Ingredients

To make this delightful Apple Walnut Oat Crumble, you will need:

• 1 1/2 cups (150 g) rolled oats
• 1 cup (90 g) walnuts, chopped
• 2 medium apples, peeled, cored, and chopped
• 1/4 cup (60 ml) water
• 1/4 teaspoon ground cinnamon
• 1 teaspoon maple syrup (add more if you like it sweeter)
• 1/4 cup (60 ml) coconut oil or melted butter
• 1 tablespoon cocoa powder (optional)

Steps to Prepare

Step 1: Prepare the Apple Mixture

1. Start by preheating your oven to 350°F (175°C).
2. In a mixing bowl, combine the chopped apples, water, cinnamon, and maple syrup. Stir until the apples are evenly coated with the syrup and cinnamon.
3. Set this apple mixture aside to allow the flavors to meld together while you prepare the crumble topping.

Step 2: Make the Oat and Walnut Topping

1. In a separate bowl, mix the rolled oats, chopped walnuts, and cocoa powder (if using). The cocoa powder adds a subtle chocolatey depth to the crumble.
2. Melt the coconut oil or butter until liquid (if it’s not already), then pour it over the oat mixture. Stir well until the oats and walnuts are thoroughly coated, creating a crumbly texture.

Step 3: Assemble the Crumble

1. In a baking dish (about 8×8 inches or similar), spread the apple mixture evenly along the bottom.
2. Sprinkle the oat and walnut mixture on top of the apples, ensuring the topping covers the apples fully and evenly.

Step 4: Bake the Crumble

1. Place the baking dish in the preheated oven and bake for about 25-30 minutes, or until the top is golden brown and the apples are tender.
2. If you prefer a softer apple texture, bake for an additional 5-10 minutes. You should see bubbling around the edges when it’s ready.
3. Remove from the oven and allow it to cool for a few minutes before serving.

Step 5: Serve

Serve the Apple Walnut Oat Crumble warm. It’s delicious on its own but also pairs beautifully with a dollop of Greek yogurt, whipped cream, or a scoop of vanilla ice cream.

FAQs

Q: Can I use instant oats instead of rolled oats?
A: Rolled oats are best for this recipe because they create a heartier texture, but you can use instant oats if that’s what you have. Keep in mind that the crumble may be slightly softer.

Q: Can I make this crumble vegan?
A: Yes! Use coconut oil instead of butter to keep it vegan-friendly.

Q: How can I make this recipe gluten-free?
A: This recipe can easily be made gluten-free by using certified gluten-free oats.

Q: Can I substitute the walnuts with other nuts?
A: Absolutely. Pecans, almonds, or even hazelnuts would work well in place of walnuts for a different flavor profile.

Q: Can I add more sweetener?
A: Yes, feel free to adjust the amount of maple syrup according to your taste. You can also drizzle additional maple syrup on top after baking for an extra touch of sweetness.

Tips for Making the Perfect Apple Walnut Oat Crumble

• Use Fresh, Firm Apples: For the best texture, choose apples that are firm and slightly tart, like Granny Smith or Honeycrisp. Softer varieties might turn mushy during baking.
• Control the Sweetness: Maple syrup provides a natural sweetness, but feel free to add a little brown sugar if you prefer a sweeter crumble.
• Spice it Up: While cinnamon adds warmth, you could experiment with a pinch of nutmeg, cardamom, or cloves for a deeper, spicier flavor.
• Consider the Cocoa Powder Optional: The cocoa powder is optional and adds a subtle, earthy flavor that pairs well with the walnuts. If you’re a chocolate fan, try it! Otherwise, you can skip it and enjoy a more traditional flavor.
• Try Coconut Oil for Flavor: Coconut oil complements the apple and walnut flavors beautifully, adding a mild, tropical note. However, if you prefer a buttery flavor, feel free to use melted butter instead.

Storage Tips

• In the Refrigerator: Store any leftover crumble in an airtight container in the refrigerator for up to 3-4 days. When you’re ready to enjoy it again, warm it up in the microwave or oven to bring back its cozy texture.
• In the Freezer: This crumble can be frozen! Place it in an airtight container and freeze for up to 1 month. Thaw in the refrigerator overnight and reheat in the oven at 350°F (175°C) for about 10-15 minutes until warmed through.
• Reheating Tips: When reheating, you can add a sprinkle of extra oats on top to refresh the crumble’s texture.
