There could be a couple reasons why your cinnamon rolls aren’t rising:
 
1. You might have killed the yeast.
When you place your yeast in the milk make sure the milk isn’t too hot. The milk should be warm, but not hot. If it the milk too hot, there’s a chance you killed your yeast. Salt is also a yeast inhibiter. We add the salt in with the cinnamon roll dough ingredients only after we’ve let the yeast bloom. If you add the salt in with the milk and sugar, it will slow down or completely stop the yeast’s ability to rise.
 
2. Your kitchen might be too cold.
Yeast loves be warm and cozy and the cold is a yeast inhibitor—that’s why you can make cinnamon rolls the night before and pop them in the fridge to stop them from rising. So, if your kitchen is too chilly then your cinnamon rolls won’t want to rise, place them somewhere warm and make sure they’re covered so the dough doesn’t develop a dry skin on the outside, which could also stop your cinnamon rolls from rising properly.
 
My #1 trick for getting my cinnamon rolls to rise:
Like we said above, yeast loves the warmth, and your cinnamon roll dough will rise best when they’re in a warm place. So, I like to turn my oven on to as low as it will go, mine is 170 degrees Fahrenheit (most ovens will go as low as 200 degrees Fahrenheit). Let the oven preheat, then turn the oven off, and pop your covered dough inside to rise!

This might seem like a silly question, but after all the effort you put into making these chocolate pecan cinnamon rolls, I’d hate for a dull knife to mash your rolls and give you less than picture perfect cinnamon rolls.
 
Use a very sharp knife. You’ll want to use a super sharp knife; if it isn’t sharp it’ll just smash your rolls.
 
Use a serrated knife. If you have any doubts about the sharpness of your knife, a serrated knife a safer bet. Remember to be gentle and try not to smash the cinnamon rolls.
 
Use dental floss or thread. Dental floss or thread is a great way to get a nice clean cut without worrying about the dough sticking to the knife. I usually recommend using unflavored floss so you don’t get any lingering flavors. Though, the last time I made these I could only find cinnamon floss, but I figured that flavor would be all right, after all, these are cinnamon rolls!

You might notice in the picture above that the pecans are mixed straight into the filling with the butter, brown sugar, and cinnamon. That’s because that’s how I used to make these. But, I’ve realized it is much easier to spread the filling on with out the pecans in the filling and to just sprinkle the chopped pecans on afterwards. Just take my word on that.

Cream cheese icing is ideal for cinnamon rolls (in my opinion), the tanginess of the cream cheese just pairs beautifully with the other flavors we’ve got going on here! I like the cream cheese icing to be a little runnier than say a frosting I might use on a cake. This way the cream cheese icing just gets a little melty and floods into all the nooks and crannies of these cinnamon rolls.
 
To make this cream cheese icing, start by creaming together butter and cream cheese until smooth, then add in your vanilla, salt, and powdered sugar. If at first it seems like there is too much powdered sugar, keep going! It will mix in eventually!

While your dough will be quite sticky when you start kneading it, by the end it should just be a little tacky, and have a smooth and elastic feel to it.
 
If you do not knead your dough enough then the bread dough will not have a good structure and there’s a chance it will collapse on itself after it bakes.

I get it, these chocolate pecan cinnamon rolls take a couple hours to make start to finish and they are definitely best, warm and fresh! Luckily, you can make them ahead of time!
 
After you slice your cinnamon rolls and place the in their pan, cover them and pop them in the fridge for up to 24 hours. You can even freeze them and then defrost them in the fridge! Then, in the morning, place them somewhere warm and let them rise until they’ve doubled in size. Then, bake!

Cinnamon rolls always seem a little dry to me they day after, so warming them always makes them seem moist and gooey again. I like to microwave them for around 10-15 seconds, but every microwave is a little different so keep your eye on them!
