(adapted from pepper.ph)
1/2 cup (1 stick) butter, at room temperature, plus more for muffin tin1 1/2 cups all purpose flour
1 teaspoon baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
1 cup granulated sugar
2 large eggs
1/4 cup milk
1/4 cup calamansi juice
Preheat oven to 350F. Using a pastry brush, coat muffin pan with butter. This recipe makes 8 to 10 muffins depending on the size of your pan.
Sift together flour, baking powder, baking soda and salt.
In a bowl, beat the butter with an electric mixer on medium speed until light and creamy. Add in the sugar and continue to mix. Add eggs one at a time, beating well after each addition.
Combine calamansi juice and the milk- it will look curdled, but rest assured that it's alright.
With the mixer on low speed, add the flour mixture in three batches, alternating with two additions of the calamansi mixture.
Spoon the batter into prepared muffin pan, filling each cup about 3/4 full. Bake until a toothpick inserted in center comes out clean, 20 to 25 minutes. Serve warm.
