See side bar for an explanation (click on post title if this is still the home page). This is a recipe for a small batch. Amounts can be altered somewhat.
Ingredients
4 cups Kix (or other cereal)
1/2 cup chocolate chips
1/4 cup nut butter of choice
1/8 cup butter or coconut oil (1/8 c = 2 Tbs)
1 cup powdered sugar*
*Powdered sugar can be made by putting granulated sugar in a high powered blender. This gives the advantage of being able to use coconut sugar or granulated monk fruit (it'll have erythritol in it too) as a healthier alternative to typical powdered sugar and cheaper than buying powdered monk fruit. You can also lower the sugar content by replacing 1/8 or so of the granulated sweetener with a flour (for gluten free, gluten free flour blend, tapioca, or possibly others). I haven't measured how much powdered sugar 1 cup of granulated sugar makes, but it's more than you started with. Leave the lid on the blender and give the fine powder a few moments to settle.
Directions
Put cereal in a mixing bowl (large enough to hold the cereal and later be able to mix it easily).
Measure the chocolate chips in a pyrex measuring cup (1 or 2 cup) if you've got one.
Add the nut butter and butter to chocolate chips and microwave 30-60 seconds.
Stir, microwave 30 seconds or less, repeat as needed until all melted.
Add chocolate mixture to cereal and stir until coated.
Put powdered sweetener in a ziplock gallon bag or a large clean paper bag, add coated cereal and shake until coated. (I think you could do this in another bowl if you don't have a bag--I wouldn't use the same bowl you mixed in or you'll end up coating the bowl as much the nuggets).
You can lay it out on a baking sheet and put in the fridge or freezer for a few minutes to "set up," but I think we've preferred just putting the whole bag in the freezer. Then you can get some nice clusters, and it's just plain easier.
