These carrot muffins with streusel topping are moist, lightly spiced, and topped with a sweet, crumbly finish. They’re a cozy, satisfying bake Chef Jenn turns to when she wants something comforting but not overly sweet—perfect for breakfast, brunch, or a snack.
Preheat the oven to 375°F and either line a 12-cup muffin pan with paper liners or grease it well.
Prepare the streusel by mixing the flour, brown sugar, and cinnamon in a small bowl. Use a fork or pastry blender to cut in the cold butter until the mixture resembles coarse crumbs. Place in the fridge to chill.
Combine the dry ingredients for the muffins in a large bowl: flour, baking powder, baking soda, salt, cinnamon, and nutmeg. Stir well.
Whisk the eggs, both sugars, oil, yogurt (or sour cream), and vanilla together in a separate bowl until smooth.
Stir the wet ingredients into the dry mixture just until blended—don’t overmix.
Fold in the grated carrots and walnuts, distributing them evenly.
Divide the batter among the muffin cups, filling each about ¾ full.
Sprinkle the chilled streusel topping generously over each muffin.
Bake for 18 to 22 minutes, or until the muffins are golden brown and a toothpick inserted in the center comes out clean.
Cool the muffins in the tin for 5 minutes, then transfer them to a wire rack to finish cooling.
Notes
Chef Jenn's Tips
Don’t skip chilling the streusel; it helps the topping hold its crumbly texture while baking.
If your brown sugar is lumpy, break it up with your fingers or a fork before mixing.
Add a pinch of ground ginger or clove for a warmer spice profile.
These muffins freeze beautifully—great to make ahead for busy weeks.
