Ingredients Overview

Let’s break down the main components of this healthy apple crumble and how they contribute to flavor, texture, and nutrition.

For the Apple Filling:

1. Apples (2–3 medium)

Choose firm, tart-sweet apples like Granny Smith, Honeycrisp, or Pink Lady. They hold their shape during baking and balance the sweetness of the topping.

2. Cinnamon & Nutmeg

These classic warming spices elevate the natural sweetness of the apples and give that nostalgic autumn aroma.

3. Lemon Juice

Adds brightness and prevents the apples from browning. It also enhances flavor depth.

4. Maple Syrup or Low-Calorie Sweetener

Use 1–2 tablespoons of maple syrup or a sugar-free alternative like Stevia, Monk fruit, or Erythritol to lightly sweeten the filling.

For the Protein Crumble Topping:

1. Rolled Oats

Provide a hearty, chewy texture and fiber. Choose gluten-free oats if needed.

2. Vanilla or Cinnamon Protein Powder

Adds structure and boosts protein content. Whey, casein, or plant-based all work—just avoid overly sweetened ones.

3. Almond Flour or Oat Flour

Gives a crumbly texture without refined flour. Almond flour adds healthy fats and richness.

4. Coconut Oil or Greek Yogurt

Used sparingly to bind the topping and add moisture. Coconut oil creates a crispier finish, while Greek yogurt keeps it lower in fat and more protein-rich.

5. Cinnamon + Pinch of Salt

Essential for balancing sweetness and creating depth in the crumble layer.

Step-by-Step Instructions

This healthy crumble comes together in about 10 minutes of prep time and bakes in under 30.

1. Preheat Oven

Set your oven to 350°F (175°C) and lightly grease a small baking dish (8×8 or equivalent).

2. Prepare the Apple Filling

Peel (optional) and slice 2–3 apples thinly and toss in a mixing bowl with:

• 1 tbsp lemon juice

• 1–2 tbsp maple syrup or low-calorie sweetener

• ½ tsp cinnamon

• ⅛ tsp nutmeg (optional)

• 1 tsp cornstarch or arrowroot (for thickening)

Spread the apple mixture evenly in the baking dish.

3. Mix the Crumble Topping

In another bowl, combine:

• ½ cup rolled oats

• ¼ cup vanilla or cinnamon protein powder

• ¼ cup almond flour

• 1 tbsp coconut oil (or 2 tbsp Greek yogurt for lower fat)

• 1–2 tsp maple syrup or sweetener

• ½ tsp cinnamon

• Pinch of salt

• 1–2 tbsp almond milk (as needed to moisten)

Stir until a crumbly dough forms. It should clump when pinched but not be overly wet.

---

4. Assemble and Bake

Sprinkle the crumble evenly over the apples. Press down gently.

Bake at 350°F for 25–30 minutes, or until the topping is golden and the apples are bubbling.

Let cool slightly before serving.
