Lemon Cream Tart – It’s So Good! (Low Carb & Keto)

A creamy lemon curd tart bursting with tartness and flakey buttery almond pastry crust. This dessert is low carb, sugar-free, gluten-free and keto-friendly.

Ingredients

Scale
  • 2 cups almond flour
  • 3 Tbsp coconut flour
  • 4 Tbsp unsalted melted butter
  • 1 large egg
  • ¼ cup powdered allulose (a sugar-free alternative)
  • 4 large eggs
  • 4 large egg yolks
  • 1 cup of lemon juice (fresh)
  • 1/4 cup heavy cream
  • 1 cup of butter cubed
  • 1 1/4 cups allulose (test your lemons if they are very tart, add more sweetener)

Instructions

  1. Preheat oven to 350F
  2. Blend almond flour, coconut flour, allulose, and melted butter in a food processor.
  3. Add 1 egg and blend until the mixture starts to pull away from the side of the food processor bowl.
  4. You may need to add a Tbsp of water, depending on the dryness of your almond flour. If the mixture is not coming together, add the water.
  5. Form the tart crust into a disc and place it in the fridge for about 30 minutes. This makes it easier to handle.
  6. Roll out the dough between two sheets of parchment paper, adding a touch more almond flour if it starts to stick.
  7. Spread the tart dough out in your tart pan ( 9 inch round, 8-inch square, or 4.5x 14 rectangle) making sure to press into the side of the pan, and cover any holes that form while you're pressing. This takes a bit of patience, just keep pressing and spreading until your tart crust is spread evenly with no breaks.
  8. Pierce the crust with a fork and bake for 10-12 minutes until golden. Keep an eye out because almond flour tends to darken very quickly.
  9. Let the crust cool.
  10. Pour an inch of water into the bottom of a medium-sized saucepan and heat to a low simmer.
  11. Add eggs, egg yolks, lemon juice, allulose, and heavy cream into a separate heat-safe bowl.
  12. Place the bowl over the pot of simmering water and cook until the mixture coats the back of a spoon. This can take up to 15 minutes. Use a whisk and stir constantly while cooking to avoid burning.
  13. Once the mixture thickens, add the butter in cubes one at a time and whisk until fully melted.
  14. Add the filling to the cooled tart crust.
  15. Cool the dessert to room temperature.
