Equipment

  • 9x13 baking dish
  • parchment paper
  • 3 mixing bowls
  • Measuring cups and spoons
  • Whisk
  • Handheld mixer or pastry blender
  • Rubber Spatula

Ingredients

For the filling

  • ½ cup cane sugar
  • 2 tsp ground cinnamon
  • 1 tsp all purpose flour

For the crumb topping

  • 4 tbsp butter room temperature
  • ½ cup cane sugar
  • ¾ cup brown sugar
  • tsp ground cinnamon
  • ¼ tsp salt
  • ¼ cup all purpose flour

For the cake

  • 1 stick butter room temperature
  • 1 cup cane sugar
  • 1 cup Greek yogurt
  • 3 eggs
  • 1 tsp vanilla extract
  • 2 cups all purpose flour
  • 1 tsp baking soda
  • tsp baking powder
  • ½ tsp salt
  • cooking spray

For the icing

  • 2 cups Powdered Sugar
  • 2-4 tbsp milk
  • 1 tsp vanilla extract

Instructions

  • Preheat oven to 350°F. Then, line a 9x13 pan with parchment paper and spray with cooking spray. 
  • You will need three separate mixing bowls for this recipe ranging from small to medium size. The cake batter will be the most voluminous, so save the biggest bowl for that batter.

First, let's make the filling:

  • In a mixing bowl, combine sugar, ground cinnamon, and flour. Whisk until completely folded together. Set the bowl aside.

Next, we'll make the crumb topping:

  • In another mixing bowl, combine room temperature butter, sugar, and brown sugar. You can do this with a pastry blender or use a handheld mixer on low. Fold in ground cinnamon, salt, and all purpose flour. Set aside. 

Finally, make the cake batter:

  • In your largest mixing bowl, use a hand mixer to blend a stick of room temperature butter and cane sugar. Then, add in Greek yogurt, eggs, and vanilla extract. Blend until the wet mixture is completely combined.
  • Next, add in all dry ingredients: all purpose flour, baking soda, baking powder, and salt. Blend again until combined. 

Now, let's layer:

  • Add half of the cake batter to your greased pan. It’s going to be sticky, so I suggest using a rubber spatula to dollop a little into the pan at a time.
  • Next, add all of the filling. It will feel like you're adding too much, but it’s good to have a solid cinnamon sugar filling to get that cinnamon line throughout.
  • Add the remaining cake batter into the pan by dolloping with a rubber spatula. Take your time to really spread it all out. Try not to mix it with the cinnamon sugar layer. See the images in my post above if you need a demonstration.
  • Lastly, add the crumb topping to the top of the batter.

Time to bake!

  • Bake for 30-40 minutes. Depending on what size pan you use, watch the coffee cake closely in the final minutes. Put a toothpick through the middle to ensure it’s baked all the way through.

For the icing:

  • In a mixing bowl, use a high speed hand mixer to beat powdered sugar, vanilla extract, and milk together until a glaze icing forms. Add tablespoons of milk one at a time until desired texture is reached.
  • Drizzle onto slightly cooled coffee cake and enjoy!

Notes

Let cool, then store in an airtight container on the counter for two to three days or in the refrigerator for one week. Be sure to keep it covered. If you don't, it'll dry out quickly.
Coffee cake batter is thickkkkk. That's what makes it so good! When you’re pouring the coffee cake batter into your greased pan, you'll find it fairly sticky. I recommend spraying a rubber spatula with cooking spray to prevent sticking and adding the cake batter to the pan in small clumps. This will allow for smooth spreading. Also, it's important you use three separate bowls! Keeping each layer separate is key.
