Preheat your oven to 375°F. Grease a mini muffin tin.
In a large bowl, whisk together the cornmeal, flour, baking powder, baking soda, and salt.
1 cup (156 g) Cornmeal, 1 ¾ cup (210 g) all purpose flour, 2 tsp baking powder, ¼ tsp baking soda, 1 tsp salt
In a separate bowl, whisk together the honey, milk, egg, melted butter, and oil until smooth.
½ cup (168 g) honey, 1 ¼ cup whole milk, ¼ cup (57 g) butter, ¼ cup (50 g) neutral oil, 1 large egg
Pour the wet ingredients into the dry ingredients. Stir gently until just combined—don’t overmix.
Gently fold in the diced jalapeño.
½ cup finely diced jalapeño
Spoon the batter into the mini muffin tin, filling each cup about 1/2 full. Do not overfill. Add jalapeño rounds to the tops if desired.
Bake for 10 minutes, or until a toothpick inserted in the center comes out clean. Let cool 10 minutes in the pan, then remove from pan and cool on a wire rack.
