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 😊

I’ve not tried that to be able to say with full confidence that you could due to the extra moisture it would create?

Try adding small pieces of crystallised ginger or choc chips. Yum.

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 🙂
