There are many great resources for recipes that are compatible with the ketogenic, low carb way of eating. One of the sites to which I often return is Linda's Low Carb Menus & Recipes. It's very straight forward and easy to follow. Some of the recipes are not strictly ketogenic but ones that are marked with an asterisk, indicating they are 'induction friendly', are. That's a reference to the original Atkins program where one would spend the first 2 weeks in induction, or very low carb. The ketogenic diet is essentially never leaving induction. So navigate towards those induction friendly recipes and you'll be good to go.
But there are a couple of recipes I've found in other places and have tinkered with. A favorite in our house is a version of a low carb almond cookie. I don't remember where I found the original recipe but I believe it called for butter - I use coconut oil - and didn't use an egg. I do.
Here's a video of my method of making them. The recipe is below that, along with the nutritional info.
Keep in mind, almonds are not on the allowed food list (found here) and as I wrote in this post, I tend to avoid them. Lovely Mate can tolerate them and remain in ketosis. So, if you can do so as well, enjoy!
