Ingredients

Base;

  • 1 Cup Butter, Melted (220g)
  • 3 Tbsp. Maple Syrup (75g)
  • 2 tsp Vanilla Extract
  • 3 Large Eggs
  • 1 and ½ Cups Milk
  • ⅓ Cup Caster Sugar (Superfine Sugar) (75g)
  • ⅓ Cup Brown Sugar (65g)
  • 2 and ½ Cups Self-Raising Flour (450g)
  • ½ tsp Cinnamon

Apples;

  • 3 Granny Smith Apples (or cooking apples)
  • 1 Tbsp. Maple Syrup
  • 2 tsp Cinnamon
  • 1 tsp Mixed Spice (or nutmeg)

Crumble Topping;

  • 1 Cup Walnut Pieces, Roasted (100g)
  • ½ Cup Rolled Oats (45g)
  • ¼ Cup All Purpose Flour (30g)
  • ⅔ Cup Brown Sugar (130g)
  • ½ tsp Ground Nutmeg
  • 1 and ½ tsp Cinnamon
  • ⅓ Cup Maple Syrup (113g)
Metric - US Conventional

Instructions

  • Preheat the oven 160°C (325°F) and line a baking tray with baking paper.
  • Spread the walnuts out over the baking tray and place in the oven for 10-15 minutes to roast them. They should be lightly golden.
  • Remove from the oven and set aside to cool.
  • Grease and line a 9"x13" baking pan and set aside.

Base;

  • Prepare the base by mixing the melted butter, maple syrup, milk, vanilla extract, eggs, caster sugar and brown sugar in a bowl until thick and combined.
  • Add in the self-raising flour and cinnamon and mix. Pour into the prepared dish and set aside.

Topping;

  • Combine the roasted walnuts, oats, flour, cinnamon, nutmeg and brown sugar in a separate bowl and mix together. Set aside.

Filling;

  • Peel, core and dice the apple into small chunks or thin slices. Which ever you prefer. (I do a mixture of both).
  • Place in a bowl with the maple syrup, cinnamon and mixed spice and mix.
  • Spread in an even layer over the base, pressing some of the apple slices into the base.
  • Top with the crumble and finally pour over the remaining maple syrup and place in the oven for 45-55 minutes. The top and sides will be golden and it will be firm. A skewer inserted in the center should come out clean.
  • Allow to cool before slicing and serving.
  • Best kept in the fridge for up to a week as the apples will go soggy in the heat.

Notes

Use pure maple syrup like this one and pure vanilla extract like this one.
9x13 pan.
