Combine yeast, honey, butter, salt, warm water, instant coffee, and cocoa powder in a mixing bowl. Gradually beat in 3 cups flour. Mix with your hands until ingredients form into a ball; transfer it to a floured work surface. Knead in additional 1/2 cup of flour if the dough is too sticky to work with. Knead the dough until it is smooth and elastic, about 15 minutes.
Place the dough in an oiled bowl and cover it with plastic wrap and a kitchen towel. Let rise in a warm place until doubled in bulk, about 1 hour. Deflate the dough and turn it out onto a lightly floured surface. Flatten the dough into a rectangle, pressing down with your hands to pop any air bubbles. Fold the dough into thirds, rolling it slightly under your palms to form a loaf, and pinch the seam to seal. Shape the dough into a freeform loaf and place onto a parchment-lined baking sheet.
Cover the dough with a floured kitchen towel and allow it to rise again until doubled, about 30 minutes.
Preheat oven to 400 degrees F (200 degrees C).
Remove the towel. Use a serrated knife to score the loaf, cutting three slashes on the top or as desired.
Bake in the preheated oven until the top is golden brown and the bottom of the loaf sounds hollow when tapped, 20 to 30 minutes. Remove the bread from the loaf pan and cool on a wire rack.
