Ingredients

Crust

  • 1 cup all-purpose flour or whole wheat, or oat flour*
  • cup butter solid, cut into chunks**
  • ¼ cup granulated sweetener of choice I used erythritol
  • tsp salt

Filling

  • 4 eggs
  • 1 cup granulated sweetener of choice
  • cup freshly squeezed lemon juice
  • 2 Tbsp lemon zest
  • ¼ cup all-purpose flour or whole wheat, or oat flour*

Optional Topping

  • powdered sugar once chilled
  • *I have made a version of this recipe using oat flour in the past and it turned out well though all-purpose flour works best!
  • **I’ve also made this crust with solid coconut oil in the past though I prefer butter.

Instructions

  • Preheat oven to 350°F (180°C).
  • Add crust ingredients to food processor and pulse together for about 30 seconds, until mixture holds together when pressed.
  • Press crust into a square 8x8-inch glass baking dish that’s sprayed with cooking spray. (A metal dish may leave a metallic flavor with lemon bars.) Poke all over surface of crust with a fork to aerate.
  • Bake for 14-17 minutes, until lightly golden brown. Set aside and allow to cool slightly.
  • Squeeze lemons to get ⅔ cup juice.
  • Combine all filling ingredients, whisking to integrate thoroughly. Pour on top of your slightly cooled crust.
  • Return to the oven for 35 minutes, until the filling has gelled and is cooked through.
  • Allow to cool completely—rest 2 hours on the counter at room temperature, then another 1-2 hours in the fridge.
  • Dust with powdered sugar and slice into bars. Best served chilled!
  • Store in an airtight container in the fridge for 5-7 days.

Notes

Nutrition provided for healthy lemon bars made with erythritol – a naturally occurring sugar alcohol that is 80% as sweet as regular sugar, but with only 5% of the calories and a low glycemic index.
Though erythritol contains 4g of carbohydrates per 1 tsp, it has zero net carbs. Studies have shown that these carbs do not affect blood sugar in the same manner as regular sugar, and erythritol may actually help to lower blood sugar. 
So, the nutrition provided accounts for the net carb content after removing the non-digested carbs from erythritol. The total carb content, accounting for the carbs from erythritol, would be 23g per lemon bar.
