Preheat the oven to 350F.
In a blender, standing mixer, or food processor, add coconut oil, mayo, vanilla, peppermint extract, and eggs together. Mix very well.
Add the heavy whipping cream.
In a separate mixing bowl, whisk together your dry ingredients until there are no clumps. Add your dry ingredients to the wet ingredients, making sure it's all incorporated.
Once your mixture is mixed, it is ready to be divided. Place your mixture into your donut mold. I made six donuts, though you could just as easily have seven from mixture.
Bake for 30 minutes.
To prepare your ganache, warm your heavy whipping cream in a saucepan with the sweetener until the sweetener dissolves. Then add your chocolate chips and let them melt. Once the chocolate is melted, stir in the peppermint extract.
Take your donuts and dip the tops into the ganache to coat them. Add toppings, if desired, right away before the ganache sets.
Store in a container in the fridge for up to one week.
