There's a quote at the top of the page where I found this recipe "Milk chocolate Morsels inside peanut butter squares. What could be better?" Well, I've found something better - plain chocolate chunks inside peanut butter squares!
I was directed to this recipe from one of the blogs on my reading list, but I've been looking at so many recently, I can't remember which one it was. Thank you anyway, whoever you are - these are quick and easy to make and really, really good!
All the recipes I found online for Chocolate Peanut Buddy Bars were identical to this one. All I did differently was use chopped plain chocolate bars - a mixture of 74% and 85% cocoa solids - and cook it in a 12 x 8" tin, slightly smaller than specified, but all I had - and a good decision as it turned out, as the bars were quite shallow, even in a smaller tin. I also put the tray back in the switched-off oven for 5 minutes to melt the chocolate topping completely.
Here's the ingredients 'translated' to metric weights:
250g peanut butter - I used smooth.
85g softened butter
280g caster sugar
3 large eggs
1 teaspoon vanilla extract
125g plain flour
350g chopped plain chocolate
There's no way to get 36 bars out of the tray though! I got 20 squares of a reasonable size with a 5 x 4 cut. If you wanted bar shapes a 6 x 3 cut would be about right.
