Preheat oven to 350 degrees F and spray a 9x5 loaf pan with non-stick spray and set aside.

In a medium-sized mixing bowl whisk together all-purpose flour, ground cinnamon, baking soda, and kosher salt, and set aside.

In a large mixing bowl with a hand-held mixer or the bowl of an electric mixer, add granulated sugar and unsalted butter and cream together until light in color and fluffy.

Add in eggs and incorporate fully.

Mix in milk and vanilla extract.

Fold in apples until incorporated.

Pour half of the batter into the prepared pan, add half of the streusel topping on top of half the batter, carefully add the remaining half of the batter to the top of the streusel, and spread evenly over the top.

Add the remaining streusel topping over the top of the batter.

Bake for about 60 minutes or until a toothpick comes out clean when tested in the center of the bread. A few dried breadcrumbs on the bread is ok but you should see no liquid batter on the toothpick.

Let the bread rest for 15 minutes in the pan and then remove the bread from the pan and let cool on a wire rack.

When fully cooled, slice and enjoy.

Add all ingredients to a mixing bowl and either using a fork, or your hands, mix together until crumbly and combined. This mixture will resemble wet sand.

Set aside until ready to be used.
