Easy oat flour apple pie muffins with streusel

Instead of butter, I swapped in Greek yogurt for extra moisture and protein, and the oat flour gives the muffins a heartier texture. The fresh apple chunks and cinnamon taste like Fall but without any refined sugar!
The streusel is the real star here—crumbly, sweet, and the perfect topping. It adds just the right amount of crunch to balance the softness of the muffin, making them feel special but still easy enough to make any time.

Ingredients you'll need
These healthy apple pie muffins are made with simple, wholesome ingredients like oat flour, fresh apples, and Greek yogurt. Naturally sweetened with maple syrup, they’re gluten-free and full of cozy fall flavors. Here’s a list of everything you need to get started:
- Oat flour – A wholesome, gluten-free option that adds a light, fluffy texture to the muffins.
- Baking powder & baking soda – These work together to give the muffins a nice rise.
- Salt – Enhances the flavors in the muffins.
- Apple pie spice (or cinnamon) – For that warm, cozy apple pie flavor. If you don’t have apple pie spice, cinnamon works perfectly!
- Granny Smith apples – Their tartness balances the sweetness, and they hold up well when baked.
- Coconut oil – A healthy fat that keeps the muffins moist. Melted butter works, too, if you don’t have coconut oil.
- Maple syrup – A natural sweetener that adds a rich, caramel-like flavor.
- Eggs – Help bind the ingredients and add structure to the muffins.
- Greek yogurt – Adds protein and moisture, making the muffins extra soft. Use plain or vanilla for best results.
- Coconut sugar (for the crumble) – A healthier alternative to refined sugar, adding a hint of caramel flavor.
How to make healthy apple crumble muffins
These healthy apple crumble muffins are moist, flavorful, and easy to make. Follow these step-by-step instructions (with pictures for reference) so anyone can bake them, no matter their skill level. You’ll find the full recipe and measurements in the recipe card at the bottom of the page.
First, preheat your oven to 425°F and line a 12-cup muffin tin with liners.
In a large bowl, whisk together the oat flour, baking powder, baking soda, salt, and apple pie spice. Toss the grated and diced apples in 1 tablespoon of flour to coat, then mix them into the dry ingredients.
Whisk together the melted coconut oil, maple syrup, eggs, and Greek yogurt in a separate bowl. Pour the wet mixture into the dry ingredients and stir until everything is well combined.
Next, make the crumble topping by mixing the coconut sugar, oat flour, melted coconut oil, and cinnamon until it becomes crumbly.
Fill each muffin cup about two-thirds full with batter, then sprinkle the crumble topping evenly over each one.
Bake at 425°F for 5 minutes, then lower the temperature to 375°F and bake for another 12-15 minutes, or until a toothpick comes out clean.
Enjoy your healthy apple crumble muffins!
Expert baking tips
- Making Ingredient Substitutions: If you make a substitution, please check the list below before doing it. Baking is very scientific, and not all substitutions work perfectly.
- Measure Ingredients Accurately: Use a kitchen scale or proper measuring cups to ensure accurate measurements. Spoon and level the flour instead of packing it down to avoid dense muffins.
- Room Temperature Ingredients: For best results, use room temperature eggs and Greek yogurt. This helps create a smoother batter and leads to better rising.
- Don’t Overmix the Batter: Gently fold the wet and dry ingredients together until just combined. Overmixing can lead to tough muffins.
- Coat Apples in Flour: Toss the grated and diced apples in a bit of oat flour before adding them to the batter. This prevents them from sinking to the bottom of the muffins during baking.
- Use Fresh Apples: Fresh, firm apples provide the best flavor and texture. Avoid using mushy or overripe apples for this recipe.
Easy ingredient substitutions:
- Oat flour: You can use all-purpose flour or almond flour if you’re not looking for a gluten-free option. Just keep in mind that the texture may vary slightly.
- Coconut oil: Melted butter or vegetable oil can be used instead, though the flavor will change slightly.
- Maple syrup: Honey or agave syrup works well as a substitute for natural sweetness.
- Greek yogurt: You can replace it with regular yogurt, sour cream, or even applesauce for a dairy-free option.
- Granny Smith apples: Any firm apple, like Honeycrisp or Fuji, will work, but adjust the sweetness if needed.
- Coconut sugar: Brown sugar or regular granulated sugar can be used instead, but coconut sugar has a lower glycemic index.
- Eggs: For an egg substitute, try using flaxseed meal (1 tablespoon of flaxseed meal mixed with 2.5 tablespoons of water = 1 egg) or unsweetened applesauce (¼ cup per egg).
