Combine oats, chia seeds, and half the chopped hazelnuts in a bowl until integrated.
- 2
Add cocoa powder and milk, stirring until the mixture is homogeneous.

Cover and refrigerate overnight or at least 4 hours to allow chia to hydrate and oats to soften into a creamy consistency.
- 4
When ready to eat, melt dark chocolate in the microwave in 30-second intervals to prevent burning.
- 5
Add remaining hazelnuts and pour the melted chocolate over the oat mixture.

The chocolate will solidify immediately when it contacts the cold mixture, creating a crispy layer.
Tips
Melt chocolate in short intervals to prevent scorching and maintain smooth texture.
Good to Know
Refrigerate in covered container up to 3 days. Add chocolate topping just before serving.
Prepare oat mixture through step 3 and refrigerate overnight. Melt chocolate and add topping when ready to eat.
Serve cold, immediately after chocolate topping solidifies for maximum crispness.
Common Mistakes
Do not microwave chocolate in long intervals to avoid burnt, grainy texture.
Do not skip the chill time to avoid mushy, unsoaked oats.
