Pre-heat oven to 400° F. Lightly grease and line a 9.25 x 4.25 inch loaf pan with a parchment sling.
Sift together all of the dry ingredients into a large mixing bowl. Toss 1 tablespoon of the dry ingredients with the apples in a separate bowl and set aside.
Whisk together vegan egg powder with cold water in a medium mixing bowl until smooth. Whisk in brown sugar and melted butter until smooth followed by the rest of the wet ingredients.
Pour wet ingredients on top of the dry ingredients and stir until smooth. Fold in apple chunks until incorporated. Transfer to prepped loaf pan and smooth out the top.
Mix together the streusel ingredients in a small bowl, sprinkle on top of loaf, and lightly press down.
Bake at 400° F until a toothpick comes out clean; about 25 minutes.
Cool in pan for 15 minutes then use parchment sling to transfer to a cooling rack.
Slice and enjoy while warm with a pat of vegan butter or allow it to cool completely and store in an airtight container at room temperature for up to 2 days. Reheat in a broiler until warm; about 1.5 minutes per side.
