In a small saucepan, over medium heat, cook raspberries with the swerve sugar substitute, cornstarch, water, and lemon juice. Stir the mixture to help break open the berries. Cook for about 5 minutes or until the mixture starts to thicken slightly. Let the raspberry sauce cool.
Make the Ice Cream Mixture
Pour the protein shake, vanilla bean paste, and guar gum into a small blender and blend until all ingredients have completely combined. 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, pour in a tablespoon or two of unsweetened almond milk and then re-spin. Only re-spin once. The raspberry sauce that is added as a mix-in has a lot of liquid in it and if you re-spin more than once, the ice cream will be very soft.
Dig a well down the center of the ice cream and pour in the chopped cashews and raspberry sauce that you made. Process on mix-ins.
Remove the pint from the machine and enjoy!
Notes
What is baseball nut ice cream?Baseball nut ice cream is a vanilla ice cream based that has pieces of cashews and ribbons of sweet raspberry sauce throughout. The Ninja Creami does not make good ribbons or swirls. So, in this recipe, I have added a raspberry sauce to the recipe. You end up with a delicious vanilla ice cream with bits and pieces of raspberries and cashews throughout!
Can you skip the step for cooking the raspberry sauce?You can. But, the ice cream won't be nearly as good. Cooking the raspberries with the sugar substitute helps bring out the flavor in the raspberries. The raspberry flavor becomes more intense and adds much more flavor to the ice cream.
