Pour the protein shake, instant espresso powder, sugar substitute and guar gum into a small blender and blend until all ingredients have completely combined with each other. Pour the mixture into a Ninja Creami pint container.
Freeze on a level surface for 24 hours. Your freezer should be between 9 and -7 degrees Fahrenheit. To avoid getting a bump on the top of the frozen mixture, freeze with the lid off of the container.
Process the Ice Cream
After 24 hours, remove the pint container from the freezer.
Place the pint container into the outer bowl of the Ninja Creami and then process on "LITE ICE CREAM."
If the ice cream is dry or crumbly looking (like sand), pour in a tablespoon or two of unsweetened almond milk and then re-spin. If the ice cream looks like little balls of ice cream, respin without adding liquid. You may have to repeat this process a couple of times.
Dig a well down the center of the ice cream and pour in the chocolate chip pieces and sliced almonds. Process on mix-ins.
Remove the pint from the machine and enjoy!

Notes
Can I use brewed coffee or espresso instead of the instant espresso that the recipe calls for?I do not recommend using brewed coffee or espresso.Brewed coffee is much weaker in flavor and higher in water content than instant coffee or espresso powder.Since you are only using the powder, there is no additional water used in this recipe.Brewed coffee will result in less coffee flavor and an icier, and less creamy texture.
Why isn't there fudge in the recipe?Fudge does not stay together well when it's processed in the Ninja Creami.Instead of creating swirls of fudge, it just mixes in with the ice cream base.I even tried freezing the fudge before adding it during the mix-ins process and that does not help.Instead of fudge, this recipe uses chopped chocolate chips.
