Add ¼ cup semi-sweet chocolate chips and 3 tbsp coconut oil to a microwave safe bowl and microwave for 30 seconds. Mix together melted oil and chocolate chips. It's ok if the chocolate isn't totally melted.
To the same bowl, add the ¼ c coconut sugar, ¼ c almond flour, Pinch of salt, a Splash of vanilla, and 1 egg. If you're using the collagen, you can add that too. Mix well to combine.
Split the batter between 2 mugs and microwave each one for 1 minute and 15 seconds (give or take 15 seconds, depending on how powerful your microwave is). Let it cool for a few minutes before digging in.To make it in one mug (a single-serve brownie), use a wider mug and microwave it for 2-3 minutes or until just set in the center.
