Vintage Recipe for Biscuit Bread Pudding?

I have been looking for years for a recipe my grandma made. She started with a can of biscuits in a casserole dish, she added a mixture of egg, milk, sugar, and I don't know what else. We had it for breakfast. It sounds like some type of bread pudding, but I can't replicate the taste even close. Does this sound familiar to anyone? Your help would be appreciated. Since my mother passed, there's no one who knows the recipe.
