Instructions

For the topping:

  • Mix the flour, brown sugar, cinnamon, and salt in a medium mixing bowl. Add the warm melted butter and stir to blend.
  • Squeeze a handful of the topping into your hand, if it doesn't clump together, add some more melted butter until it does. Set aside.

For the cake:

  • Preheat the oven to 350f/175c.  Grease 9x13 inch baking pan
  • In a medium mixing bowl mix together the flour, baking soda, baking powder, and salt.
  • Beat the softened butter in a large bowl until light.
  • Add sugar and beat until light and fluffy.
  • Add eggs 1 at a time, beating until well blended after each addition.
  • Add buttermilk and vanilla, beat just until blended.
  • Add flour mixture in 3 additions, beating just until blended after each addition.
  • Transfer cake batter to prepared baking pan (the batter will be thick); spreading it evenly over the pan.
  • Hand-squeeze small handfuls of topping together and crumble clumps evenly over cake batter, covering with a thick layer of topping.
  • Bake 45 minutes to an hour or until the tester comes out clean and topping is deep golden brown and a little crisp.
  • Cool cake in dish on rack at least 30 minutes.  Dust with powdered sugar and cut into squares to serve.

Notes

  • Make the topping first.  Leaving the batter to sit before baking may cause problems with rising, causing the topping to sink into the cake.
  • Use good quality unbleached flour (with4-5g of protein) for the best result.  Lower quality flour may not have the stability to hold the topping.
  • Don't overmix the batter once the flour is added.  Overmixing can cause a tough, dense cake.
  • Be sure to cool the cake completely before dusting with the sugar.  A warm cake will melt the sugar.
