Hi, I'm not personally looking for low carb or keto recipes, but I have gluten-free pals that I'm making (chocolate chess and apple) pies for. I didn't have enough coconut flour so I added some sweet rice flour and homemade oat flour to get the amount of flour correct, also used coconut sugar as my sweetener, worked fabulously! Thanks for the recipe backbone!

I was experimenting with whey protein in the other crust which makes the texture lighter.

You can use cold lard and cut into the dry ingredients with a food processor.

You can use the sweetener conversion calculator for other options. You may need to add something like whey protein to make up for the missing bulk if using a concentrated sweetener.

So, if I wanted to use just stevia (not a blend) how much do I use and what other ingredients would I need to adjust?

Would you then add COLD lard (I keep mine in the freezer) and pulse in a food processor with the coconut flour and sweetener?

Walnut flour should work in an all nut flour recipe like this almond flour pie crust recipe.
