My mother, Irma, was a great cook. She never used recipes and it was always a challenge to document what was going on in her kitchen. I had pencil, paper and measuring cups handy and would measure or weigh ingredients after she pulled everything together. This was one of her most popular cakes, like a coffee cake that works for morning coffee, but also like a crumble to serve with afternoon coffee and great with a scoop of ice cream for an after-dinner dessert.
