In a large mixing bowl, combine cake mix, pudding mix, eggs, coconut milk, oil, and yellow food coloring; beat with an electric mixer on low for 30 seconds. Scrape down the side of bowl. Beat on medium for 2 minutes more. Spoon the batter into the prepared muffin cups, filling each about 3/4 of the way full. Bake for 15 to 20 minutes or until a toothpick inserted near centers comes out clean. Cool cupcakes in muffin cups on a wire rack for 5 minutes. Remove cupcakes from muffin cups and cool completely on wire rack.
