Preheat the oven to 350 degrees. Spray a loaf pan with cooking spray and set aside.

In a large mixing bowl add the eggs and sugar. Cream together. Add the unsweetened applesauce and vanilla extract. Stir.

Add the cassava flour, gluten-free flour blend, baking soda, ground cinnamon, and sea salt. Stir together.

Add the peeled and sliced apples and fold them into the batter.

Pour the batter into the prepared loaf pan and smooth the top with the back of a spoon.

In a small bowl, add the cassava flour, cane sugar, cinnamon, and two tablespoons of dairy-free butter. Cut the butter into the flour and sugar mixture until a crumble forms. If more butter is needed, add one tablespoon at a time.

Evenly sprinkle on top of the bread batter. Bake the bread for 45-50 minutes, or until a toothpick inserted into the center comes out clean.

Remove from the oven and let cool completely before slicing and serving.
