Cranberry Oat Muffins

Homemade Cranberry Oat Muffins – Cozy, Sweet, and Perfect for Breakfast

There’s something so comforting about a batch of warm muffins fresh out of the oven, and these Cranberry Oat Muffins hit all the right notes. They’re hearty from the oats, slightly tart from the cranberries, and finished with a buttery walnut streusel that adds just the right amount of crunch. Perfect for breakfast, snack time, or when you just want something homemade and cozy without spending all morning in the kitchen.

Ingredients and Why They Work

All-purpose flour gives the muffins structure and keeps them fluffy. Salt balances the sweetness and enhances the overall flavor. Baking powder and baking soda give the muffins lift, making them tender and soft. Rolled oats add heartiness and a subtle chew that makes these muffins feel wholesome and satisfying. Egg binds the batter together and helps the muffins rise.

Granulated sugar adds sweetness, while brown sugar gives them warmth and depth with a hint of molasses flavor. Greek yogurt adds moisture and tang, keeping the muffins soft for days. Vegetable oil ensures a tender crumb and makes the muffins light. Cranberries bring bursts of tart flavor that balance the sweetness perfectly.

For the streusel topping, flour helps create a crumbly texture, sugar sweetens it just enough, cinnamon brings warmth, cold butter makes it crispy and golden, and walnuts add a nutty crunch that complements the cranberries beautifully.

How to Make Cranberry Oat Muffins

Start by preheating your oven to 400 degrees and lining a muffin tin with paper liners. In a large mixing bowl, sift together the flour, salt, baking powder, and baking soda to make sure everything is evenly distributed. Stir in the rolled oats and set the dry mixture aside. In a separate bowl, whisk the egg, granulated sugar, and brown sugar until smooth and slightly creamy—this step helps create a lighter muffin texture. Add the Greek yogurt and vegetable oil, mixing just until everything is well combined. Be careful not to overmix—this is key to soft muffins! Gradually add the dry ingredients to the wet, stirring gently until the batter comes together. Fold in the frozen cranberries, making sure they’re evenly distributed throughout the batter.

Scoop the batter evenly into the muffin liners, filling each about three-quarters of the way. To make the streusel, mix together the flour, sugar, cinnamon, and butter in a small bowl using a fork until the mixture is crumbly. Stir in the chopped walnuts, then sprinkle the streusel mixture generously over each muffin. Bake for about 20 minutes or until a toothpick inserted into the center comes out clean. Let the muffins cool slightly before transferring them to a wire rack.

I made these one chilly fall morning when I realized we were out of cereal and the kids wanted something warm before school. I threw together what we had—oats, yogurt, cranberries—and hoped for the best. By the time they came out of the oven, the house smelled like a cozy bakery, and everyone was waiting at the counter with plates ready. My husband grabbed one to go, my youngest picked off all the streusel first (because priorities), and now these muffins have become a weekend staple.
