Recipe Tips

- Add chocolate chips for a more indulgent treat! They melt beautifully inside.
- Use a larger mug to prevent overflow while microwaving.
Ingredient Swaps
- Almond flour → Coconut flour (use ⅓ the amount since coconut flour absorbs more moisture).
- Swerve → Monk fruit sweetener or erythritol (adjust to taste).
- Cottage cheese → Greek yogurt (for a slightly different texture).
- Chocolate chips → Chopped keto-friendly chocolate bar for variety.

Storage Tips
This single-serving recipe is best enjoyed fresh, but if you have leftovers:
- Store in an airtight container in the fridge for up to 24 hours.
- Reheat in the microwave for 10-15 seconds before eating.
- Do not freeze—mug brownies tend to dry out when frozen.
