Combine warm water, yeast, and honey in a large bowl and let sit for 5-10 minutes until foamy.
Add olive oil, salt, and spelt flour to the yeast mixture and stir until well combined.
Gradually add bread flour, stirring gently until dough just comes together, being careful not to overmix.
Turn dough onto a lightly floured surface and knead gently for 5-6 minutes until smooth but still slightly soft.
Place in a greased bowl, cover, and let rise for 1 hour until doubled.
Gently shape into a loaf and place in a greased 9x5-inch loaf pan.
Cover and let rise for 40-45 minutes until dough rises about 1 inch above the pan.
Preheat oven to 375°F and bake for 30-35 minutes until golden brown and internal temperature reaches 190°F.
