  1. Preheat oven to 350°F. Lightly coat a 9-inch square baking pan with cooking spray; reserve.
  2. Prepare the Crumb Topping: Put all of the crumb topping ingredients in the Cuisinart® mixing bowl. Attach the flat mixing paddle and mix on Speed 2 to break up, scrape if necessary and then increase to Speed 4, until the mixture resembles large crumbs. Remove and reserve in refrigerator until ready to use.
  3. To prepare the Buttermilk Cake: Put the flour, baking soda, cream of tartar and salt in a medium bowl and stir to combine; reserve.
  4. Put the butter and granulated sugar in the Cuisinart® mixing bowl. Attach the flat mixing paddle and mix on Speed 3 until incorporated. Scrape the entire bowl, increase to Speed 5 and mix until light and fluffy, about 1 minute.
  5. Scrape the bowl well and reduce speed to 3. Add the egg and the vanilla extract and mix until fully incorporated and batter is smooth. Scrape the entire bowl.
  6. Add half the reserved dry mixture and half the buttermilk. Mix on Speed 2 until just blended. Scrape the entire bowl. Add remaining dry ingredients and buttermilk. Continue mixing on Speed 2 until smooth and blended.
  7. Pour batter into prepared pan and smooth over top. Sprinkle blueberries evenly over the top; lightly press blueberries into batter (submerge blueberries slightly). Crumble any large clumps in the crumb mixture and sprinkle the crumb mixture evenly over the blueberries.
  8. Bake in preheated oven until crumbs are evenly golden brown and tester is clean when inserted in center of pan, about 30 to 35 minutes. Remove from oven and cool on a wire rack before cutting.
