Egg free steamed raspberry pudding

This is an old recipe. Back in the 1940s to the 1970s, my mom used to make individual raspberry puddings steamed in her handleless cups. I can’t recreate it.

I think it had baking soda and/or baking powder in it. I don’t think it had eggs. It was somewhat grayish in color It did not have a golden top or texture and taste akin to a sponge pudding as is true with every raspberry steamed pudding I’ve seen or tried. I remember it had a slight baking powder/soda taste.

Has anyone had this and knows how to make it? My 80-year-old brother and I would love to make it. My budget is nearing its end for buying fresh raspberries in January.
