How to make it

  • Preheat oven to 350.Lightly grease a 9X13 inch pan.
  • Make the stresuel topping.Mix all dry ingredients,then stir in melted butter until well combined.Set aside.
  • Sift the flours,potato and tapioca starch,plus the xanthan & /or guar gum for the cake batter over a large bowl.Stir with fork in bowl so that all is well mixed,set aside.
  • In a medium size bowl,make the filling by mixing the above listed ingredients together,set aside.
  • In a large bowl,beat the butter,salt,sugars,baking powder and vanilla,until well combined and smooth.
  • Add the eggs,one at a time,beating well after each addition.
  • In a seperate bowl,whisk together the milk and sour cream until well combined.You dont need to whisk out all the lumps.
  • Add the flours to the butter/sugar mixture alternately with the milk/sour cream mixture,beating gently to combine.
  • Pour/spread half the batter,about 3 cups on the bottom of pan,spreading all the out to the edges.
  • Sprinkle the filling evenly over the batter.
  • Spread remaining batter atop the filling.Use a table knife to gently swirl the filling into batter,as though making a marble cake.Dont combine the filling and batter thoroughly;just swirl the filling through batter.
  • Sprinkle topping over batter.
  • Bake cake until dark golden brown around edges;medium golden with no light patches showing on top,and a toothpick inserted in center comes out clean-About 50-60 minutes.( mine took a little under 50 )
  • When pressed gently,center should spring back.
  • Remove cake from oven,allow to cool for 20 minutes before cutting and serving.
  • Note:I have been using guar gum more recently as I am almost out of xanthan gum.I have had very good results,texture and moistness-wise using a ratio of1/2 guar & 1/2 xanthan gum.
