Step 1

Preheat oven to 350F. Spray one 9x5-inch loaf pan very well with floured cooking spray or grease and flour the pans; set aside.

Step 2

Crumble Topping - To a medium bowl, add the melted butter, 1/3 cup flour, sugars, cinnamon salt, and fluff very lightly with a fork to combine until small marbles and pebbles form. Tip - You are not ‘stirring’, you are fluffing lightly and gently. If the topping is very wet and is not fluffing into small pebbles and marbles and is more like wet sand, add additional flour up to 1/2 cup total, or as necessary, to create a streusel; set aside.

Step 3

Bread - To a large bowl, add egg, brown sugar, oil, granulated sugar, sour cream or Greek yogurt, vanilla, cinnamon, ginger, nutmeg, and whisk to combine.

Step 4

Add the flour, baking powder, baking soda, salt, and fold with spatula or stir gently with a spoon until just combined; don’t overmix.

Step 5

Add the grated apples (you don't need to wring them out like you would with zucchini), and fold gently to combine.

Step 6

Turn the batter out into the prepared pan, smoothing the top lightly with a spatula.

Step 7

Evenly sprinkle with the reserved crumble topping.

Step 8

Bake for about 45 to 52 minutes (I baked 48 minutes) or until a toothpick inserted in the center comes out clean, or with a few moist crumbs, but no batter. Tip - I recommend tenting the pan with a sheet of foil draped loosely over it at the 30 to 35-minute mark so the tops and sides don't become too browned before center cooks through.

Step 9

Allow bread to cool in pan for about 30 minutes before turning out on a wire rack to cool completely before slicing and serving.*
