Preheat your oven to 350°F (175°C). Line a cupcake pan with cupcake liners.
In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
In a large mixing bowl, combine the sugar and vegetable oil. Mix until well combined.
Add the egg and egg whites, one at a time, mixing well after each addition.
Stir in the almond extract.
Gradually add the dry ingredients to the wet mixture, alternating with the milk. Begin and end with the dry ingredients, mixing just until combined.
Gently fold in the chopped maraschino cherries and the maraschino cherry juice until evenly distributed throughout the batter.
Spoon the batter into the prepared cupcake liners, filling each about 2/3 full.
Bake in the preheated oven for 18-22 minutes, or until a toothpick inserted into the center of a cupcake comes out clean.
Allow the cupcakes to cool in the pan for about 5 minutes, then transfer them to a wire rack to cool completely.
