Step 1. Add dried cranberries, water, and sweetener to a medium-sized microwave-safe bowl and microwave for 4 minutes.  Give it a stir and then set aside to plump.

Step 2.  In a large bowl, sprinkle yeast over warm water (like bath water), then sprinkle the sugar over the yeast. Cover, and wait ten minutes for the yeast to ferment and become frothy/bubbly over the water and sugar.

Step 3.  Blend vital wheat gluten, almond flour, coconut flour, and flaxseed meal in a medium bowl.

Step 4.  Use a stand mixer with a paddle attachment or a wooden spoon to stir 1 1/2 cups of the flour mixture into the yeast mixture.

Step 5.  Stir for 1 minute.

Step 6.  Let stand for 10 minutes.

Step 7.  Mix the salt and baking powder into the flour mixture.

Step 8.  Stir the vinegar into the melted butter.

Step 9.  Stir the butter mixture into the dough until the liquid is absorbed.

Step 10.  Slowly mix in the remaining flour mixture. It will be very dry.

Step 11.  Add the cranberries and remaining liquid to the dough and use your hands to blend them into the dough.

Step 12.  Cover the dough and let it rest for 10 minutes.

Step 13.  Either use a stand mixer with a dough hook attachment or turn the dough out onto a lightly almond floured surface and knead by hand for 10 minutes.  If the dough is too dry to hold together, then you can add a little more water until it is kneadable.

Step 14.  Grease a large bowl with butter.  Form the dough into a ball and add it to the greased bowl. Flip it so that it is buttered on both sides.  Cover the bowl with plastic wrap.

Step 15.  Move the oven racks to the middle and bottom positions.  Put a casserole pan on the lower rack.  Fill the pan with boiling water and add the bread dough to the middle rack of the oven.  Quickly close the oven door.  As long as you open and close the oven quickly, you can use this warm oven for both bread rises.

Step 16.  Allow to rise until it is about 1/4 larger (1-2 hours).  This bread is not going to rise a whole lot.  That's ok.

Step 17. Roll the dough out into a rectangle that is 8 inches by 12 inches.

Step 18.  Mix together the filling of melted butter, brown sugar substitute, and cinnamon.  Spread the mixture over the entire surface of the dough from edge to edge.  Tightly roll the dough so that is 8 inches long by 4 inches wide.  Place the dough into a greased 8 1/2 by 4 1/2 inch loaf pan, with the seam on the bottom.

Step 19.  Let rise for 40 minutes in the warm oven.  It will only rise a small amount.

Step 20.  Preheat oven to 350 degrees F.  Brush the top of the loaf with melted butter.

Step 21.  Bake for 50-55 minutes until nicely browned. Use an instant-read thermometer to check that the insides are between 190-200 degrees F.  If it's not up to temp, then continue baking until it is.

Step 22.  Cool the bread in the pan for 10 minutes.

Step 23.  Slide the loaf out onto a wire drying rack and cool completely before cutting.
