Blueberry Crumble with Oats

Preheat the oven to 180–185 °C top/bottom heat. Prepare a suitable baking dish (approx. 20 cm x 25 cm).

Place the oats in a large bowl. Melt the butter in a small saucepan over low heat (approx. 2–3 minutes) and then pour it over the oats. Add honey, vanilla extract, and cinnamon and mix everything well until a crumbly mixture forms.

Place the frozen blueberries directly into the baking dish, sprinkle with cornstarch, and mix gently. Distribute the prepared oat mixture evenly over the berries, ensuring they are completely covered.
