All I did was add an extra square of baking chocolate. Easy! If making chocolate frosting use only 1 square of chocolate. If making the milk chocolate use 2 squares of chocolate. It makes for a more substantial chocolate confection.

Update:  I have no idea what happened, but feel the need to responsibly tell you what happened. I wanted to make the frosting (now in 2022). I doubled the recipe. I used chocolate chips (2 oz) instead of the baking chocolate.  The result was a very liquidy mixture - not a frosting!  So, I added 1/2 cup vanilla whey protein and put the mixture in the fridge and used it as frosting on top of cupcakes when it solidified a bit more.  It was delicious.  I can't see that using unsweetened baking chocolate vs chocolate chips would make that much difference?  Who knows, but this was my experience today.

Note:  For chocolate-sensitive people (allergies or migraines):  use 6 tbsp carob powder and 4 tbsp butter.  For those who don't have erythritol, use 6 packets sweetener (the kind for coffee). 

Milk Chocolate:
1/4 cup whole or skim milk powder (Hispanic section of Super Walmart or Publix)
3 tbsp whipping cream (or evaporated milk)
Liquid sweetener (sucralose or stevia) to equal 3/4 cup sugar
2 tbsp powdered erythritol, OR 6 packets sweetener (kind for coffee)
2 tbsp unsalted butter, melted (4 tbsp if using Carob powder)
1 tbsp water
1 tsp olive oil
½ tsp vanilla extract
2 oz (2 squares) unsweetened baking chocolate, OR 6 tbsp Carob powder

In blender, combine milk powder, carob powder (if using), whipping cream, liquid sweetener, erythritol, OR packets of sweetener, butter, water, olive oil and vanilla extract; blend.

In cereal bowl, place 2 squares baking chocolate (skip this step if using carob powder). Pour boiling water over chocolate and pour off when molten (test with a sharp, pointy knife).

Add to blender; blend until combined. Spread in two mini loaf pans, or whatever metal or glass pan you have on hand and freeze. Cuts easily right out of the freezer with a blunt knife into pieces for a nice chocolate fix and pick-me-upper.

If you like, add almonds or hazelnuts to the molten chocolate, before freezing.
