In a saucepan, add the apples, lemon juice, sugar, vanilla, and water and cook on medium-high heat, stirring until they release their juices. Continue cooking until the liquid is reduced considerably. Remove from heat and let cool slightly before adding everything to a high-powered blender and blend until smooth, for about 2-3 minutes.
In a large bowl, combine 1 cup apple puree, vegan butter, Agave, vanilla, and Almond milk-AVC mixture, whisking them together until well combined.
Next, stir in flour, baking powder, baking soda, organic brown sugar, spices, and sea salt and mix until well incorporated! Fold in diced apples. **NOTE: DO NOT OVER-MIX!**
Pour batter in the prepared loaf pan (evenly spreading it out) and make the crumble topping!
