Recipe step by step instructions:
Step 2: Pour your diced apples into a bowl and add the brown sugar and cinnamon. Mix well to coat all of the apples.
Step 3: In a large bowl, add the dry ingredients. Whisk to blend them. Add the cold butter and use a pastry blender to cut in the cold butter so that you have a crumby mixture.
If you don't have a pastry blender, you can use two knives carefully to cut the butter in.
Step 4: Add in the egg and water and mix. Your crust dough will look like this photo above. You will know you added enough moisture if you use your hands and squeeze the dough. It should hold its shape.
Step 5: Dump ⅔ of the crust mixture into a parchment paper-lined 8x8 baking tin. Use a spoon or your hand to press the crust down firmly so that it is flat.
Step 6: Pour the diced apple mixture over the crust. Spread the apples out evenly over the crust.
Step 7: Add the remaining ⅓ of the crumble mixture and add it on top of the apple layer. You are now ready to bake!
Bake at 350º F for 25-30 minutes.
