Moist Cinnamon Streusel Muffins Recipe for Perfect Breakfast

What makes this recipe worth trying:

• They’re perfect for grab-and-go breakfasts when mornings are hectic.
• The muffins stay moist thanks to sour cream (or Greek yogurt) and whole milk, while the streusel adds a satisfying crunch.
• Homemade muffins let you control ingredients and save money while keeping the bakery flavor.

Ingredients and substitutions

• All-purpose flour
• Baking powder
• Salt
• Ground cinnamon
• Vegetable oil: can be swapped for a neutral oil like canola or grapeseed; avoid olive oil because its flavor is strong.
• Brown sugar: used in the batter, filling, and streusel; light or dark both work.
• Eggs: bring to room temperature for easier incorporation.
• Vanilla extract: use pure vanilla for best flavor.
• Milk: whole milk gives the best, fluffy texture; lower-fat milks will yield slightly different results.
• Sour cream or plain Greek yogurt: full-fat adds moisture and richness.
• Butter: room-temperature unsalted butter is best for the streusel so it forms crumbs easily.
• Rolled oats: old-fashioned oats add texture to the streusel.
• Confectioners’ sugar: for a smooth glaze—sift if clumpy.

Step 1

Mix the filling ingredients in a small bowl and set aside. In another bowl combine the streusel ingredients and, using clean hands or a fork, squeeze the mixture until coarse clumps form. Set the streusel aside until ready to top the muffins.

Step 2

Preheat the oven to 425°F. Line a 6-cup jumbo muffin pan with liners or spray with nonstick spray. For standard muffins, use a 12-cup muffin tin and liners or spray.

Step 3

Whisk the dry ingredients—flour, baking powder, salt, and cinnamon—in a large bowl and set aside.

Step 4

In a separate bowl, stir together the vegetable oil, brown sugar, eggs, milk, sour cream, and vanilla until well combined.

Step 5

Gently fold the dry ingredients into the wet mixture until no dry streaks remain, taking care not to overmix.

Step 6

For a jumbo muffin tin, spoon ¼ cup batter into each cup. For standard muffins, use 2 tablespoons of batter per cup. Add the cinnamon-sugar filling—2 teaspoons per jumbo cup or 1 teaspoon per standard cup—then cover with an equal amount of batter (another ¼ cup for jumbo, 2 tablespoons for standard).

Step 7

Top each muffin with a generous amount of streusel, dividing it evenly over the tops.

Step 8

Bake at 425°F for 5 minutes, then reduce the oven temperature to 350°F and bake an additional 15 minutes for standard muffins or 18–20 minutes for jumbo muffins, until a toothpick inserted into the center comes out clean and the tops are golden.

Step 9

Let the muffins cool in the pan for 10 minutes, then transfer them to a wire rack to cool completely.

Step 10

Whisk the glaze ingredients until smooth and drizzle over the cooled muffins just before serving for a sweet finishing touch.
