Banana Nutella Swirl Cake

No picture sorry. My sister Katie found this recipe on a blog (http://www.twopeasandtheirpod.com/) It is DELICIOUS and even better the second day!

For the cake:
2 cups all-purpose Gold Medal flour
1 tsp baking soda
1/4 tsp salt
1/2 cup unsalted butter, at room temp
1 1/2 cups granulated sugar
2 large eggs
1 cup plain greek yogurt
1 tsp vanilla extract
3 ripe bananas, peeled and mashed (to equal 1 cup)
1/2 cup Nutella

Preheat oven to 350. Grease a 9x13 pan and set aside.

In a medium bowl, whisk together the flour, baking soda and salt. Set aside.

In a large bowl, cream together the butter and sugar until creamy and smooth, about 3 min. Beat in the eggs, one at a time, then stir in the yogurt and vanilla extract. Mix in the mashed bananas.

Gradually add the dry ingredients and mix until flour disappears. Spread cake batter evenly into the prepared pan. Swirl the Nutella into the cake using a knife or toothpick.

Bake for 20 to 25 min (mine took closer to 35-40), or until a toothpick inserted into the center comes out clean. Allow cake to cool completely.

For the frosting:
1/2 cup unsalted butter, at room temp
1 cup Nutella
1 1/2 cups powdered sugar
2-3 Tbsp milk
1/2 tsp hazelnut extract, optional (I didn't have any so I didn't use it)

Beat the butter and Nutella on high until smooth. Slowly add the powdered sugar 1/4 cup at a time. Alternate adding powdered sugar and milk and beat on high until powdered sugar is incorporated. If you need to add more milk, add a little bit at a time to get to desired consistency.

Frost the cake with the Nutella frosting, cut into squares and serve. (Very important: keep some in the pan for yourself for breakfast the next day!!)
