Why You’ll Love This Recipe

These muffins aren’t just delicious—they’re also packed with ingredients you can feel good about. The oats and flaxseed provide fiber, the grated apples add natural sweetness and moisture, and the hint of cinnamon ties everything together with warm, comforting notes. Plus, the crumbly streusel topping adds just the right amount of sweetness and crunch.

Best Apples for Muffins

When it comes to baking apple muffins, not all apples are created equal. The best apples for this recipe are those that strike a balance between sweetness and tartness, and that hold their shape and flavor when baked. Since the apples are grated, you don’t need to worry as much about texture—what matters most is the flavor and moisture they bring to the batter. Here are a few great choices:

Honeycrisp – Sweet, juicy, and slightly tart, Honeycrisp apples are a top pick. They add a bright, fresh flavor that complements the cinnamon and oats beautifully.
Granny Smith – If you like a bit more tang in your muffins, Granny Smiths are your go-to. Their tartness balances the sweetness of the streusel and honey, creating a more complex flavor.
Fuji – These apples are super sweet and very juicy. They’re great if you want extra moisture and a naturally sweet muffin.
Braeburn – With a mix of sweet and tart flavors, Braeburn apples offer a nice depth and bake down nicely without becoming mushy.
Pink Lady – Crisp and slightly tart with floral notes, these apples are ideal for baking and add a subtle brightness to each bite.

If you’re using extra apples you already have on hand, feel free to mix varieties for a more layered flavor profile. Just remember to taste your apples before grating—you want them to be flavorful and fresh.

Ingredients for Healthy Apple Muffins

1 cup all-purpose flour
2/3 cup old-fashioned oats, ground into a flour in the food processor or blender
1 tsp flaxseed, ground
1/2 cup coconut sugar (or any regular sugar)
1 1/4 tsp baking powder
1/2 tsp baking soda
1 tsp ground cinnamon
1/4 tsp salt
1/2 cup milk, you can also use almond milk, coconut milk, or oat milk
2 tbsp coconut oil, melted – you could also use avocado oil or vegetable oil
1 large egg
2 tbsp honey
1/2 tsp vanilla extract
1 1/3 cups grated fresh apples – grating the apples works best but you could also use finely chopped apple

Ingredients for the Streusel Topping

1/2 cup unbleached all-purpose flour
1/4 cup light or dark brown sugar, packed
1/4 cup rolled oats (old-fashioned or quick-cooking)
1/8 tsp salt
1/4 teaspoon of ground cinnamon
4 tbsp butter, at firm room temperature

Step-by-Step Instructions

Preheat Your Oven – Set your oven to 400°F and line a 12-cup muffin tin with paper muffin liners or lightly coat with cooking spray.
Mix the Dry Ingredients – In a large bowl or the bowl of a stand mixer, combine the flour, ground oats, flaxseed, coconut sugar, baking powder, baking soda, cinnamon, and salt. Stir everything together with a whisk to ensure it’s evenly distributed.
Prepare the Wet Ingredients – In a smaller mixing bowl, whisk together the milk, melted coconut oil, egg, honey, and grated apples until well blended.
Combine Wet and Dry – Gradually pour the wet ingredients into the bowl with the dry ingredients, stirring gently until just combined. Be careful not to overmix—a few lumps are perfectly fine.
Fill the Muffin Cups – Spoon the muffin batter evenly into the prepared muffin pan, filling each about three-quarters full.
Make the Streusel Topping – In a separate bowl, whisk together the flour, brown sugar, oats, and salt. Using a fork or pastry cutter, work the butter into the mixture until it forms coarse crumbs. Sprinkle the streusel evenly over the top of each muffin.
Bake and Cool – Place the muffin tin in the oven and bake for 5 minutes, THEN TURN THE HEAT DOWN to 350 degrees F for about 15 minutes or until the tops are golden and a toothpick inserted into the center comes out clean. Remove the muffins from the tin immediately and cool on a wire rack.

Tips for Success

Grating the Apples: Use a box grater to shred your apples finely, as this ensures they blend seamlessly into the batter and keep the muffins moist. You could also use a food processor with a grater to accomplish this.
Customize It: Feel free to add chopped nuts, dried cranberries, raisins or even a handful of chocolate chips for extra texture and flavor. The crumb topping is optional but makes these muffins extra special!
Storage: These muffins store well in an airtight container at room temperature for up to 2 days or in the fridge for up to a week. You can also freeze them for longer storage—just thaw and reheat before enjoying.
