old fashioned oats. Hold their shape well during baking and create a chewy, satisfying texture. Avoid using steel-cut oats or quick oats.
milk. Whole milk gives the richest flavor but any milk, dairy or plant-based, will work. Almond, oat, and coconut milk are great non-dairy options.
honey. A natural sweetener that complements the berries and cinnamon. You can substitute with maple syrup or agave if preferred.
fresh blueberries. Fresh blueberries add natural sweetness, juiciness, and a pop of color. If using frozen, stir them in while still frozen to minimize color bleeding and sogginess.

Recipe Notes & Tips:

Use Fresh or Frozen Blueberries: Fresh blueberries hold their shape best. If using frozen, add them straight from the freezer to avoid excess bleeding or watery batter.
Grease the Pan Well: Use butter, oil, or parchment paper to prevent sticking and make cleanup easier.
Let It Cool Before Slicing: Allow the baked oatmeal to cool for at least 10 minutes before cutting. This helps it firm up and hold its shape.
Customize the Sweetness: Taste the batter before baking and adjust the honey to your preference, especially if your blueberries are very sweet or tart.
Make It Ahead: Mix the ingredients the night before, refrigerate the unbaked dish, and bake in the morning. You may need to add 5-10 minutes to the bake time.
