I can't stand bitter (largely the reason I hate beer), so probably should have considered that before buying them lol.
Anyway, I made the bars on the weekend. My verdict:
- Texture is brilliant, very moist / cake-like. Maintains the texture for several days.
- Very mild taste (and I used chocolate flavoured protein). Still tastes nice, but I'd prefer something a little sweeter. Might add a bit of splenda next time.
- Did not like the icing at all, could barely taste the vanilla. Won't bother with icing next time, will just make the bars (they taste better without IMO).
- Did not like the vanilla bean paste. Cost $10, I used almost the entire jar and still couldn't taste or smell it. Next time will just use a bit of imitation vanilla essence in the bar.
- I used some of the cacao nibs in the batter. Couldn't taste any bitterness, so will add even more next time (I have a lot to get through lol).
All in all, it is quite a good recipe. Not as sweet as I imagined, but very impressed with the texture.
Will make a few tweaks next time and see how it goes!
