In a mixing bowl, beat together sugar and butter until light in colour and fluffy, about 3 minutes. Beat in sour cream and then eggs one at a time. Add 20 drops Coffee Espresso Flavour, 20 drops Crispy Doughnut flavour, and 15 drops Vanilla Cookie flavour and mix well.
In a separate bowl, stir together flour, baking soda, and baking powder. Add dry mixture to wet ingredients and mix until well combined. Don’t over mix.
Generously spray pans with non-stick baking spray. Scoop batter into doughnut pans. Recipe makes 14 regular-sized donuts or 20 mini doughnuts. Depending on size, bake for 12-18 minutes in a 325°F oven or until a toothpick comes out clean.
Let cool 10 minutes and carefully remove doughnuts from pan while still warm.
