Add all of the protein bar ingredients to a bowl and mix well. Transfer to a parchment-lined loaf pan and press the dough in until you form an even layer.
Blend together the cream ingredients until you get a smooth texture. Pour on top of the bars and use a spatula to create an even layer.
Place the bars in the freezer for 2-3 hours until the cream hardens. Then remove from the freezer, add cinnamon on top, slice the bars, and enjoy!
Store in the fridge.
