Ingredients Method Notes

Ingredients
  

  • Wet Ingredients
  • 1½ cups milk (any type)
  • 2 large eggs
  • ½ cup maple syrup or honey
  • ½ cup unsweetened applesauce
  • ½ tsp vanilla extract
  • Dry Ingredients
  • 3 cups old-fashioned rolled oats
  • 1 tsp baking powder
  • 1½ tsp cinnamon
  • ¼ tsp nutmeg
  • ¼ tsp salt
  • Add-Ins
  • 1 heaping cup chopped, peeled apples
  • Optional: ½ cup chopped nuts
  • Optional: coarse sugar for topping

Method
 

  1. Before You Begin
  2. Prepare your cookware as needed. Cooking times and results may vary depending on your equipment and ingredients.
  3. Preheat oven to 350°F (177°C). Generously grease a 12-cup muffin pan.
  4. In a mixing bowl, whisk milk, eggs, syrup, applesauce, and vanilla until fully blended.
  5. Add oats, baking powder, cinnamon, nutmeg, and salt. Stir until evenly combined.
  6. Fold in chopped apples and optional nuts.
  7. Divide mixture evenly into muffin cups, ensuring each portion contains both liquid and oats.
  8. Bake 28–30 minutes, or until tops look set and lightly golden.
  9. Visual cue: centers should feel firm and no longer wet.
  10. Allow to cool 5–10 minutes before removing from pan.

Notes

  • Batter may look loose before baking — this is normal and helps create a moist texture.
  • Stir mixture between scoops so apples are evenly distributed.
  • Use firm apples for better structure and balanced sweetness.
  • Bake until centers are fully set and no wet batter remains.
  • Cool slightly before serving to allow structure to firm up.
  • Refrigerate leftovers within 2 hours and store sealed up to 1 week or freeze up to 3 months.
  • Reheat until warmed through before serving.
