How to cook
Mix the sifted flour, baking powder, baking soda, sugar and cocoa in a bowl.
Separately, beat the egg, milk and oil/butter. Carefully add the dry mixture to them in lots, while beating nonstop.
Next, add the orange zest, essence/liqueur and crumbled chocolate.
Distribute the mixture into prepared and greased muffin forms, up to about 2/3 of the way up.
Put the Dark Chocolate Muffins with Orange Zest to bake in a preheated 392°F (200 °C) oven about 20-25 min.
The products listed yield about 12 muffins.
