Gradually add sugar and when all is added, beat at high speed for another 15 minutes, or until mixture retains its shape.
Add vanilla, vinegar, and baking powder.

When the cake has cooled, slice off the crusty top and put unsweetened fruit (strawberries or raspberries) along with sweetened whipped cream and replace crust as carefully as you can.
