First, prepare your syrup or Keto honey substitute by following this recipe Then bake 6 large pieces of Keto pita bread using a wide pan. Follow this recipe: Do not overcook them, it will be enough to cook them for 1 minute from each side.
Using an electric mixer, beat egg yolks with butter and stevia until you get a shiny emulsion. Add chopped walnuts, almonds and spices.
Line a baking sheet with a parchment paper and grease it with some butter or coconut oil. Place 2 pita bread pieces at the bottom. Cover with half of the filling. Then place two more pita bread pieces and tap with your fingers. Repeat the process once again.
Using a very sharp wet knife gently cut out the baklava shapes. You will be able to cut 8 medium baklavas. Don't worry about the corners, they will taste really good!
Place the Keto baklava in the oven and bake it at 160ºC (320ºF) for 10 minutes.
Pour the Keto honey substitute in a deep saucepan and heat it so that it returns to liquid form. Remove the baklava from the oven and pour the syrup all over, but make it very slowly and gradually.
Decorate with walnuts or almonds and serve warm or at room temperature.
