In a large mixing bowl, combine flour, sugar, salt, and yeast. Whisk together until blended. Slowly pour in warm water and olive oil. Stir until a shaggy dough forms.

Turn the dough out onto a floured surface and knead for about 5 minutes until smooth and elastic.

Place the kneaded dough in a greased bowl, cover, and let rise in a warm spot for about 1 hour until doubled in size.

Gently punch down the risen dough, add cheddar cheese and jalapeños, and fold in carefully.

Shape the dough into a log and place it in a greased loaf pan. Cover with a cloth and let rise for 30 minutes.

Preheat oven to 375°F. Bake the loaf for 25-30 minutes until golden brown and sounds hollow.

Cool the bread in the pan for 10 minutes, then transfer to a wire rack to cool completely for at least 20 minutes before slicing.
