Ingredients  

  • 1.5 cups leftover cooked oatmeal
  • 2 cups flour
  • ¼ tsp salt
  • ½ tsp cinnamon
  • 1/8 tsp nutmeg
  • 1 tsp baking soda
  • 1 tsp vanilla
  • ½ cup coconut oil
  • 1/3 cup brown sugar
  • ¼ cup maple syrup
  • 2 eggs
  • 2 tbsp milk, optional if dry
  • ½ cup chocolate chips

Instructions 

  1. Preheat oven to 350. Mix dry ingredients (leftover oatmeal, flour, baking soda, cinnamon, salt, nutmeg) in large bowl and let sit.
  2. Mix vanilla, melted coconut oil, brown sugar, maple syrup in another bowl. Add in eggs and mix gently to incorporate them.
  3. Add dry ingredients to wet ingredients and mix until fully dissolved. You may need to add 1-2 Tbsp of milk if it seems too dry. Add in optional chocolate chips. Don’t overmix or your cookies will not be as soft and fluffy.
  4. Using a cookie scooper, scoop cookies onto greased baking pan or one lined with parchment paper.
  5. Bake for 11-14 minutes, or until cookies start to brown.
  6. Allow cookies to cool at least 5-10 minutes on a cooling rack.

Notes

I prefer to use half maple syrup (liquid) and half brown sugar. You could just do ½ cup of either, but I’ve always baked this way and I like the resulting texture and sweetness.
These leftover oatmeal cookies aren’t sugar free, but you can certainly reduce the sugar. You could use half the amount of sweetener and include one ripe mashed banana in the batter.
