Ingredients

Wet Ingredients

  • ½ cup honey
  • ½ cup natural peanut butter (fresh and runny)
  • 2 tsp vanilla extract
  • 1 ¾ cups 2% milk

Dry Ingredients

  • 2 cups old fashioned oats
  • ¼ cup ground flaxseed
  • 1 tsp baking powder
  • ½ tsp salt
  • ½ tsp cinnamon
  • ⅓ cup mini semi-sweet chocolate chips, plus 1-2 tablespoons extra for topping

Instructions

  1. Preheat and Prepare Pan: Position the oven rack in the middle and preheat the oven to 350°F (175°C). Line a baking pan with parchment paper to prevent sticking, and set it aside for later use.
  2. Combine Ingredients: In a large mixing bowl, add the honey, natural peanut butter, vanilla extract, oats, ground flaxseed, baking powder, salt, cinnamon, mini chocolate chips, and milk. Stir everything together until all the ingredients are thoroughly combined and form a consistent batter.
  3. Pour Batter into Pan: Transfer the oat mixture into your prepared baking pan. Use a spatula to flatten the batter evenly and spread it to the edges of the pan. Sprinkle an additional 1-2 tablespoons of mini chocolate chips evenly over the top for extra chocolate bursts.
  4. Bake: Place the pan in the preheated oven and bake for 28 to 35 minutes. The baked oatmeal should turn golden brown and be set—meaning it won’t jiggle when you gently shake the pan.
  5. Cool and Serve: Remove the pan from the oven and allow the baked oatmeal to rest for at least 15 minutes. This resting period helps the oatmeal firm up, making it easier to slice and serve. Enjoy warm or at room temperature.

Notes

  • Peanut butter: Use a natural peanut butter with only peanuts in the ingredients. You can substitute almond butter or any other nut or seed butter if preferred.
  • Oats: Old fashioned rolled oats offer the best texture. Quick oats can be used but may yield a softer consistency, while steel-cut oats are not recommended.
  • Chocolate chips: Mini semi-sweet chocolate chips distribute better throughout the oatmeal, but regular size can work as well. For a lower sugar option, use sugar-free or low sugar chocolate chips.
  • Milk: Though 2% cow’s milk is used in this recipe, unsweetened non-dairy milk (such as almond or oat milk) can be substituted if desired.
  • Rest time: Allow the baked oatmeal to cool for at least 15 minutes before slicing to ensure it holds together and does not crumble.
