How To Make Oatmeal Cinnamon Muffins
You’ll see, making them is easy!
All you need to make these healthy oatmeal muffins are a bunch of wholesome ingredients.
- Almond Milk or any milk you love, including soy milk, oat milk, or coconut milk.
- Apple Cider Vinegar or lemon juice
- Old-Fashioned Rolled Oats
- All-Purpose Flour or white spelt flour
- Baking Powder
- Baking Soda
- Cinnamon – I like Ceylon cinnamon, that a stronger flavor than Saigon cinnamon.
- Avocado Oil
- Maple Syrup
- Vanilla Extract
- Unsweetened apple sauce
Cinnamon Oat Crumble
I like to add crunchy oats topping to the muffins. This is optional, but if you want to make it, you need the few ingredients listed below.
- All-Purpose Flour
- Plant-based Unsalted Butter or coconut oil
- Coconut Sugar, brown sugar, or unrefined cane sugar.
It’s not hard at all to make a batch of these cinnamon oat muffins, but you need to follow a few steps to achieve the best fluffy texture.
Soaking The Oats
For these oatmeal cinnamon muffins, you first need to soak the rolled oats with almond milk and apple cider vinegar for 20 minutes.
This step is not optional. It softens the oats and ensures fluffy oatmeal muffins that are not dry.
Preparing The Oat Crumble Topping
Meanwhile, prepare the oat crumble. In a small mixing bowl, add softened unsalted butter, coconut sugar, flour, and oats.
Use a fork to mash the butter into the dry ingredients, then use your fingertips to rub the ingredients together until a crumbly topping forms.
Set aside in the fridge.
Cinnamon Oatmeal Muffin Batter
Next, in a large mixing bowl, whisk all the remaining dry ingredients: flour, cinnamon, baking soda, baking powder, and salt. Set aside.
In another large bowl, whisk applesauce, oil, vanilla extract, and maple syrup.
When the oats have soaked for 20 minutes, it’s time to preheat the oven to 400°F (200°C).
Line a 12-hole muffin pan with paper liners and lightly oil with cooking spray. Set aside.
Finally, to make the muffin batter, fold the wet ingredients into the dry ingredients, including the milk mixture made in step one.
Stir until a lightly thick oatmeal muffin batter forms.
Baking Fluffy Oatmeal Muffins
I like to prebake these muffins for 5 minutes at a higher temperature. This ensures ultra-fluffy oatmeal muffins.
Fill the muffin tin evenly with the muffin batter and bake the muffins for 5 minutes in the center rack of the oven at 400°F (200°C).
Reduce the oven to 350°F (180°C). Keep baking for 15 to 17 minutes, until golden brown on top and a toothpick inserted in the center of the cinnamon oatmeal muffins comes out clean.
Cool down in the muffin cups for a few minutes, then release them on a cooling rack to cool completely at room temperature.
If you feel like it, stir in some nuts, seeds, or some of the below ingredients in the muffin batter before filling the paper cases.
- 1/2 cup of chopped nuts like walnuts, pecans, or almonds go well with cinnamon.
- 1 teaspoon of all spices or pumpkin spices.
- 1/2 cup of fresh blueberries for oatmeal blueberry muffins.
- 1/2 cup of chocolate chips
- 1/3 cup of dried fruits like dried raisins or dried cranberries.
- 1/2 cup of grated carrots
These oatmeal cinnamon muffins are good cold or lukewarm, plain or with a drizzle of:
- A drizzle of nut butter like peanut butter or almond butter.
- Jam like strawberry jam, marmalade, or blackberry jam.
- A sprinkle of extra cinnamon on top
You can store the muffins in an airtight container or sealed cake box and place them in the refrigerator for up to 4 or 5 days.
You can also freeze these cinnamon oatmeal muffins in freezer bags for a month.
Thaw the muffin at room temperature the day before serving. Eat cold, or rewarm in a toaster oven for a few minutes.
Below are some options to adapt this recipe if you have some food allergies.
- Applesauce Swap – Replace the applesauce with one flax egg: stir one tablespoon of golden flax meal into three tablespoons of lukewarm water. Set aside for 10 minutes until thick and add to the recipe instead of applesauce. You can also use 1/4 cup of mashed bananas instead of applesauce.
- Nut-Free – Replace almond milk with any nut-free milk like coconut milk or oat milk.
- Gluten-Free – I didn’t try all-purpose gluten-free flour in this recipe, but it could work with the same ratio. Make sure you also use gluten-free certified oats and wheat-free baking powder.
- Plant-based butter swap – The topping uses plant-based butter. This can be replaced by coconut oil
Frequently Asked Questions
Below are my answers to your most common questions about this recipe.
Not all muffins recipes are healthy. Most muffins recipes are high in sugar and made from bleached white flour only.
But some muffin recipes are healthier, like these oatmeal muffins, because they are packed with fiber and proteins from oats, are refined sugar-free, and use healthy fats from avocado oil.
An oatmeal muffin is higher in fiber and proteins than regular muffins.
It means they keep you full quickly and for a long.
