Key Ingredient Notes

Ingredients for apple cinnamon oat muffins displayed in small bowls on a marble counter top.
  • Maple syrup: Any liquid sweetener should work (honey is the best swap), but I prefer the flavor of maple syrup.
  • Rolled oats: I like the texture of large flake rolled oats, but you can use quick oats in a pinch. I do not recommend swapping for instant oats or steel cut oats.
  • Apples: I use honeycrisp, but braeburn, fuji, cortland, empire, golden delicious, and granny smith work too. Here’s more information to help you choose the right apples for baking.

Top Tips for Moist and Delicious Muffins

Whole wheat flour has a tendency to get tough and dry if not handled properly. Here’s what I learned after thoroughly testing this recipe for perfectly moist and light muffins:

  1. Don’t over-mix your batter. Over-working your batter will make your muffins tough and dry. Stir until just combined and stop there.
  2. Don’t bake for too long. Watch your muffins and remove them from the oven as soon as they’re ready. You’ll know they’re done when a toothpick inserted into the center comes out mostly clean with a few moist crumbs, and the tops look set. Remove them from the pan after 5-minutes of cooling, or they’ll continue cooking and dry out.

Common Questions

How do I store apple cinnamon oat muffins?

Let your muffins cool to room temperature before storing. Store in a sealed bag or airtight food container for up to three days on the counter. To keep them fresh longer, store in the freezer for up to three months and defrost on the counter overnight before eating.

Can I store these muffins in the fridge?

You can, but I don’t recommend it. They get more dry and a bit tough in the fridge, so it’s best to freeze them or keep at room temperature. If you have to refrigerate them, gently microwave for 10-15 seconds before eating.

Healthy Apple Cinnamon Oat Muffins

Yield: 12 muffins
Prep Time: 10 minutes
Cook Time: 20 minutes
Total Time: 30 minutes
Healthy muffins for fall! Naturally sweetened and made with 100% whole grains, these tasty apple cinnamon oat muffins are an easy, high-fiber snack your family will love.

Ingredients
 

  • 1 ½ cup whole wheat flour, spooned and levelled
  • ¾ cup rolled oats
  • 1 tsp baking powder
  • 1/2 tsp baking soda
  • 1 tsp salt
  • 2 tsp cinnamon
  • 6 Tbsp unsalted butter, melted and cooled to room temperature
  • ½ cup maple syrup
  • ½ cup unsweetened apple sauce
  • ½ cup plain Greek yogurt
  • 2 tsp vanilla extract
  • 2 large eggs
  • 1 cup finely chopped apple, about one small apple with skin on

Equipment

Instructions
 

  • Position oven rack to the middle and pre-heat to 350 F. Line a 12-cup muffin pan with paper or silicone liners. Set aside.
  • To a large bowl, add flour, oats, baking powder, baking soda, salt, and cinnamon. Whisk and set aside.
  • To a separate large bowl, add melted butter, maple syrup, apple sauce, Greek yogurt, vanilla, and eggs. Whisk until smooth.
  • Add dry ingredients and chopped apples to wet ingredients. With a large wooden spoon or spatula, mix until just combined. Be careful not to over-mix.
  • Scoop batter into muffin liners, distributing evenly. I like to use a 3-Tbsp cookie scoop for this step to minimize mess.
  • Transfer to the oven and bake for 18-22 minutes, or until tops are set and a toothpick placed in the center comes out mostly clean. Be careful not to over-bake these or they could dry out.
  • Let muffins cool in the pan for 5-minutes before transferring to a wire rack. Cool to room temperature before eating.

Notes

  • You can swap rolled oats for quick oats if needed.
  • I use low-fat Greek yogurt, but whole milk works too.
  • Honeycrisp apples are my favorite, but braeburn, fuji, cortland, empire, golden delicious, and granny smith will also work. Keep the skin on for extra fiber.
  • To avoid dry and tough muffins, don’t over-mix your batter and be careful not to over-bake. Whole wheat flour is a little sensitive, so be gentle!
