What Is The Best Flour To Use For Crust
Almond flour works great for this recipe. I found out of all the flours this offered the best texture and flavor for the bars.
It baked up nicely, and when you use a super fine flour you won’t have that gritty texture.
Now if you can’t find superfine almond flour at your store, you can make your own.
Take your almond flour and pulse it in your food processor. This is the best way to get a finer flour without having to buy it for this keto pecan pie bar recipe.
Sugar Free Pecan Pie Bars
And since you replaced your sugar with a sugar alternative sweetener, you have a sugar free dessert!
I get asked often if you can swap out sweeteners for a recipe. What I will say is you can try to swap but I can’t promise it will work.
Every sweetener has a different way it blends in with recipes, so swap dry sweeteners for dry, liquid for liquid and see how it goes.
Just measure properly!

Question:
Butter and sweetener with pecans...
Does this make a butter brickle/crunchy top, as opposed to a carmely chewy one?
Sarah Hardy
Yes, this makes a crunchy bar, instead of chewy.
Melissa
You might want to edit the instructions for the pecan layer to add that after removing the monkfruit and butter from the heat to let cool before adding the vanilla. I did not wait and was not thinking that room temperature vanilla would "explode" when I added it to the melted mixture. Luckily, I jumped back quickly enough to avoid any burns.
Holly
Sarah, any idea if I can use ghee instead of butter (to be dairy free). I don’t want to waste organic pecans if the milk solids are needed for caramelization or something. Thanks for answering.
ps-I really like your informative videos!
Holly
I watched your video on Glucci. I always pronounce it (GLUE-Key just because serene and pearl pronounce it that way lol). Anyways, how much of that do you normally add to a BIG pot of soup to thicken it up a little? And do you just sprinkle it in the pot like you said you did for other things or do you mix it with something first and then add it? Thank you!
Sarah Hardy
I always just sprinkle a little on top an stir well.
Vicky Lindsay
I’m wondering why erithritol in the crust and monk fruit in the filling? Can I use erithritol for both as I always have that on hand?
Thanks.
Vicky
Sarah Hardy
Yes, you can use erythritol for both!
Roberta Forbes
Is there a substitute for Monk Fruit?
Sarah Hardy
You can also use erythritol.
Teresa Nance
I cooked the crust for fifteen minutes and it is still soft like it isn’t done. Is that the way it is supposed to be?
Sarah Hardy
It should firm up as it cools. 🙂
Janie Marley
I tried these for the first time and will definitely be making them again! The flavors of both layers and textures make for a fantastic keto dessert option!! Thanks!!
