Preheat oven to 350F and line a baking sheet with parchment paper.
Whisk the flours, baking soda, baking powder and salt together in a medium bowl.
Beat the oil, maple syrup, eggs, and vanilla together in a large bowl on medium speed until combined.
Add the flour mixture to the wet ingredients and beat on low (or use your paddle attachment) until just combined.
Let the dough sit while you make the streusel topping. Mix all the crumb ingredients in a small bowl until combined and the texture resembles wet sand. Start with 1 tablespoon of coconut oil and add more if needed.
Use a medium sized cookie scoop to scoop balls of dough onto the cookie sheet. Use the back of the cookie scoop or the back of a tablespoon measure if the scoop is too big, to flatten and create a small crater in the center of the cookies.
Sprinkle the crumble topping over the cookie base, filling the middle of each cookie, and gently press down so it sticks to the cookies.
Bake for 8-10 minutes, until edges are just golden. Let cool for a couple of minutes before transferring to a wire rack to finish cooling.
Combine the powdered sugar and yogurt to make a simple glaze.
Drizzle icing over cooled cookies and enjoy!
