1Preheat your oven to 400°F (200°C). Grease a 12-cup muffin tin or line with paper liners.
In a large bowl, whisk together the cornmeal, all-purpose flour, sugar, baking powder, and salt.
In a separate bowl, beat the egg, then add the low-fat milk and olive oil. Mix well.
Pour the wet ingredients into the dry ingredients and stir until just combined. Do not overmix.
Fold in the shredded cheddar cheese and diced jalapeños until evenly distributed.
Divide the batter evenly among the prepared muffin cups, filling each about 2/3 full.
Bake for 15-18 minutes, or until the tops are golden and a toothpick inserted into the center comes out clean.
Allow the muffins to cool in the tin for 5 minutes, then transfer to a wire rack to cool completely.
Serve warm or at room temperature. Enjoy your Cheesy Jalapeño Corn Muffins!
