Table of Contents

Ingredients (Serves 1)
- 2 tbsp almond flour (or oat flour for lighter texture)
- 1 tbsp unsweetened cocoa powder
- ½ tsp baking powder
- 1–2 tsp erythritol, stevia, or monk fruit sweetener
- 2 tbsp unsweetened almond milk (or any plant-based milk)
- 1 tsp coconut oil, melted
- 1 egg (or 1 tbsp flax/chia egg for vegan option)
- ¼ tsp vanilla extract
- Pinch of sea salt
Step-by-Step Instructions
- Combine Dry Ingredients: In a microwave-safe mug, mix almond flour, cocoa powder, baking powder, sweetener, and salt until uniform.
- Add Wet Ingredients: Stir in almond milk, coconut oil, egg, and vanilla extract until smooth and lump-free.
- Microwave: Cook for 60–90 seconds, depending on your microwave’s power. The cake should rise and look slightly moist on top.
- Cool Slightly: Let the cake cool for 1–2 minutes before digging in — this prevents burns and improves texture.
Pro Tips for the Perfect Mug Cake
- Molten Center: Add a teaspoon of peanut butter or a small chunk of dark chocolate in the center before microwaving for a gooey surprise.
- Fluffier Cake: Whisk the egg separately until frothy before mixing with dry ingredients to add extra air.
- Texture Variation: Swap almond flour for coconut flour (use less than half) for a different texture.
- Toppings: Top with Greek yogurt, berries, cacao nibs, or a drizzle of almond butter to enhance flavor and nutrition.

Variations for Every Taste
- Double Chocolate: Add 1 tsp unsweetened cocoa nibs or 70% dark chocolate chips for extra richness.
- Mocha Delight: Mix ½ tsp instant coffee or espresso powder for a coffee-flavored twist.
- Nutty Treat: Stir in 1 tsp chopped almonds or walnuts for crunch and healthy fats.
- Berry Infusion: Add 3–4 fresh or frozen raspberries for natural sweetness and a fruity punch.
- Spiced Chocolate: Sprinkle cinnamon, nutmeg, or a dash of chili powder to enhance flavor depth.
