In a bowl, whisk together your dry pastry ingredients, up to and including the sweetener.
Add the butter chunks and use a fork or pastry cutter to "mash" the butter until the pieces are just slightly bigger than pea size (it's okay if there is the odd larger chunk). Alternatively you can grate your cold butter in.
Add 1/3 cup of the heavy cream and then using your hands try to form the dough into a rough ball. If it's still too dry, add a bit more cream to bring it together (you want to use as little cream as you can, the butter will help to moisten the dough). Try not to handle the dough too much.
Once you have a rough ball of dough, wrap it in saran wrap and place it in the fridge for 20-30min.
Remove the ball from the fridge and roll it out between two greased and very well "coconut floured" pieces of parchment paper. (Remember to sprinkle coconut flour on TOP of the dough as well before rolling out.
Fold each side of the dough inward (see photo), then turn the dough 90* and roll it out flat, squishing down the folded layers you just made. Then once again, fold each side inwards, turn 90* and roll it out flat. You want to repeat this 4-5 times to ensure layers of butter are spread throughout the dough. It will start off very rough looking but don't worry about that! Just push the rough edges in a bit and continue repeating the process until it looks more uniform. ( If at any time your dough feels warm, place it back in the fridge or freezer for a bit to get cold again. You don't want your butter to melt).
After you've rolled the dough out 4-5 times following step 7, fold it once more, Saran Wrap it and place it back in the fridge for another 30min.
Pre-heat your oven to 375*F.
While your dough is chilling, you can make your filling. Simply mix together the softened butter, sukrin brown sweeter and cinnamon in a small bowl until smooth.
Once your dough is done chilling, again roll it out flat between two greased and coconut floured pieces of parchment paper. Try to roll the dough into as even of a rectangle as possible that's about 1/4 inch thick (or just thick enough to easily lift and work with without tearing).
Spread your filling over the rectangle then roll it up from the longest side to the other long side. (Length to Length).
Pinch the edges of the dough together slightly then use a sharp knife or pizza cutter to slice 8-9 cinnamon rolls.
Place the cinnamon rolls cut-side up in a baking pan and bake them for 20-24min or until they are quite golden brown on the outside.
While they are baking, you can make the glaze by again, simply mixing the 3 ingredients together until smooth! Add more or less cream based on how thick you want your glaze/frosting.
