Preheat oven to 350°F and line a baking sheet with parchment paper.
In a large mixing bowl, whisk together almond butter, maple syrup, egg or chia egg, and vanilla extract until smooth.
Add almond flour, baking powder, cinnamon, and salt; mix until a thick, slightly sticky dough forms.
Using a double cookie scoop, form dough into large balls, then flatten on the prepared baking sheet.
Grease the back of a tablespoon and make an indent in each cookie.
In a small bowl, combine all crumble ingredients, then sprinkle over each cookie.
Bake for about 15 minutes until edges are slightly firm. Allow to cool completely.
Drizzle icing over cooled cookies and enjoy!
