Ingredients
- 1 scoop (30 g / 1 oz) Chocolate Whey or Casein Protein Powder
- 1 Tbsp (5 g / 0.18 oz) Unsweetened Cocoa Powder
- 1/4 tsp (1 g / 0.04 oz) Baking Powder
- 1-2 tsp Sweetener of choice (e.g., Erythritol, Stevia, or Monk Fruit)
- 3 Tbsp (45 ml / 1.5 fl oz) Milk (Dairy or non-dairy like Almond Milk)
- 1/4 tsp Vanilla Extract (optional)
- 1 square (10 g / 0.35 oz) Dark Chocolate (essential for the molten center)
Step-by-step Preparation
- Combine Dry Ingredients: In a microwave-safe mug (roughly 12 oz capacity), whisk together the protein powder, cocoa powder, baking powder, and sweetener. Use a small fork or whisk to ensure there are no lumps, particularly with the protein powder.
- Add Wet Ingredients: Pour in the milk and vanilla extract (if using). Mix thoroughly until a thick, uniform batter forms. Avoid overmixing; stirring just until the dry ingredients are incorporated will keep the cake tender. The batter should be thick, similar to brownie batter.
- Insert the Lava Core: Take the solid square of dark chocolate and gently press it into the center of the batter. Ensure the batter completely surrounds the chocolate piece, hiding it just below the surface. This chocolate will melt into the “lava” core.
- Microwave Magic: Place the mug in the microwave and cook on high for 60 to 90 seconds. **Cooking Tip:** Start with 60 seconds and check the consistency. The edges should be set, but the center should still look slightly damp and soft. For a truly molten center, aim to slightly *undercook* the cake. (Note: Cooking time varies significantly based on microwave wattage. A 1000W microwave usually requires about 75 seconds.)
- Serve Immediately: Carefully remove the hot mug using oven mitts. Allow it to cool for about 30 seconds before digging in. When you pierce the center, the molten chocolate will flow out.

Storage
This Molten Lava Protein Mug Cake is best enjoyed immediately while it is still warm and the center is liquid. If you absolutely must store leftovers, cover the mug tightly and refrigerate for up to 2 days. Be aware that the cake texture will become denser and the molten core will solidify upon cooling. To reheat, microwave the cake for 15-20 seconds until warm, but the lava effect may be slightly diminished compared to the fresh preparation. Freezing is not recommended.
Conclusion
This 90-second lava cake is proof that healthy eating doesn’t mean boring eating. For an extra touch of luxury, serve your warm mug cake with a spoonful of Greek yogurt or a scoop of low-carb vanilla ice cream. If you want to customize the flavor, try swapping out the vanilla extract for a few drops of peppermint extract, or add a teaspoon of instant espresso powder to the dry mix for a rich mocha depth. Enjoy your perfectly portioned, protein-packed chocolate escape!
