Ingredients
Scale
- 2 cups old-fashioned rolled oats (use certified gluten-free if needed)
- 2 tablespoons poppy seeds
- 1 teaspoon baking powder
- ½ teaspoon salt
- 2 large eggs
- 1¾ cups milk (any kind)
- ⅓ cup honey or maple syrup (or ¼ cup sugar)
- 3 tablespoons melted butter or coconut oil
- Zest of 2 lemons (about 2 tablespoons)
- ¼ cup fresh lemon juice (about 2 lemons)
- 1 teaspoon vanilla extract
- Optional: ½ teaspoon lemon extract for extra lemon flavor
- Optional: 2-3 tablespoons sugar for topping
Instructions
- Preheat Your Oven: Set your oven to 350°F (175°C). Generously grease a 9×9-inch baking dish with butter or cooking spray, or line it with parchment paper leaving overhang on two sides for easy removal.
- Mix Dry Ingredients: In a large mixing bowl, combine the rolled oats, poppy seeds, baking powder, and salt. Stir together until the poppy seeds are evenly distributed throughout the oats.
- Prepare Wet Ingredients: In a medium bowl, whisk together the eggs, milk, honey (or maple syrup), melted butter, lemon zest, lemon juice, vanilla extract, and lemon extract if using. Whisk vigorously until everything is well combined and the mixture is smooth. The lemon juice may cause slight curdling with the milk—this is completely normal and won’t affect the final result.
- Combine Wet and Dry: Pour the wet ingredients into the bowl with the dry ingredients. Stir everything together with a spatula or wooden spoon until the oats are completely coated and the mixture is evenly combined. Let the mixture rest for 5 minutes—this allows the oats to absorb some of the liquid and ensures even baking.
- Transfer to Baking Dish: Pour the oatmeal mixture into your prepared baking dish and spread it out evenly with a spatula. Gently tap the dish on the counter a few times to release any air bubbles and settle the mixture. If you want a slightly sweet, crispy top, sprinkle 2-3 tablespoons of sugar evenly over the surface.
- Bake: Place the baking dish in the preheated oven and bake for 30-35 minutes, until the top is golden brown and the center is set. A toothpick inserted in the center should come out mostly clean with just a few moist crumbs. The edges should pull away slightly from the sides of the pan. The oatmeal will continue to firm up as it cools, so don’t worry if the center seems slightly soft.
- Cool and Serve: Remove from the oven and let cool for at least 10-15 minutes before slicing. This cooling time is crucial for allowing the structure to set properly. Cut into squares and serve warm or at room temperature. This is delicious topped with Greek yogurt, fresh berries, a drizzle of honey, or even a simple dusting of powdered sugar with extra lemon zest.
Notes
- Lemon Intensity: For more pronounced lemon flavor, increase the lemon zest to 3 tablespoons and add ½ teaspoon lemon extract.
- Sweetness Level: Adjust the honey or sugar to taste. This recipe is moderately sweet—increase by 2-3 tablespoons for a sweeter version.
- Make It Vegan: Use plant-based milk, replace eggs with flax eggs, use maple syrup instead of honey, and substitute coconut oil for butter.
- Texture Preference: For creamier oatmeal, add an extra ¼ cup milk. For firmer squares, reduce milk by ¼ cup.
- Fresh Lemon is Key: Never substitute bottled lemon juice—fresh lemons make all the difference in flavor.
