  1. I had to make these the same day Paulene posted the recipe. She had me just with peanut butter 🙂 These were amazingly delicious and super easy to make. 3 simple ingredients most often on hand and yes they rose high even though there was no flour! Cant wait to make and share

    Thanks Paulene 🙂

  2. I’ve done this in the microwave before for one but I think it would be perfect in the slowcooker to make a few of them. Looking forward to trying this, thanks Pauline ?
