Instructions
Preheat oven to 400 degrees F. Line 12 muffin cups with muffin liners or spray with nonstick cooking spray.
In a large bowl whisk together flours, baking soda and salt
In the bowl of a food processor fitted with the metal blade, process buttermilk, sugar and orange marmalade until fairly smooth and the orange bits are finely ground. Scrape down the inside of the bowl and add eggs, butter, Cointreau, lemon juice; and grated lemon zest. Process until smooth.
Add this mixture to the dry ingredients and stir until just combined. Divide batter equally among prepared muffin cups. Bake until lightly browned and a little puffed, 16 to 18 minutes, rotating halfway through baking time. Cool muffins in muffin tin for 5 minutes, then transfer to wire rack to cool completely.
