Every once in a while there is a need for instant comfort - this will do it. Originally I found a Mug Cake recipe on Facebook but have been unable to make it since Dx as it had the evil flour in it. Imagine my delight whilst trawling the web to find an adaptable replacement 
3-MINUTE (FLOURLESS and SUGARLESS CHOCOLATE) MUG CAKE
1 tablespoon oil/melted butter ...thinks... this could be a good use for Coconut Oil maybe??
2 tablespoons cocoa
Tiny pinch salt, optional
1 egg
½ tspn vanilla extract
2 tablespoons Splenda
1 tablespoon heavy cream
In a small microwaveable bowl microwave the butter for about 15-20 seconds on HIGH until completely melted. Whisk in the cocoa and pinch salt until smooth. Whisk in the egg until well blended then whisk in the remaining ingredients until you have a smooth batter. Microwave on HIGH 1 minute 30 sec. (Adjust to suit your device) Cool completely or serve warm and slightly gooey...with cream is nice.
