Mix protein powder and coconut flour in a bowl until well combined. Set aside.
Heat a small pan, low-medium and add almond butter, coconut oil and maple syrup. Stir until the almond butter is melted and the mixture becomes smooth. Pour melted mixture into dry mixture and stir until fully combined.
Pour the mixture into a container lined with parchment paper, spread evenly and press it down firmly.
Place container into the freezer for about 30 minutes until hardened.
Remove container from freezer and use the parchment paper to lift the fudge. Cut with a sharp knife into bite sizes of your choice. Enjoy.
