Combine sugar, flour, baking powder, and salt. Set aside.
Beat eggs, milk, and oil until just combined. Gradually add the dry mixture to the wet until just moist. Add apple and cinnamon. Pour the mixture to an inch below the top to compensate for the rise.
Combine cinnamon and sugar. Spoon topping onto each loaf and swirl in with a knife.
Bake for 40 minutes or until a toothpick comes clean.
Notes
Large Loaves: Make this Sweet Bread recipe in 2 (1-lb) loaf pans or cut the recipe in half for just 1 loaf pan and bake 50 minutes or until it passes the toothpick test.
Muffins: Grease miniature muffin tins and fill each to ⅔ full. Bake 12 minutes.
Make it Ornate: Alternatively, you can also bake it in an ornate loaf pan with the same minimal effort!
At Room Temperature: Store quick bread in a sealed plastic bag or covered in saran wrap at room temperature for up to 2 days.
Refrigerate: Store in an airtight container refrigerated up to 5 days.
Freeze: Freeze loaves or slices by wrapping them tightly in heavy foil or plastic wrap. Then place them in freezer bags, and freeze for up to 3 months. Bring to room temperature on a countertop or allow to thaw overnight in the refrigerator. Slice and serve to enjoy. You can even warm it up to get that just out of the oven flavor!
