Ingredients
  

Filling

  • 1 kg apples after coring about 6 medium, a mix of tart and sweet, cut into 2 cm chunks; peeling is optional
  • 1 tbsp lemon juice
  • 1 1/2 tsp ground cinnamon

Topping

  • 120 g rolled oats about 1 1/2 cups
  • 60 g walnuts about 1/2 cup, roughly chopped
  • 1/2 tsp ground cinnamon in total 2 tsp, 5.2 g
  • A pinch of salt 1 g
  • 60 g unsalted butter
  • 3 tbsp honey 63 g
  • To serve: Greek yogurt optional

Instructions
 

  • Heat the oven to 190°C (170°C fan). Have ready a baking dish of about 20 x 25 cm, or 2 litres.
  • Toss the apples with the lemon juice and 1 1/2 tsp cinnamon and spread them in the dish.
  • Blitz 40 g of the oats in a blender or chopper for a few seconds to a coarse flour; it helps the topping hold together. Mix it in a bowl with the rest of the oats, the walnuts, 1/2 tsp cinnamon and the salt.
  • Melt the butter with the honey in a small pan over low heat, just until liquid. Pour it over the oat mixture and stir until everything is coated and starts to clump.
  • Scatter the topping over the apples, leaving some larger clumps. Bake for 35-40 minutes, until the topping is deep golden, the juices bubble at the edges and a knife slides easily into the apples. If the top browns too fast, cover it loosely with foil for the last 10 minutes.
  • Let it rest for 10 minutes before serving; the juices thicken as it cools. Serve warm, with Greek yogurt if you like.
