Low-Carb Sugar-Free Lemon Curd Mini Tarts


Start to Finish: 40 minutes


  • 4 Vanilla Shortbread Collagen Protein Bars, crumbled
  • 3 eggs, room temperature
  • 1 tablespoon granulated stevia
  • 1/2 teaspoon vanilla extract
  • Zest of 1 Meyer lemon
  • 1/2 cup fresh squeezed juice of Meyer lemon (about 2 lemons)
  • 6 tablespoons unsalted grass-fed butter or Grass-Fed Ghee, melted
  • Pinch of Himalayan pink salt
  • Optional: Fresh organic blueberries to garnish


  1. Preheat oven to 250 degrees.
  2. Gather 8 muffin cup liners and divide collagen bar crumbs evenly into each cup. Spread and press crumbs firmly into the bottom of each cup using a spoon or fingers, shaping into tart/cookie shape. (Liner is important here in order to remove after baking.)
  3. Bake mini tart crust for 7 minutes, or until edges are lightly browned. Set aside to cool.
  4. Combine lemon juice, zest and melted butter in a small bowl. Stir to combine and set aside.
  5. Whisk eggs, vanilla, stevia, and salt in a medium saucepan using a coated whisk or spatula.
  6. Place on low-medium heat, stirring continuously, until the mixture thickens and the color lightens (about 7-8 minutes). Stirring continuously prevents eggs from scrambling.
  7. Add lemon juice and butter mixture to the egg mixture one spoonful at a time, continuing to stir.
  8. The mixture will lighten in color and begin thickening into a pudding-like texture. Stir until the mixture is fully heated (3-4 additional minutes).
  9. Using a sieve or cheesecloth, remove the pan from heat and pour the mixture through the strainer into a glass storage container, pushing the liquid through the holes as necessary. Dispose of remaining solids and allow the strained lemon curd to cool for 5 minutes.
  10. Carefully remove the cooled tart shells from liners and top with 1 tablespoon of lemon curd. Garnish with 1-2 blueberries, if desired.

Recipe notes: Sugar-free lemon curd is best served fresh. It will store in the fridge for up to 2 days, but chilling will change its consistency due to the butter. After pulling out of the fridge, allow the mixture to sit, covered, on the counter for a few minutes to soften the butter.
