  1. Love this! Made it 2 twice, both non dairy. But added a half cup of walnuts the second time. I like to have a good fat with every meal. Thank you for sharing.

  2. Made this last night for breakfast today. Lovely when heated up and a little milk added. Next time I may add a little more cinnamon and perhaps a pinch of cloves and a dash of nutmeg. On the whole, an Excellent Breakfast! Thanks for the recipe! 🙂

    1. I also like to add a bit more milk over the top when serving. I think I will add that to the tip section. Thank you so much!
