Preheat oven to 350 degrees F.
Line a loaf pan with baking paper, or grease with coconut oil.
Add all the streusel topping ingredients to a small bowl, mix to combine, and set aside.
Add all the dry ingredients to a large mixing bowl, mix to combine, and set aside.
Add the coconut oil, eggs, honey and vanilla to a bowl, then set aside.
Peel and thinly slice apples.
Sprinkle the apples with the lemon juice, then add to the bowl with the wet ingredients.
Pour the wet ingredients into the bowl with the dry ingredients, and then stir until most of the dry ingredients are incorporated, being careful not to over stir. Just 10 stirs should be plenty.
Add the batter to the prepared pan, and top with the pumpkin seed streusel topping.
Bake the loaf for 36-40 minutes, until the center of the loaf is set.
Allow to cool for at least 15 minutes before slicing. If the bread is fully cooled in the refrigerator, it makes perfect slices.
Store in the refrigerator for up to a week. I haven't tried freezing this loaf, but am sure it would be fine if frozen and thawed.
