Melt the ghee, butter or oil in a small, cold saucepan. Whisk together the ghee and xanthan gum. Pour in the cream a little at a time, while constantly whisking. Cook over medium-high heat until hot, but not boiling.
*If you wish to sweeten this pudding with monk fruit, organic sugar, or other sugar-free sweetener, add it to the cream before heating. **LorAnn Oils brand of banana extract is potent. Therefore, if you use a different brand you may need to use more. Add additional extract if desired.
