I am going to have to try these; they seem way too easy!
Reminds me of the 3 ingredient pumpkin chocolate chip muffins I used to make.
1 can (15oz) pumpkin puree
1 cup chocolate chip
1 box vanilla cake mix (just the mix, don't add the cake ingredients)
Mix together, put in muffin tins and bake at 350 for about 20-25 min. Easy peasy.
You can easily get canned pumpkin in the UK too.
