To make toffee crisps, you'll need: 1 cup (240 g) granulated sugar, 2 tablespoons (60 ml) butter, 1 teaspoon (0.5 tsp) vanilla extract, and 1 tablespoon (2.5 fl oz) milk. In a large bowl, whisk together the flour, baking powder, salt and nutmeg. Add the wet ingredients to the dry ingredients and stir to combine. Pour the mixture into the greased and floured muffin tray. Bake in the preheated oven for 20 to 25 minutes or until the tops are golden brown. Remove from the oven and allow to cool before slicing into squares.
