This streusel cinnamon swirl coffee cake is a simple recipe packed with cinnamon flavors. It has a light and moist texture, with an irresistible crunchy cinnamon sugar crumb topping.

Ingredients

Scale

For the cinnamon swirl coffee cake:

  • 5 ounces (140g) plain yogurt
  • ¾ cup (150g) sugar
  • 1/3 cup (80 ml) vegetable oil, neutral in taste (canola, sunflower…)
  • 3 large eggs
  • 1  ¾ cup (210g) all-purpose flour
  • 1 ½ teaspoon baking powder
  • 1 pinch of salt
  • 1 ½ teaspoon ground cinnamon

For the streusel topping:

  • ¼ cup (50g) sugar
  • ¼ cup (30g) all-purpose flour
  • ½ teaspoon ground cinnamon
  • 2 Tablespoons (30g) butter, cold and cubed

Instructions

  1. Preheat the oven to 350°F (180°C) and grease the bottom and the sides of a 9×5-inch (23×13 cm) loaf pan. Set aside.
  2. In a large mixing bowl, pour the plain yogurt. Add sugar, eggs, and vegetable oil. Whisk until combined.
  3. In a separate bowl, mix all-purpose flour, baking powder, and salt. Add the dry ingredients to the wet ingredients, and stir well.
  4. Scoop ⅓ of the cake batter into a small bowl gently stir in the cinnamon until well-mixed.
  5. Pour one layer of the plain cake batter into the prepared loaf pan, then spoon a few spoonfuls of the cinnamon cake batter. Repeat until all the batter has been used up, and make a few gentle swirls by inserting a knife into the batter.
  6. For the streusel topping: Combine the sugar, flour, and cinnamon in a small bowl. Add the cold, cubed butter, and mix with your finger tips. The texture should remain coarse and resemble to thin crumbs (don’t overmix).
  7. Sprinkle the streusel over the cake in an even layer, and bake for about 45 minutes or until a toothpick inserted into the center comes out clean. If the top is browning too fast, tent it with a piece of aluminum foil. Remove from the oven and let cool for about 10 minutes in the pan, then transfer to a cooling rack and cool completely.
