If your phyllo is frozen, place in the fridge to defrost overnight. The next day, prepare your filling by chopping the halva and placing in a bowl along with the grated apple, walnuts, sugar, cinnamon, oats and cocoa powder. Stir to combine.
Take the phyllo out of its packaging and place horizontally in front of you on your work surface.
Cut into three even pieces and stack-up. Place a slightly damp towel on top to prevent them from drying out.
Drizzle one sheet of phyllo with olive oil and fold up the bottom end about 2 inches. Place a heaping tablespoon of filling at the base, fold the sides and roll up into a cylinder.
Place seam side down on a parchment-lined baking sheet. Repeat with the remaining sheets of phyllo.
Brush the tops of the flutes with olive oil and place in your preheated oven and bake for 15 minutes or until golden.
Remove from the oven and allow to cool.
Serve on a plate or platter, drizzle with honey then dust with icing sugar and ground cinnamon and serve.
