Easy Carrot Oatmeal Streusel Muffins are filled with carrots, brown sugar, and hearty oats in each bite. The muffins come together with no electric mixer and are sprinkled with a buttery sugar streusel before baking. They are irresistibly good!

The texture of carrots and oatmeal is unbelievable! These muffins have fresh carrots grated in, chewy oats, and warm spices.
My favourite part about these muffins is that you don't need an electric mixer to bake them. It all gets mixed together with either a whisk or a spatula.

Ingredients Notes
Here are a list of the ingredients needed for these Carrot Oatmeal Streusel Muffins. Continue scrolling for a detailed step-by-step with measurements in the recipe card.
- Applesauce - You can use unsweetened or sweetened. If you use sweetened, your muffins will be a tad sweeter (obviously).
- Brown sugar – Dark brown sugar or light brown sugar works.
- Baking soda & baking powder - Make sure they aren't expired!
- Carrots - These should be finely grated. Pre-cut carrots won't work, they have to be freshly grated.
- Cinnamon - An essential spice in these muffins! I also used a hint of cloves, ginger, and nutmeg as well for more flavours, but these are optional.
- Cornstarch – This helps add a tender crumb to the muffins.
- Eggs – Make sure the eggs are at room temperature. You can bring them to room temperature quickly by placing them in a bowl of warm water.
- Oil - Any flavourless oil works.
- Flour – I used all-purpose flour in the muffins.
- Oats - Use rolled oats, also known as large flake oats. Quick oats are to small and won't work.
- White sugar - Make sure it's granulated sugar and not powdered sugar.
- Vanilla – Using a good quality vanilla is important to enhance the flavours.
Step by step instructions
Here is how to make and bake these Carrot Oatmeal Muffins. You will need two 12 muffin tin, muffin liners, 3 mixing bowls, a spatula, and a whisk.
Step 1 – Prep. Line your muffin tin with 14 muffin liners and set aside. If you need a recommendation, this is my favourite tin.
Step 2 - Make the streusel. In a medium-sized bowl, add flour, butter, cinnamon, oats, brown sugar, and white sugar. Mix together with a fork or your hands until combined into big and small pieces. Place in the fridge to chill while you make the muffin batter.
Step 3 – Mix together dry ingredients. In a medium-sized bowl, add in oats, flour, salt, cornstarch, cinnamon, nutmeg, ginger, cloves, baking powder, and baking soda. Using a spatula, mix until just completely combined.
Step 4 - Grate the carrots. Using the fine side of your grater, grate the carrots.
Step 5 – Mix wet ingredients. In a large bowl add shredded carrots, unsweetened applesauce, eggs, vanilla, brown sugar, oil. Whisk until combined.
Step 6 - Add dry ingredients. Add the dry into the wet and using a spatula, gently mix until just combined. Don't over-mix!
Step 7 - Scoop. Scoop the muffins evenly between 14 regular liners. This recipe makes 13-15 muffins depending on how full you fill each liner. Sprinkle a handful of streusel on top of each muffin.
Step 8 - Bake. Bake the muffins for 20-25 minutes in regular liners or until a toothpick inserted comes out clean.
These carrot oatmeal streusel muffins are so delicious! They stay good on your counter for up to 3 days and in the fridge in an airtight container for up to a week.
