Ingredients

Oats. Quick, minute or rolled! Any oats will work for these oats cups.
Collagen Powder. I love adding collagen powder to these apple oatmeal muffins for a little extra protein boost. However if collagen is not something you have on hand you can easily substitute with any unflavoured or vanilla protein powder or a little bit of oat flour!
Apple Pie Spice. Buy a pre-made apple pie spice. Or make your own using ginger, nutmeg and cinnamon following the measurements in the recipe below!
Maple Syrup. For a touch of natural sweetness! I have never tested these muffins with any other sweetener. However I am sure honey would also work (if you try let me know in the comments)!
Apple Sauce. I add apple sauce to this recipe for some added apple flavour. I love using an unsweetened apple sauce because I find it's already sweet enough without additional sugar!
Eggs. I use a full egg in this recipe. This helps to find together the oats with the spices and other dry ingredients. If you are vegan or are unable to consume eggs feel free to substitute with a flax egg. You can make a flax egg by combining 1 tablespoon of ground flax seeds with 3 tablespoon water and allowing it to sit for 15 minutes.
Apple. Feel free to use any variety of apple you like! I personally love honey crisp apples but red delicious, Cortland, gala any will work just fine.
The complete ingredient list with measurements can be found in the recipe card below.
Instructions
- Preheat oven to 350F and line a muffin pan.

- In a large mixing bowl, combine dry ingredients. In a separate bowl, mix together the wet ingredients (except the diced apples!)

- Slowly add the dry ingredients to the wet, and stir until well combined. Fold in the diced apples.

- Fold in the diced apples.

- Evenly spoon batter into each muffin cup. Bake for 24-27 minutes.
Substitutions and Variations
To make gluten-free: this recipe is naturally gluten free if you use gluten free oats! I recommend Bobs Red Mill!
To make vegan: you can replace the milk with a non dairy milk of choice (soy milk is good for more protein) and the egg can be replaced with a flax egg (1 tablespoon ground flax + 3 tablespoon warm water) .
To make nut-free: I have not tested a nut free version but you can try to experiment by replacing the peanut butter with an equal amount of seed butter!
Storage
These Apple Oatmeal Muffins can be stored in the fridge in an airtight container for up to a week or freeze and microwave for up to 2 months!
Top Tips for Success
Dice your apples nice and small! I find when the pieces of apple are too large the muffins tend to fall apart a bit easier than smaller bites!
I recommend using a cooking variety of apple such as a crisp apple (honey crisp, gala, pink lady etc.) for the most flavour and texture!
Frequently Asked Questions
Breakfast isn't the most important meal of the day. All meals matter because they fuel your body! SO my message is please do not skip breakfast, or lunch or even dinner!
I know mornings can be hectic, but taking a few minutes to eat can make a big difference! Recipes like these apple oatmeal muffins make it simple. With just 10 minutes of prep, you'll have an easy grab-and-go breakfast ready for the week!
You should be able to substitute ½ of the milk with Greek yogurt though if you find the batter a little on the dry side before adding it to the muffin tin just add another splash of milk!
I dont recommend adding any additional protein powder/collagen as it may react differently while baking.
