavor, it’s easy to make right in your mug using common pantry ingredients.

Ingredients
- 1 tbsp unsalted butter (can substitute ghee for paleo or coconut oil for dairy-free)
- 1/4 tsp vanilla extract
- 3 tbsp Besti Monk Fruit Allulose Blend
- 2 tbsp whey protein powder (or any protein powder of your choice; choose a different option for dairy-free)
- 1 1/2 tbsp Dutch processed cocoa powder
- 1 1/2 tbsp Blanched almond flour
- 1/4 tsp baking powder
- 1 large egg
- Sugar-free dark chocolate chips (optional)
- Sugar-free whipped cream (optional)
Instructions
- Step 1: Melt the butter in a mug by heating it in the microwave for about 30 seconds.
- Step 2: Stir in the vanilla extract until combined.
- Step 3: Add the Besti Monk Fruit blend, protein powder, cocoa powder, almond flour, baking powder, and the egg. Mix well until smooth and even on top.
- Step 4: Microwave for 60 to 75 seconds until a toothpick inserted in the center comes out clean but the cake remains moist. Alternatively, bake in a large ramekin at 350°F (175°C) for 10 to 15 minutes.
- Step 5: If desired, top with sugar-free dark chocolate chips and whipped cream. For melty chocolate chips, microwave the cake an additional 5 to 10 seconds before adding whipped cream.
Tips & Variations
- For a dairy-free version, substitute butter with coconut oil and use a plant-based protein powder.
- If you don’t have Dutch processed cocoa, natural cocoa powder can work but may change the flavor slightly.
- Add a pinch of instant espresso powder to enhance the chocolate flavor.
- Try stirring in chopped nuts or berries for added texture and taste.
Storage
Protein mug cake is best enjoyed immediately but can be stored in an airtight container in the refrigerator for up to 2 days. Reheat in the microwave for 15 to 20 seconds before eating to warm it through.
