Imagine a toffee apple dipped in white chocolate - now have that luscious taste in a moist and airy gluten free muffin! Butterscotch chips are available in most supermarkets in the baking aisle. This recipe makes 24 muffins but it's easily halved if you need fewer.
The butterscotch chips will melt down through the muffins during baking. Piling them into the centre of each muffin will provide a column of toffee flavour through the middle; or, you can spread them over the whole top for more even distribution.
