Put all of the ingredients into the Ninja Creami pint container.
Give it all a really good mix to combine everything.
Put the lid on the tub and freeze for 12 hours (not the usual 24, like most recipes).
Remove the lid and put the frozen pint tub into the outer bowl and put on the outer bowl lid. Put into the Ninja Creami machine and set to the Lite Ice Cream setting and spin.This one spin should be sufficient to achieve a fudgy texture. It may look crumbly, but trust us - it is ready to serve.
Notes
Remember - this Ninja Creami recipe only needs to be frozen for 12 hours.
One of the biggest secrets to getting a really creamy results is making sure your base is fully smooth before freezing. Any dry pockets of cocoa or protein powder can affect the final texture.
Taste the mixture before freezing. Different protein powders vary hugely in sweetness, so you may want to add a little more maple syrup depending on the brand you use.
Let the pint sit at room temperature for around 5 to 10 minutes before spinning if your freezer runs especially cold. This can help the machine process the pint more evenly.
For the thickest fudge-like texture, serve it straight after spinning. If you refreeze leftovers, the texture will firm up and may need to be processed again before serving.
