I follow this recipe to make biscotti and replace 1 egg with 50 gms of butter. So I end up adding 2 eggs and 50 gms of butter.It is always incredibly yummy but I have 2 issues and would be great if I could get some tips or help:
- I never get uniform sized/shaped slices like in the picture on the website. They are very small on the ends and very long in the middle even though I try to make a very uniform looking logs before baking.
- Some of the biscotti slices are very crumbly and break when I slice them. I do use a very good serrated knife to slice the log.

Chill this or any cookie dough once finished mixing and before baking. Make your biscotti dough into perfect rectangle logs right to the edge of your pan, with even height and width right across. Use a ruler if you have to. I suspect you have a higher height in the middle - that dough will need to go somewhere when heated, and that's sideways (creating your longer middle baked width).
Once you have these perfectly formed rectangles of dough, chill in the fridge for an hour at least. This will really help keep it's shape and reduce any uneven spreading during bake. You could also try slightly increasing your first-bake temp 10-15 degrees as this will help quick set the exterior of the biscotti logs. The only other thing I may mention is the recipe - perhaps you can just slightly scale back the baking powder to help reduce the spread of the dough during baking.
Once baked just to set (depends on size), pull from the oven and let cool just slightly. While still warm to the touch, start slicing your cookies to a consistent, even desired width - I really recommend using an electric knife if you have one to make the work a lot easier for yourself. If you don't have one, just work quickly with your best serrated knife. Doing this while still warm will definitely help with reducing breakage and crumbs.
