In a large bowl, add all-purpose flour, yeast, cocoa, caraway seeds, and blend everything well.
In a pan, add butter, sugar, salt, water, and molasses, let it all heat up and stir it from time to time. After everything mixes well, add this warm mixture to the dry flour mixture. Take an electric beater and beat the flour mixture for a minute or two at low speed and then at high speed for three minutes.
Now, make a soft dough with your hands and put it on a floured surface. Knead it well and let it rest for 20 minutes. After the given time, punch the dough and divide it into two halves. Give it the shape of a round loaf.
Now, grease an 8-inch pie plate and transfer the loaf to the plate. Then brush the loaf with butter or cooking oil and slash the loaf 3-4 times from the top.
Bake it in the oven for almost 30 minutes at 400 degrees F until it rises. After the given time, let it rest and cool down on a wire rack. Cut it into two halves as the dark rye bread is ready.
