Prepare the Berry Compote: In a small saucepan over medium-low heat, combine frozen mixed berries, a splash of honey or maple syrup, and a dash of vanilla extract. Stir gently for 5-7 minutes until thickened.

Cook the Oats: In a separate medium saucepan, bring water to a boil. Add a pinch of salt, then stir in the old-fashioned oats. Reduce heat to medium-low, simmer for 5-8 minutes.

Whisk the Eggs: Crack large eggs into a bowl and whisk until fully blended for a smooth, custard-like texture.

Combine Mixtures: Once oats are cooked, stir in cold milk, then gradually add the whisked eggs over low heat for 60-90 seconds until thickened.

Serve and Enjoy: Spoon custard oats into bowls, top with berry compote, and personalize with additional toppings as desired.
