Easy Healthy Raspberry Oatmeal Crumble (High-Fiber Dessert)

For a fruit-forward, high-fiber dessert, this crumble is a “Gold Standard” choice. It swaps refined white flour and heavy sugars for nutrient-dense rolled oats and natural sweeteners. From an expertise perspective, the secret to a professional-grade healthy crumble is the “clumping technique” for the topping and using chia seeds for the filling. The chia seeds naturally thicken the fruit juices without the need for cornstarch, while the coconut oil binds the oats into crispy clusters rather than a fine dust.

Ingredients:

The Berry Foundation

• 3 cups Fresh or Frozen Raspberries (Tart & antioxidant-rich)
• 1 tbsp Chia Seeds (The professional thickening secret)
• 1 tbsp Maple Syrup

The “Gold Standard” Crumble Topping

• 1 cup Rolled Oats (Old-fashioned for texture)
• 1/2 cup Almond Flour (Nutty flavor)
• 2 tbsp Coconut Oil, melted
• 1 tbsp Maple Syrup or Raw Honey
• 1 tsp Ground Cinnamon
• A pinch of Sea Salt

The Finishing Touch

• 1/2 cup Plain Greek Yogurt (Protein pairing)
• Optional: Sprig of fresh mint

Preparation Steps:

1. The Professional “Fruit Prep”

1. Preheat oven to 375°F (190°C). In a medium baking dish, toss raspberries with 1 tbsp maple syrup and chia seeds.
2. Technique: Let berries sit for 5 minutes while preparing the topping. The chia seeds will absorb excess juice, ensuring a thick fruit layer rather than a watery mess.

2. The Crumble Fusion

3. In a separate bowl, combine oats, almond flour, cinnamon, and salt. Drizzle with melted coconut oil and syrup.
4. Use a fork to mix until oats are well-coated and form small clumps. This uniformity is necessary for even browning.

3. The Even Layering

5. Scatter the crumble mixture evenly over the raspberries.
6. Crucial Step: Do not pack the topping down. Keeping it loose allows hot air to circulate, creating a crispy, professional texture.

4. The Golden Bake

7. Bake for 20–25 minutes until fruit is bubbling and oats are deep golden-brown.
8. Allow dish to rest for 10 minutes. This allows the chia-fruit filling to set into a jam-like consistency.

Expert Tips:

• Frozen Fruit Rule: If using frozen berries, do not thaw them beforehand. Toss them with the chia seeds while frozen and increase the bake time by 5 minutes.
• Thickener Swap: The chia seeds are the professional replacement for cornstarch. They provide Omega-3s and prevent the filling from becoming gluey.
