A rich, fudgy keto mug brownie ready in just 5 minutes! Single-serve, low-carb, and perfect for curbing those late-night chocolate cravings.

Ingredients

• 2 tbsp unsweetened cocoa powder

• 2 tbsp powdered erythritol

• 1/8 tsp sea salt

• 1.5 tbsp melted coconut oil

• 1 large egg

• 1/4 tsp vanilla extract

• 1 tbsp sugar-free chocolate chips (optional)

Directions

• Mix the dry stuff: In a microwave-safe mug, stir together cocoa powder, sweetener, and sea salt.
• Add the wet: Mix in melted coconut oil, the egg, and vanilla until smooth.
• Add chips: Fold in chocolate chips if you’re using them (do it, they’re amazing).
• Microwave: Heat on high for 60–90 seconds. It should puff up and look set but still moist.
• Cool & devour: Let it sit for a minute, then dig in with a spoon. Add a little whipped cream or pair it with Keto Chocolate Ice Cream for a next-level treat.

Notes

• Use a wide mug to avoid overflow.
• Adjust microwave time based on wattage.
• Tweak sweetener to match your preference.

Handy Little Tips for Mug Brownie Magic

Even though this recipe is super simple, a few quick tricks can make your brownie even better. Whether you’re all about the gooey center or love a firmer bite, these little tips will help you nail it every time:

• Use a big mug: A larger mug gives the brownie space to rise without spilling over.
• Watch the time: Every microwave is a bit different, start with 60 seconds and add 10-second bursts if needed.
• Customize the sweetness: Not all sweeteners are created equal, so feel free to adjust the amount to suit your taste.
• Try it with butter: Swapping coconut oil for butter gives you a richer, more traditional brownie flavor.
• Top it off: A little keto whipped cream, keto chocolate ice cream, or nut butter on top takes this treat to the next level.
