Ingredients You’ll Need

Simple ingredients that pull their weight.

• All-purpose flour – Just a small amount, no heavy lifting.
• Unsweetened cocoa powder – Brings real chocolate flavor.
• Zero-calorie sweetener – Granulated or powdered works here.
• Baking powder – Gives lift, not sadness.
• Milk (low-fat or almond milk) – Keeps it moist.
• Vanilla extract – Rounds out the chocolate.
• Pinch of salt – Makes everything better.
• Optional: Sugar-free chocolate chips or a dusting of cocoa powder on top.

Step-by-Step Instructions

1. Grab a mug.
   Use a microwave-safe mug that holds at least 12 oz. Trust me.
2. Mix dry ingredients.
   Add flour, cocoa powder, sweetener, baking powder, and salt. Stir well.
3. Add wet ingredients.
   Pour in milk and vanilla. Mix until smooth and lump-free.
4. Level the batter.
   Smooth the top so it cooks evenly.
5. Microwave.
   Cook for 60–90 seconds. Start with 60 and check doneness.
6. Rest briefly.
   Let it sit for 30 seconds to finish setting.
7. Eat immediately.
   Mug cakes wait for no one.

Common Mistakes to Avoid

• Overcooking.
  This turns cake into sponge. Stop early if unsure.
• Using a small mug.
  Overflowing chocolate lava is messy and tragic.
• Not mixing properly.
  Dry pockets ruin the vibe. Stir thoroughly.
• Skipping the salt.
  Chocolate needs balance, even in tiny desserts.
• Expecting bakery cake.
  This is a mug cake, not a patisserie masterpiece. Adjust expectations.

Alternatives & Substitutions

• Gluten-free:
  Use oat flour or gluten-free all-purpose flour.
• Extra fudgy:
  Add a teaspoon of chocolate chips (still stays close to 100 calories).
• Mocha version:
  Add a pinch of instant coffee. Chocolate loves caffeine.
• Protein boost:
  Replace part of the flour with protein powder and add a splash more milk.
• Vegan:
  Use plant-based milk—already egg-free, so you’re good.
