Lupin Flour Brownies – The Best Keto Brownie Recipe Ever

Sharing this post!

I had a craving for brownies and I threw together these ingredients not expecting much. But these Lupin Flour Brownies will become my basic keto brownie recipe forever! They were so good.

Usually, I make keto brownies with almond flour because I love the texture I get but I’ve been trying to swap out almond flour for lupin flour where I can. Lupin flour has less calories and less carbs and gives a softer texture to baked goods.

If you love a more dense, chewy kinda brownie, you may want to stick with almond flour. This brownie was delightfully soft and absolutely perfect for my craving.

Unfortunately, I didn’t have any sugar-free chocolate chips or dark chocolate bars on hand to include in my recipe. I know that would have kicked things up to where I needed them to be and added the fudginess I love in brownies.

But these hit the spot so well that I can’t wait to make them again with the extra chocolate included. So if you have those on hand, go ahead and add them in!

If you’re lost and not sure how to get started with the keto diet, this meal plan is for you. It’s a fool-proof guide to winning at the high-fat, low-carb lifestyle.

To make this keto brownie, you’ll need:

I added nuts to mine because I love nuts but you don’t have to. I know that’s a polarizing ingredient in brownies. Let me know if you love these as much as I do! And don’t over-bake them!

Without the chocolate chips or nuts, this recipe comes out at just 0.5g of net carbs per serving! That there is the reason why I will forever make my brownies with lupin instead of almond flour. They taste great too!

There are 83 calories in just one serving so make sure not to overeat these still. I baked it in an 8×8 pan and cut it into 16 servings. If you don’t have lupin flour, simply swap that out for almond flour at the same amount.
