This recipe makes perfect pancakes too, so don't worry if you don't have a waffle maker:) This is recreation by me from 'The Little Swedish Kitchen' by Rachel Khoo.
Mix or mash the butternut squash.
Add the butter, buttermilk, milk and eggs and mix well.
Add sifted flour, baking powder, cinnamon and salt to the batter and gently mix. Don't overmix, some lumps are advisable.
Bake in the waffle maker according to the manufacturer instructions or if you are making pancakes, fry for a couple of minutes until risen and fluffy.
Serve with toppings of your choice. I love it with bacon, tomatoes and creme fraiche.
