Tender, moist Cranberry Muffins with Walnut Streusel! Made with fresh cranberries these muffins are sweet and tart with a crunchy sweet topping. This is the perfect muffin for a cool fall breakfast.
Preheat the oven to 425°F (you will reduce the temperature to 350°F after the muffins bake for 5 minutes)
Coat a 12-cavity standard-size muffin tin, or use paper baking cups.
In a medium size bowl, whisk the dry ingredients together and set aside.
In another bowl, beat the sugar, butter, oil and eggs together to combine. Add the sour cream and vanilla and beat until well blended.
Pour the wet ingredients into the bowl of dry ingredients. Measure the cranberries into a small bowl and toss with 1 tablespoon of flour; then, using a rubber/silicon spatula gently fold in the cranberries until the batter is combined. Do not over mix the batter.
Make the Streusel Topping:
Blend the walnuts, flour, sugar and butter together and stir until you have small pea-sized clumps.
Fill the muffin tins completely full then sprinkle the tops with the streusel topping.
Transfer to the oven and bake for 5 minutes at 425°F; then reduce the temperature to 350°F and bake for 12-15 minutes or until a toothpick inserted in the center comes out clean.
Allow the muffins to cool completely before removing them from the pan.
Notes
Coat cranberries in flour: Lightly toss cranberries with flour before folding into the batter. This keeps them suspended so they don’t sink to the bottom.Use frozen cranberries straight: Frozen cranberries work just as well as fresh. Do not thaw frozen berries before adding to the batter.Choose full-fat sour cream: It gives the batter richness and keeps the muffins moist with a tender crumb.Start hot for tall tops: Bake at 425°F for the first 5 minutes to create a quick rise and bakery-style domes. Then reduce the oven temperature to 350°F to finish baking.
