advice/suggestions re slice base please

[KarenH]

Hi everyone,
I have been given a lovely recipe for a german Kutchen slice, which I have made several times.  The recipe for the base says to use 1 packet of commercial buttercake mixture, which you rub with butter to make a crumbly dough mixture that you press firmly into a tin and bake 20 mins and letting cool before adding the topping.

can anyone suggest an alternative for the commercial cake mixture to rub with butter?  I was thinking of plain flour and sugar, but am not sure if I should be adding anything else.  And I am not sure what quantities or proportions to add them in to make up the equivalent of a packet of commercial cake mix.

Thanks in advance!
Karen

Karen, that reminds me of the method in the Armenian Nutmeg cake recipe that I have. In that recipe, you combine 2 cups of brown sugar and 2 cups of SR flour, and rub together with 4 ounces of butter until it resembles breadcrumbs. You sprinkle half of the mix into a lined, 8" square tin and then continue adding wet ingredients to the dry and pour over the base and cook.

Karen,  I think that is the recipe that won a Bake Off competition some years ago.  I think ES is  correct.

Thanks ES and ACW  - will try that one and see how it goes.  The Armenian Nutmeg cake sounds wonderful ES!
