For the coffee cake:

For the streusel topping: 


  1. Start by preheating the oven to 350F. Grease and line a 9x9in baking dish with parchment paper. 
  2. Beat together the butter and sugar until creamy, about 1 minute. 
  3. Add in the eggs, one at a time, scraping the bowl after each addition. 
  4. Then, add the vanilla and mix the wet ingredients together well. 
  5. In a separate bowl, whisk together the flour, baking soda, baking powder, and salt. Pour the dry ingredients into the wet in 2 parts, mixing just enough to combine well. 
  6. Add the Greek yogurt and milk to the batter and stir until just combined. 
  7. Toss the blackberries in the flour until they’re just dusted. This keeps them from all sinking to the bottom. Set aside. 
  8. Mix together the streusel topping ingredients until everything is clumpy and sandy. Set aside.
  9. Pour half of the coffee cake batter into the lined baking pan. Top with all of the blackberries and half of the streusel mixture. 
  10. Pour the remaining batter over the blackberries and top with the remaining streusel. 
  11. Bake in the preheated oven on the middle rack for 42-50 minutes or until the cake bounces back a bit when touched in the middle and a toothpick comes out clean. 
  12. Cool in the pan until room temperature. Slice and serve!
