These Gluten-Free Lemon Bars are made with an almond cookie crust and topped off with a sweet but tart lemony topping!



Almond crust

Lemon topping

  • 1 cup of sugar 
  • 2 tbsp cornstarch 
  • 1/2 cup lemon juice (freshly squeezed) 
  • 2 eggs 
  • 1/4 cup coconut milk (full-fat from a can) 
  • zest of one lemon


  1. Mix the almond crust ingredients together in a bowl, then evenly spread the crust in an 8×8 inch pan lined with parchment paper. 
  2. Bake in the oven at 350 degrees F for 8-10 minutes.
  3. While the crust bakes, prepare the lemon topping by whisking the topping ingredients together in a bowl until smooth. 
  4. Remove the crust from the oven and pour the topping over the crust while it is still hot. 
  5. Reduce the oven temperature to 300 degrees F and bake for 20-25 minutes. The edges should be set but the bars should still be a bit jiggly in the center.
  6. Let cool on the countertop, then place in the fridge for at least 2-3 hours until set. 
  7. Cut into squares and enjoy!


Use freshly squeezed lemons. please DO NOT use bottled lemon juice! Fresh lemon juice makes all the difference for a delicious lemon bar.

Store these bars in the fridge. It’s best to eat these within 48 of baking them, otherwise, the crust can start to get a bit soggy. (These are really best enjoyed the same day you make them!)

Top these bars with powdered sugar for a touch of extra sweetness!
