To prepare the Undy Arms Hotel sticky toffee pudding desserts recipe, you will need: 1 cup (240 ml) granulated sugar, 2 tablespoons (60 g) softened butter, and 1 teaspoon (2.5 grams) vanilla extract. In a large bowl, mix together the flour, baking powder, cinnamon, nutmeg and salt. Add the wet ingredients to the dry ingredients and stir to combine. Pour the mixture into the graham cracker crust and bake in the oven for 35 to 40 minutes or until the top is golden brown. Allow to cool before cutting into squares.
