Slice the jalapeno and add it along with the shredded cheese. Mix using a wooden spoon. Carefully remove the cast iron skillet from the oven.
Step 4
Grease it with the oil and add the batter. Spread the batter using an offset spatula. Return the cast iron skillet to the oven.
Step 5
Bake for 15-20 minutes or until the top is golden brown and an inserted toothpick comes out dry. Remove from the oven and let it cool slightly before slicing.
Step 6
Cut the loaf into 12 squares. Serve warm as a side dish. Store leftovers in an airtight container.
