A delicious and easy apple crumble muffin recipe
Muffins are like the Swiss army knife of baked goods. They serve so many purposes! Breakfast? Obviously. Snack? Absolutely. Dessert? Of course!
Muffins can be enjoyed all throughout the day, so it makes sense to keep a tasty batch stocked at all times. This apple crumble oatmeal muffin recipe is the one you need! These tasty treats-slash-totally-acceptable-breakfast-foods are so good. They’re topped with a mouth watering crumble and a sugar icing drizzle! What’s not to love?!
Ingredients in these apple crumble oatmeal muffins
These apple muffins come together with three sets of ingredients. We’ll start by preparing the muffin batter with ingredients like oats, flour, eggs, coconut sugar, and oil. Then, we’ll create the crumble mixture with flour, sugar, cinnamon, and oil, and the drizzle with a combination of powdered sugar and almond milk.
Muffins
- Flour: The base of the muffins begins with 2 cups of all purpose flour.
- Quick oats: Next, 1.5 cups of rolled oats will be used to thicken up the muffins.
- Baking powder: 1 tsp of baking powder will help the muffins rise properly.
- Baking soda: Follow the baking powder with 1/2 tsp of baking soda.
- Cinnamon: Next up, add flavor with 1 tsp of cinnamon.
- Salt: 1/4 tsp of salt makes a world of difference in baked goods, and these muffins are no different!
- Eggs: 2 eggs will help all of the dry ingredients bind together properly.
- Milk: Use 1 cup of milk for perfectly moist muffins. You can use regular whole milk, 2%, skim, or dairy-free options.
- Coconut sugar: Sweeten up the muffins with 1 cup of coconut sugar. If preferred, you can use brown sugar.
- Coconut oil: 1/2 cup of melted coconut oil will help prevent the muffins from drying out. (If needed, this can be substituted with melted butter.)
- Vanilla extract: Include 1 tsp of vanilla extract for flavor.
- Apples: Last but not least, add 1.5 cups of shredded apples! Grate them using a box grater for best results.
Crumble
- Flour: The crumble base is created with 2/3 cup of all purpose flour.
- Coconut sugar: From there, sweeten it up with 1/3 cup of coconut sugar.
- Cinnamon: Add flavor using 1 tsp of cinnamon.
- Coconut oil: Create a crumble that’s the perfect texture (not too dry) by adding 1/4 cup of coconut oil.
Drizzle
- Powdered sugar: 1 cup of powdered sugar creates a deliciously sweet icing.
- Almond milk: Pair it with 1-2 tbsp of almond milk for the perfect consistency.

How to maple apple crumble oatmeal muffins
This recipe yields 21 delicious muffins. These make a great dessert but also taste fabulous alongside a morning cup of coffee!
First, preheat the oven to 350°F and line a muffin tin with liners or nonstick spray. I use both and spray the inside of the muffin cups.
Then, grab a medium mixing bowl and combine the flour, oat, baking powder, baking soda, salt, and cinnamon. Set aside.
In a large mixing bowl, whisk the eggs and milk together. Beat in the sugar, and then add the coconut oil and vanilla extract. Mix until well combined.
Slowly add the flour mixture to the wet ingredients until everything is combined, and then fold in the shredded apples. Do not over-mix.
Scoop the muffin batter evenly into the tin. The batter should make about 21 muffins.
Stir the crumble ingredients in one bowl until a crumb texture forms, and then evenly sprinkle the crumb toppings over the top of the unbaked muffins.
Bake for 18-20 minutes, or until a toothpick inserted comes out clean.
Make the drizzle by whisking together the ingredients. Let the muffins cool for 20 minutes, and then drizzle with the icing.
Storing leftovers
Leftover apple oatmeal muffins should be stored in an airtight container. From there, they can be kept at room temperature or in the refrigerator for a longer shelf life. If storing on the counter, enjoy within about 3-4 days. In the refrigerator, they’ll stay tasty for around 5 days.
For enjoying down the road, these muffins can be frozen. They should last for up to about 2 months.
Recipe Tips
What is the secret to moist muffins?
One way to create moist muffins is to let the batter sit in the fridge for a bit before baking it. You can also make them moister by adding an extra splash of milk or an extra drizzle of coconut oil to the batter.
What apples are best for baking muffins?
When it comes to baking apples, Granny Smith apples tend to be a favorite. Along with those, other top options include Gala and Fuji apples.
What can I add to apple crumble oatmeal muffins?
One thing you can add to your muffins is a sprinkle of cinnamon sugar! This ties in with the cinnamon in the muffins and tastes so delicious with the icing drizzle. You can also add chopped pecans on top!

Holly says
I made these last night! The flavor and muffin texture is great, chewy with the oats that makes a more substantial breakfast paired with yogurt. The only issue I had was with the crumble. With melted coconut oil, it never formed crumble and came out like a paste which just melted into the muffin when baked. Next time will use butter in the crumble, otherwise very good!
