I originally found this recipe here at MILK & COOKIES Blog I was slightly confused by the metric measurements (she's from Australia) so I searched and found this recipe on RecipeZaar which is the same recipe only converted.
Jimmy said these tasted just like an orange stick but in muffin form. We quite liked them. Cheerio matey! Isn't that a lovely photo. Mine didn't quite look as lovely, but were still tasty.
Orange Dark chocolate Muffins
1 3/4 cups all-purpose flour
1 1/2 teaspoons baking powder
3/4 cup caster sugar
1 tablespoon orange zest
1 cup dark chocolate, roughly chopped (I used Semi-Sweet Chocolate Chips)
1 cup plain yogurt (no gelatine) or sour cream **
2 ounces unsalted butter, softened (which is 1/2 cube or 1/4 cup)
2 tablespoons orange juice
Preheat oven to 350°F.
Place the flour, baking powder, sugar, orange zest, and chocolate in a large bowl and mix to combine.
In another smaller bowl, combine the yogurt, butter, eggs and orange juice until well blended.
Add the wet mixture to the dry mixture and mix until just combined.
Spoon the batter carefully into the greased muffin tin.
Bake for 35-40 minutes or until the tops are golden and cooked when tested with a skewer. (I baked mine for about 28 minutes)
Remove from oven and cool for 5 minutes. They are ready to serve straight away.
** I used about 3/4 cup sour cream and 1/4 cup yogurt because I didn't have yogurt without pectin.
