May have over-baked this a little, Baked for 1hr 10 as skewer came up wet. I did add 25g of chocolate nibs, which was a nice addition, but could not taste the peanut butter. Looks good, tastes ok. Not as flavoursome as the more basic recipe I tried yesterday. This loaf is more bread like than moist cake. I expected it to be much sweeter too, so if you like a less sweet loaf - go for this one!
