Preheat your oven to 400° F. Place cupcake liners into a standard sized (12 cup) muffin tin. Set aside.
Fill the 12 muffin cup liners with the batter, dividing evenly. Use all the batter (mine were filled almost to top). Bake muffins at 400° F. for 20-22 minutes . When done, you should be able to stick a toothpick into the middle of the muffin and it will come out clean. The tops of the muffins will be light golden brown in color. Transfer muffins out of muffin tin and onto a wire rack to cool. I place a piece of aluminum foil (or parchment paper) UNDER the rack to catch any icing drips when glazing the muffins later. Let the muffins cool to room temperature. While muffins cool, prepare lemon glaze.
Stir powdered sugar, lemon juice and lemon zest in a small bowl until fully blended, and lumps are gone. You want a good consistency to drizzle over the top of each muffin, but not too thin where it runs all over. If you want glaze thicker, add a bit more powdered sugar. If you want glaze thinner, add a tiny bit more lemon juice (or water). Once muffins are at room temperature, drizzle lemon glaze on top of each one (the foil under the rack will catch wayward drips, which makes cleanup easy). Let the glaze firm up for several minutes, then muffins are ready to eat! ENJOY!
