Nikki's staple rusk recipe through the years. They are not Ouma standard, but they are great!
Melt butter and sugar, then remove from heat.
Combine dry ingredients in a large bowl.
Add eggs beaten with buttermilk and melted butter and sugar and mix well.
Divide between three greased 9" by 13" pans and bake at 350° F for 45 minutes to an hour.
Turn sheets onto cutting board. Slice into rusk sized portions and place slightly separated on baking sheets - I use four pans for this.
Place in oven at lowest oven temperature for about 12 hours, or till dry.
Store airtight.
