Recipe Comments & Reviews

This recipe was fairly easy and had great flavor. I used three bananas and it was packed with banana flavor. It was moist and I will make it again.
Super simple, no-fail recipe that is fabulous!
I'm not a big fan of the traditional "banana bread" - but this recipe was delightful. SUPER easy, very moist, low calorie, winner.

Cool thing was I actually FROZE my over ripe bananas, then took them out of the freezer for this recipe. Worked like a charm. Tip: peel the banana right away when you get them out of the freezer and place in a strainer over a bowl. As they thaw there some banana syrup/juice that drips out which might have made the bars too wet.
HEY! Check out my teenage blog with some tasty banana recipes (all baked)! View at
I used ground nuts instead of the unsweetened cocoa and frosted them....excellent!
Best banana bars we ever had...and so easy to make.
Made this for a family BBQ and hit was a huge hit! East to make and super moist.
bananas should be very ripe ie; black. These came out very moist and my family devoured them!!

Cranberry Swirl Sweet Rolls
November 24, 2015 by Mallory

I always have him make twice the amount needed because I love having leftovers. This year, I decided that rather than serving it alongside leftover turkey and mashed potatoes, I was going to try something new. We still have guests lingering the day after Thanksgiving, so what better way to ease the turkey “hangover” than with homemade sweet rolls for breakfast? More ...
