Make a Pumpkin Mug Cake Keto Friendly
To me, part of living a ketogenic lifestyle long term is finding low-carb replacements for the desserts I love. I used to live for sugary pumpkin goodies throughout the fall.
Now, I can still enjoy pumpkin treats in moderation using keto friendly ingredients. I also find that moderation is so much easier with high fat foods. Where I used to go back for seconds and thirds of a pumpkin cake, I am full and satisfied after one keto mug cake thanks to the fats.
