Custard Baked Oats

Description: A high-protein, fiber-rich breakfast that tastes like a warm vanilla custard cake. Unlike traditional mushy oatmeal, this version is firm enough to slice but soft enough to melt in your mouth.

Ingredients

Yields: 4–6 servings | Prep time: 5 mins | Bake time: 35–40 mins

  • 2 cups Old-fashioned rolled oats

  • 3 cups Milk (dairy, almond, or oat milk)

  • 3 Large eggs (The key to the “custard” texture)

  • 1/2 cup Plain Greek yogurt (adds tang and creaminess)

  • 1/3 cup Maple syrup or honey

  • 1 tbsp Vanilla extract

  • 1 tsp Baking powder

  • 1/2 tsp Sea salt

  • Optional: 1 tsp Cinnamon, 1/4 cup chopped nuts (walnuts/pecans), or 1 cup berries.

Step-by-Step Instructions

  1. Prep: Preheat your oven to 180°C (350°F). Lightly grease a 9×9 inch or 8×8 inch glass baking dish with butter or coconut oil.

  2. Mix (The “Custard” Method):

    • For a Cake Texture: Place all ingredients in a blender and pulse for 30 seconds until the oats are partially broken down.

    • For a Hearty Texture: Whisk the eggs, milk, yogurt, vanilla, and syrup in a bowl. Fold in the dry oats, salt, and baking powder.

  3. Assemble: Pour the mixture into the prepared baking dish. If using nuts or fruit, sprinkle them evenly over the top.

  4. Bake: Bake for 35–40 minutes. The oats are done when the center is firm to the touch and the edges are lightly golden brown.

  5. Set: Let it cool for at least 10 minutes before slicing. This allows the custard to fully set so you get those perfect squares shown in the photo.

Tips & Notes

  • Don’t Skip the Salt: A pinch of salt balances the sweetness and makes the vanilla flavor pop.

  • Resting Period: If you have time, let the unbaked mixture sit in the pan for 10 minutes before putting it in the oven. This helps the oats hydrate for a more uniform “custard” feel.

  • The “Jiggle” Test: When you pull it out of the oven, the center should have a very slight “jiggle” but not be liquid. It will firm up as it cools.

Benefits

  • Satiety: High protein from the eggs and Greek yogurt keeps you full until lunch.

  • Meal Prep Friendly: These squares stay fresh in the fridge for up to 5 days and reheat perfectly in the microwave.

  • Digestibility: Blending or soaking the oats makes them easier on the stomach than raw or quick oats.

Recipe Q&A

Q: Can I make this vegan? A: You can use flax eggs (3 tbsp ground flax + 9 tbsp water), but the texture will be more “dense” and less “custardy” than the egg version.

Q: Can I use Steel Cut oats? A: No. Steel-cut oats require much more liquid and a longer cook time; they will remain crunchy/hard in this specific recipe.

Q: Why did my oats turn out soggy? A: This usually happens if the oven wasn’t fully preheated or if the dish was pulled out too early. Ensure the center is set before removing.
