Ingredients

Scale

Dry Ingredients

  • 2 cups old-fashioned rolled oats
  • ⅓ cup light brown sugar (packed)
  • 1 tsp baking powder
  • ¼ tsp salt
  • 1 tbsp lemon zest

Wet Ingredients

  • 1⅓ cups milk (whole, coconut, almond, or oat)
  • 1 large egg (room temperature)
  • ¼ cup lemon juice (freshly squeezed)
  • ½ tsp vanilla extract
  • ¼ tsp almond extract
  • 2 tbsp unsalted butter (melted)

Add-ins

  • 1 cup blueberries (fresh or frozen)
  • ½ cup almonds (chopped)

For Serving

  • Maple syrup
  • Yogurt
  • Nut butter
  • Fresh berries

Instructions

  1. Preheat: Preheat the oven to 375° F. Grease an 8×8-inch baking dish with cooking spray and set it aside to prepare for baking.
  2. Whisk Wet Ingredients: In a medium-sized bowl, whisk together the milk, egg, lemon juice, vanilla extract, and almond extract until fully combined and smooth.
  3. Mix Dry Ingredients: In a large bowl, combine the rolled oats, baking powder, salt, brown sugar, and lemon zest, thoroughly mixing to distribute the ingredients evenly.
  4. Combine Mixtures: Pour the milk and egg mixture along with the melted butter into the oat mixture. Stir well until all ingredients are evenly incorporated.
  5. Add Blueberries and Almonds: Gently fold in the blueberries and chopped almonds, being careful not to crush the berries or overmix.
  6. Bake: Pour the entire mixture into the prepared baking dish. Bake in the oven for 35 to 40 minutes until the top is golden brown and the oatmeal is set in the center.
  7. Serve: Allow the oatmeal to cool slightly before serving. Enjoy warm or cold with optional toppings like maple syrup, yogurt, nut butter, or fresh berries.

Notes

  • You can substitute the milk with your preferred milk alternative such as almond, oat, or coconut milk.
  • Fresh or frozen blueberries both work well; if using frozen, do not thaw before adding.
  • For a nut-free version, omit almonds or substitute with seeds like pumpkin or sunflower seeds.
  • Leftovers can be refrigerated for up to 4 days and reheated in the microwave.
  • Adjust sweetness by increasing or decreasing the brown sugar according to taste.
  • To make it vegan, substitute the egg with a flax egg and use a plant-based butter.
