2 tsp ground cinnamon Adds warm spice; increase to 2½ tsp for extra punch.

½ cup milk (dairy or plant) Keeps oats moist; almond milk adds subtle nuttiness.

1 large egg Binds the mixture; can replace with flax egg for vegans.

½ tsp vanilla extract Enhances sweet notes; optional but recommended.

¼ tsp salt Balances sweetness; a pinch of sea salt adds depth.

Optional: ½ cup diced apples or raisins Adds natural sweetness and texture.

Step‑by‑Step Instructions

Preheat & Prepare Pan

Preheat the oven to 375°F (190°C). Lightly grease a 9‑inch square baking dish or line with parchment for easy release.

Pro Tip: If you like a crisp top, place the dish on the middle rack and finish with a 2‑minute broil.

Mix Dry Ingredients

In a large bowl combine oats, brown sugar, cinnamon, and salt. Stir until evenly coated; the sugar will cling to the oats.

Pro Tip: Toast the dry mixture for 3 minutes before adding wet ingredients for extra nuttiness.

Combine Wet Ingredients

Whisk milk, egg, and vanilla together. Pour over the oat mixture, stirring gently until just combined. Fold in optional apples or raisins now.

Pro Tip: Do not over‑mix; a few dry spots are fine and will hydrate during baking.

Bake to Golden Perfection

Transfer the batter to the prepared pan, spreading evenly. Bake for 20‑25 minutes, until the top is deep golden and a toothpick inserted near the center comes out clean.

Pro Tip: Rotate the pan halfway through baking for uniform browning.

Serve Warm or Store

Let the baked oats cool 5 minutes, then cut into squares. Serve warm with a drizzle of milk or yogurt. Refrigerate leftovers in an airtight container for up to 4 days.

Pro Tip: Reheat individual portions in the microwave for 30‑40 seconds.

Expert Tips

Tip #1: Use Old‑Fashioned Oats

They retain shape better than instant oats, giving a satisfying bite after baking.

Tip #2: Add a Crunch Topping

Scatter a tablespoon of chopped pecans or oat streusel before baking for extra texture.

Tip #3: Sweeten with Fruit

Fold in mashed banana or unsweetened applesauce to reduce added sugar while staying moist.

Tip #4: Portion for Freezing

Cool completely, then wrap individual squares in foil. Freeze up to 2 months; reheat directly from frozen.

Frequently Asked Questions

Replace the egg with a flax “egg” (1 Tbsp ground flax + 3 Tbsp water) and use plant‑based milk. The texture remains creamy.
