Novelty I remembered something I made up sometime ago, in the last Bootcamp, which I hadn't put on the recipe thread. It might be right up your street:
1 dessert spoon peanut butter
2 dessert spoons Total full fat yoghurt
1/4 teaspoon vanilla bean extract
Mix the lot together then shove in your gob!
It doesn't sound like much, but it's incredibly rich and the texture means it's incredibly satisfying.
Then I did some counting/calculating:
2 level teaspoons peanut butter (mine is Whole Earth smooth, 9.9g carbs per 100g)
4 level teaspoons yoghurt (full fat Total, 3.8g carbs per 100g)
If you just mix this together, this will be 3.5g carbs. It makes a small but very rich treaty snack.
You may like to add vanilla - I used vanilla bean extract. This contains sugar (I've run out of the Waitrose one which is sugar-free). There is no nutritional info on the pack, so I have assumed the worst, and that it's the equivalent of adding sugar. You only need 1/4 teaspoon, though, which will add another 1g of carbs.
You could freeze it, I suppose, and I was also wondering if, rolled into balls, you could make some lovely after dinner 'chocolates' - either rolling them in cocoa or coating in melted dark chocolate.
You can also buy a chocolate extract from Waitrose/Lakeland which might be lovely in this too!
