1 ¼ cup Granulated Allulose Sweetener 1 cup if using an allulose/monkfruit blend, or other cup-for-cup sweetener.
½ cup Almond Flour
½ cup Vanilla Flavoured Whey Protein Powder
2 tablespoon Coconut Flour
¾ teaspoon Xanthan Gum
½ teaspoon Baking Powder
½ teaspoon Salt
8 tablespoon Unsalted Butter melted
3 Large Eggs
⅓ cup Fresh Lemon Juice
Zest from Two Lemons

Preheat oven to 350F (180C). Grease an 8"x 8" square cake pan with vegetable shortening or baking spray. I like to spray it, then line it with parchment paper.
In a large bowl, combine almond flour, protein powder, coconut flour, xanthan gum, baking powder, and salt.
Add melted butter, eggs, lemon juice and lemon zest to the bowl of dry ingredients, beat until smooth and well combined.
Transfer batter to prepared baking pan, spreading evenly.
Bake for 25-30 minutes, or until JUST set in the middle. Do not over cook, or you’ll have dry bars!
Allow bars to cool completely, before making the glaze:
Whisk together powdered allulose, lemon juice, and salt. It should be very thick. Heat in the microwave for 15-20 seconds, and whisk again - it should be thick but spreadable.
Spread frosting over cooled bars, allow to set up before slicing and serving.

45 grams of the per-serving carbs come from the sugar alcohol - plus 1 gram from fiber - so the net carbs on each bar = 3.
