Chocolate Orange Swirl Muffin

I am in the process of organising some of my past recipes and I have chosen those really yummy ones to share with you all.

This chocolate orange swirl muffin is one of my all time favourite. It is quick and easy to make and yet truly delicious.



Ingredients
1 1/2 cups plain flour
2 tsp baking powder
90g sugar
1/4 teaspoon salt
1 egg
125 ml buttermilk
125 ml orange juice
60g unsalted butter, melted
60ml corn oil
1 teaspoon vanilla essence
grated orange zest of 1 orange
2 tablespoons unsweetened cocoa powder

Method:
1. Preheat the oven to 190C. Line muffin pan with paper cups.
2. In a medium mixing bowl, sift together the flour, sugar, baking powder and salt.
3. In a separate mixing bowl, whisk together the egg, buttermilk, orange juice, melted butter and corn oil, vanilla essence and grated orange zest.
4. Pour the egg mixture into the bowl of dry ingredients. With a fork or a whisk, stir them together just until they are combined, forming a uniformly moist batter. Do not over stir; it is OK if a few streaks of flour remain.
5. Pour half the batter into another bowl. Stir all of the cocoa powder into one bowl of batter.
6. A tablespoonful at a time, alternating spoonfuls between the two bowls to produce a swirled effect.
7. Fill each muffin cup about 80% full. Bake in the oven for 12 minutes then rotate the muffin pan so the muffins at the back of the oven are now toward the front, for more even baking. Close the oven and continue baking till a cake tester inserted into the center of a muffin comes out clean, about another 10 to 15 minutes more.

Notes:
To make buttermilk:
I add 1.5 tsp of lemon juice into a cup then top up with milk until it is 125ml. Leave aside for 15 - 30 minutes before using it.
