This Easy Homemade Cinnamon Streusel Muffins Recipe is the cozy bake you’ll make again and again after fall turns into winter. These moist muffins feature a buttery streusel with big cinnamon flavor and tender muffin batter. They’re simple enough for a weekend brunch and special enough for an afternoon snack with a cup of coffee.

Streusel Topping In a small bowl, whisk together the streusel dry ingredients of flour, both sugars, cinnamon, & salt. Then pour in melted butter and stir with a fork until it resembles wet sand. Set aside

Muffin In a large bowl (or large mixing bowl), whisk the dry ingredients for the batter: flour, baking powder, baking soda, cinnamon, sugar, and salt. In a separate bowl (medium bowl), whisk the wet ingredients: room temperature Greek yogurt, whole milk, large eggs, oil, and vanilla extract until smooth.

Make a well in the center of the flour mixture and pour in the wet ingredients. Gently fold with a spatula just until you no longer see streaks—overmixing creates dense muffins. The batter should be thick but scoopable; if it seems overly thin, you may have added too much milk or too little flour.

Assembly & Baking Divide the batter among the muffin cups, filling about three-quarters full so the center of a muffin rises nicely. Generously sprinkle the cinnamon streusel topping over each portion. Bake about 20-25 minutes until the tops are golden brown.  Cool in the pan briefly, then transfer to a wire rack to finish cooling.
