Mix the brown sugar, cinnamon and melted butter well
Stir in chopped walnuts and set aside
In food processor add dry ingredients, baking powder, flour, white sugar, salt, and pulse until blended
Cut softened cream cheese and butter into chunks and add to food processor and pulse until blended. The mixture will stick together if pressed in your hand.
Put the mixture from the food processor into a large bowl. Make a well in the centre and add the cream, vanilla, and egg. Break the egg yolk and blend slowly, just until everything is moistened. Like when you are making muffins.
Preheat the oven to 375 and grease and 8 X 8 square pan.
Press the cake mixture into the plan
Add small chunks of cream cheese around the top – I push them in slightly with my finger!
Spoon on the brown sugar topping (this will sink into the cake as it bakes)
Bake for 30 to 35 minutes.
Let cool and Enjoy with a smoky dark coffee.
