First, preheat your oven to 350?. Then, spray a 9"x5" standard loaf pan with non-stick spray and set it to the side. 

In a large mixing bowl, beat the butter and sugar together until smooth. 

Beat the eggs in 1 at a time. Then, mix in the vanilla. 

Next, mix in the baking powder and flour just until blended. 

Add your Greek yogurt and milk into the batter. Gently mix until smooth and set the batter aside. 

In a separate mixing bowl, stir together the brown sugar and cinnamon to make the apple coating. Set aside. 

In another bowl, mix together the brown sugar, cinnamon, and sugar for sprinkling. 

Peel and dice your apples, and then add them to the sugar and cinnamon mixture. Coat the apples evenly. 

Pour half of the bread batter into the loaf pan. Then, add a layer of half the apple mixture. 

Sprinkle ½ of the  brown sugar, cinnamon and sugar mixture on top of the apples. Then, swirl a knife through the layers. 

Repeat step 9 & 10 one more time. Batter, then apple mixture, then end with the brown sugar-cinnamon mixture.  Again, use a knife to swirl through the layers. 

Put the loaf in the oven and bake for 50-minutes. Check it with a toothpick. If it doesn’t come out clean, cook the bread for 5-minutes at a time checking after each 5-minutes. 

Allow the loaf to cool for 30-minutes before adding the glaze. 

While the loaf is cooling, whisk together the powdered sugar, cream, and vanilla until smooth. 

Add the glaze and Enjoy!
