This easy Cranberry Oatmeal Muffins recipe is perfect for the season! Every bite is full of sweet orange, tart cranberries, hearty oats, and warm cinnamon spice. They are perfect for a grab-and-go breakfast, or as a sweet treat this holiday season.

These fresh Cranberry Oatmeal Muffins are the best way to use up leftover cranberries this Christmas season! Just mix them into the muffin batter, bake, and enjoy!
They are the perfect balance of sweet, tangy, and wholesome, making them ideal for a make-ahead breakfast. They're hearty and moist muffins that are exploding in flavors!
The streusel sprinkled on top before baking has hints of cinnamon and orange which pairs wonderfully with the muffins! The streusel melts and crisps up so well, I am truly obsessed with the combination.

Step by step instructions
Here is how to make and bake these Cranberry Oatmeal Muffins. You will need a 12 muffin tin, 2 large mixing bowls, muffin liners, a spatula, and a whisk.
Step 1 – Make the streusel. In a medium sized bowl, add flour, oats, cinnamon, sugar, orange zest, and butter. Using your hands, mix this until crumbly and combined, then set in the fridge to chill.

Step 2 – Mix dry ingredients. In a medium-sized bowl, add flour, oats, baking powder, baking soda, cornstarch, cinnamon, and salt. Using a spatula, mix until just completely combined and set aside.
Step 3 - Whisk wet ingredients. Into a bowl, add the brown sugar, oil, orange juice, sour cream, eggs, vanilla, and orange zest. Whisk until well combined (1-2 minutes).
Step 4 - Combine. Add the dry and wet ingredients together and mix until a soft muffin batter forms. Do not over-mix!


Step 5 - Add cranberries. Toss the cranberries in 1 tsp of flour before adding into the bowl. Then add them into the bowl and gently mix in a few times just until the flour disappears.


Step 6 - Scoop. Fill each liner to the top (or halfway if using tulip liners), and sprinkle a generous amount of streusel on top.


Step 7 - Bake. The muffins will bake for 20-25 minutes (25-30 minutes in tulip liners) or until a toothpick inserted in the middle comes out clean. Allow to cool, then enjoy!

Yes. Do not thaw them. Toss the frozen cranberries in 1 tsp of flour, then mix them into the batter, and immediately bake.
