ingredients in bowls to make lemon blueberry baked oatmeal cups.

Ingredients

  • Milk– I like to use unsweetened vanilla almond milk, but you can use your favorite milk.
  • Pure maple syrup– to sweeten the oats.
  • Coconut oil– measure the coconut oil and then melt. Cool to room temperature before using.
  • Lemon zest– use a microplane to zest one lemon.
  • Lemon juice– use a lemon squeezer to juice the lemons.
  • Eggs– use large eggs.
  • Vanilla extract– always use pure vanilla extract, not imitation vanilla.
  • Oats– use old fashioned rolled oats, not quick oats. If you need the recipe to be gluten-free, make sure you use gluten-free oats.
  • Chia seeds– I like adding chia seeds for extra fiber and protein. Store chia seeds in the freezer so they don’t go rancid.
  • Baking powder– make sure it is fresh.
  • Salt– to enhance all of the flavors.
  • Blueberries– you can use fresh or frozen blueberries. If you are using frozen berries, do not thaw them!

How to Make Lemon Blueberry Baked Oatmeal Cups

  • Preheat oven to 350 degrees F. Generously grease a 12-cup muffin pan with nonstick cooking spray. Set aside. I don’t recommend using paper liners with oatmeal cups because they tend to stick to the paper.
  • In a large bowl, whisk together milk, maple syrup, oil, lemon zest, lemon juice, eggs, and vanilla.

  • Gently fold in the blueberries. You can use fresh or frozen blueberries. If you are using frozen berries, don’t thaw them, and stir them in gently so they don’t turn the mixture purple.

  • Spoon batter evenly into greased muffin cups, making sure each cup has an even amount of oats, liquid, and blueberries.

  • Bake for 25 to 30 minutes or until the edges are lightly browned and top appears set. Remove from the oven. Let cool in the pan for 5 to 10 minutes before serving.
  • The muffins are good served warm, at room temperature, or even cold.

Variations

  • Milk– you can use almond, cashew, soy, oat, or cow’s milk.
  • Oil or Butter– instead of coconut oil, you can avocado oil or your favorite oil. Melted butter will also work.
  • Flax Eggs– if you want the recipe to be vegan, you can use flax eggs instead of regular eggs. For one egg, combine 1 tablespoon of flaxseed meal and 3 tablespoons of water and allow to sit for about 5 minutes.
  • Honey– instead of pure maple syrup, you can sweeten the oats with honey.
  • Extract– add a little almond extract. If you want a stronger lemon flavor, add a little lemon extract.
  • Add-ins– feel free to add in hemp hearts or protein powder to amp up the nutritional value.

Toppings

The oatmeal cups are great plain, but if you want to add toppings, go for it. Here are some ideas!

  • Greek yogurt
  • Lemon zest
  • Fresh blueberries
  • Maple syrup
  • Whipped Cream
  • Nut butter or chopped nuts
  • Add a sweet lemon glaze!

How to Store & Freeze

  • How to Store: Let the muffins cool completely. Store in an airtight container in the refrigerator for up to 1 week.
  • How to Freeze: Let the muffins cool completely. Wrap the muffins individually with plastic wrap. Place in a freezer bag or freezer container. Freeze for up to 3 months. Thaw to room temperature or heat in the microwave.

    Made these last night & my kids took them to school this morning. They were the perfect carpool breakfast. Easy, and so good!

    I love the idea of these, and I do think they’re pretty good. For some reason I felt like they tasted too salty and I wonder if I should use kosher salt instead next time. I have 2 questions: Does anyone have tips for avoiding the scrambled-egg-type bottom I got? And maybe on a related note, how can I make these less fall-apart-y? Less oil, maybe?

    1. I use kosher salt. Did you bake them long enough? They should hold together. Don’t add less oil, that helps them hold together.
