This Cinnamon Streusel Yogurt Coffee Cake is the ultimate cozy bake—moist, tender, and layered with a buttery cinnamon crumble that melts into every bite. Greek yogurt keeps the texture light yet rich, while the cinnamon-sugar swirl gives it that classic coffee cake feel. Perfect for brunch, holidays, or slow mornings at home.
For the Cake
1 1/2 cups all-purpose flour
1/2 teaspoon baking soda
1/2 teaspoon baking powder
1/4 teaspoon salt
1/2 cup cane sugar
1/4 cup coconut sugar or brown sugar
1/2 cup butter or coconut oil, melted
2 eggs
1 cup Greek yogurt (plain or vanilla)
1 teaspoon vanilla extract
For the Streusel
1/3 cup brown sugar
2 tablespoons flour
1 teaspoon cinnamon
2 tablespoons cold butter, cubed
Preheat oven to 350°F (175°C). Grease or line an 8×8-inch baking dish.
In a bowl, mix flour, baking soda, baking powder, and salt.
In another bowl, whisk sugars, melted butter, eggs, yogurt, and vanilla until smooth.
Fold in dry ingredients until just combined.
For the streusel, combine brown sugar, flour, and cinnamon, then cut in butter until crumbly.
Pour half the batter into the pan, sprinkle half the streusel, then repeat with remaining batter and streusel.
Bake for 35–40 minutes, or until a toothpick comes out clean. Cool before slicing.
