Ingredients
  

Crust + Crumble

  • 1 1/2 cups almond flour
  • 2 Tbsp coconut flour
  • 1/4 cup + 2 Tbsp Swerve or monk-fruit blend
  • 1/8 tsp baking soda
  • 1/4 tsp xanthan gum
  • 2 pinches salt
  • 5 Tbsp unsalted butter cold, cubed

Filling

  • 3 medium zucchini peeled, seeded, chopped
  • 4 Tbsp unsalted butter
  • 1 tsp cinnamon
  • 2 Tbsp Swerve
  • 2 Tbsp lemon juice
  • 1 tsp vanilla extract
  • 1/8 tsp xanthan gum

Instructions
 

  • Prep the pan: Preheat oven to 350°F. Line a 6×6 or 7×7 pan with parchment.
  • Make the crust: In a mixing bowl, combine almond flour, coconut flour, sweetener, baking soda, xanthan gum, and salt. Cut in cold butter until crumbly.
  • Press 2/3 of the dough into the prepared pan to form the base. Refrigerate the rest for the crumble topping.
  • Pre-bake crust for 10–12 minutes, just until the edges look golden. Cool.
  • Make the filling: In a saucepan, melt butter and add chopped zucchini, cinnamon, sweetener, lemon juice, and vanilla. Cook 15–20 minutes until softened and reduced.
  • Sprinkle in xanthan gum and stir until thick.
  • Assemble: Spread filling over baked crust. Crumble the reserved dough on top.
  • Bake again for 15–18 minutes, until topping is golden.
  • Cool completely and chill 1 hour before slicing.

Notes

Why this matters: Cold butter keeps the crust tender and creates that shortbread texture. Rachel’s Real-Talk: These bars are great make-ahead desserts and slice cleaner when chilled.
