Baking – Too much sugar – HELP

baking

I'm making a cinnamon raisin bread. The recipe calls for 5 3/4 cups of flour and 4 tsp of sugar in the first part. Later on it calls for 3/4 cups of sugar mixed with cinnamon. I was working the recipe from my computer screen and somehow missed the first sugar in the ingredients and added the 3/4 cups to the dough. I didn't realize the mistake until it was already proofing. I did add some extra water to the knead, but not enough. The dough is barely rising after 2 hours. What can I expect the results to be? Thank you in advance for any help.

It will not go well, as I think you already have guessed.

The reason for this is that concentrations of sugar over about 4-5% are inhibitory to yeast growth in bread making. You need the yeast growth to make the bubbles of carbon dioxide that cause the bread to rise.

The only reference I could find for this is from Food and Feed Technology p. 729.

...sugar concentrations ~4% produce apparent inhibition...

The book then goes on to say:

Consequently sweet yeast raised breads (15-20% sugar) contain very high yeast concentrations

Your concentration of sugar is about 13% (0.75/5.75), well above where it needs to be for the bread to rise with regular amounts of yeast.

I suspect that you won't be able to resurrect it by adding extra yeast at this point, it would be over-kneaded and probably won't rise all that well, or will rise and then collapse during baking. Your only sure way is to start again and follow the recipe.
