Ingredients
 
 

Cake

  • 1 ½ cups Bananas mashed
  • ½ cup Greek yogurt
  • 1 teaspoon Vanilla extract
  • 3 Eggs
  • ½ teaspoon Kosher salt
  • 1 teaspoon Cinnamon
  • 1 ⅓ cups Granulated sugar
  • ⅔ cup Buttermilk
  • 1 stick Butter melted and cooled
  • 3 cups Flour
  • 2 teaspoon Baking powder
  • ½ teaspoon Baking soda

Cinnamon mixture

  • ¾ cup Brown sugar
  • 1 tablespoon Cinnamon

Crumble

  • 1 cup Flour
  • ⅓ cup Brown sugar
  • 1 teaspoon Cinnamon
  • ½ teaspoon Kosher salt
  • 3.1 oz Butter

Instructions
 

Make the crumble topping

  • Into a medium mixing bowl, add the flour, brown sugar, and cinnamon. Mix with a spoon until the mixture is well combined.
  • Add the melted butter and mix until well combined and place in the fridge while you make the cake.

Make the cake

  • Into a big mixing bowl, add the ripe bananas and mash them into a pudding-like consistency with a fork or a potato masher.
  • Into a large mixing bowl, add the mashed bananas, greek yogurt, eggs, cinnamon, sugar, cooled melted butter, buttermilk, kosher salt, and vanilla extract, and mix with a whisk until well combined.
  • Add the flour, baking powder, and baking soda, and mix with a whisk until just combined and there are no lumps of flour visible. Don't overmix.
  • Pour ½ of the cake batter into a parchment paper lined 9 by 13 baking pan and spread it with a spatula.
  • Mix the brown sugar with the cinnamon.
  • Top the cake batter with the brown sugar and cinnamon mixture and spread it evenly. Top with the rest of the cake batter and carefully spread it with a spatula.
  • Top the cake with the streusel topping and press the streusel topping onto the cake batter so it sticks and does not fall off while baking.
  • Bake in a 180c (350f) preheated oven for about 40-45 minutes or until a toothpick inserted into the cake comes out clean, usually with a few crumbs.
  • Drizzle with a simple glaze made with powdered sugar and milk.

Notes

  • Push the streusel topping onto the cake lightly so they would stick to the top of the cake while baking and not fall off.
  • Use room temperature ingredients. It is important that you use room-temperature ingredients like eggs and milk. This step ensures that your mixture mixes into a homogenous mixture and bakes perfectly. you don’t want to place cold batter into the oven.
  • Don’t overmix the batter, you don’t want to develop the gluten in the flour. This step ensures you have moist muffins and not dense and dry cake.
  • Mesure you flour correctly! When measuring your flour, avoid scooping it with a measuring cup. Instead, stir the flour with a spoon to create as many air pockets as possible, and spoon it into your measuring cup. Finally, level it with a back of a knife.
  • Add some of your favorite add-ins! Make this recipe your own and add your favorite muffins add-ins: chocolate chips, chopped walnuts, chopped pecans, chocolate chunks, banana slices, chopped fruit, and more! Be creative!
  • Be patient! I know it's extremely tempting to eat this cake as it is pulled out of the oven, but let this cake cool for at least 1 hour so it will be more firm and won't crumble up.
  • This cake is extra moist and melt in your mouth delicious, so it will be worth it to wait these 15 minutes.
