Chocolate Chip Muffins

Instructions:
Step 1: Preheat your oven to 375°F (190°C). Line a 12-cup muffin pan with paper liners or lightly grease it.
Step 2: In a large bowl, whisk together the flour, granulated sugar, brown sugar, baking powder, and salt.
Step 3: In another bowl, whisk together the milk, oil, eggs, and vanilla extract until well combined.
Step 4: Pour the wet ingredients into the dry ingredients and mix just until combined. Do not overmix.
Step 5: Gently fold in the chocolate chips.
Step 6: Divide the batter evenly into the prepared muffin cups, filling each about 3/4 full. Sprinkle a few extra chocolate chips and coarse sugar on top if desired.
Step 7: Bake for 18-22 minutes or until a toothpick inserted into the center comes out clean.
Step 8: Let the muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.

Storage and Reheating Tips:
Store muffins in an airtight container at room temperature for up to 3 days or in the fridge for up to a week. To freeze, wrap each muffin in plastic wrap and place in a freezer-safe bag for up to 3 months. Reheat in the microwave for 15-20 seconds or in a warm oven until heated through.
