Healthy Low Fat Banana Cake with Peanut Butter Frosting
Low fat banana cake, a lighter from scratch fresh banana cake with a thin layer of sweet peanut butter frosting. This banana cake is an old family favorite recipe that I’ve tinkered with – decreasing the sugar and fat – to make it Weight Watchers friendly. I also cut the frosting recipe in half, spreading the cake with a thinner layer of sweet peanut butter frosting – so you get all the lusciousness; just less of it.
If you don’t like peanut butter frosting, feel free to substitute a thin layer of your favorite icing – vanilla, chocolate, cream cheese, and coconut – would all be delicious.
The original recipe is from one of my favorite baking books, Sylvia’s Cakes and Breads: Famous Recipes from a Small Maine Kitchen
Enjoy!

You basically just have to utter the words “peanut butter” and I’m interested, but this cake really does sound delicious! I love bananas spread with peanut butter, so I can only imagine how amazing this tastes.

I think you could make it in a crockpot. Hope so! Love your recipies everything Ive made from your web site is delicious. LOVE the Chocolate pudding cake taste like brownies!

Hi – Just wanted to share… Made this delicious cake earlier this week – it actually seems to be improving with age – the bananas keep it really moist. It’s a real winner – and has gone in my regular recipe files. Particularly enjoyed the light, but very tasty, layer of icing – made it feel indulgent. The little 2×2 squares are surprisingly generous for a LFLS dessert – I love that they’re actually taller than square! Just fo glamourize it up – I had a little bit of dark chocolate ganache in the fridge – warmed it in a zip bag and piped lines about an inch apart and them “feathered” them – napoleon style. Only used 2 T of the ganache, so no critical change in calories – and made it beautiful enough for guests! Thanks again – definitely going to look at your recipes time and again when I’m “browsing”.

Carol,
Thanks for taking the time to leave such a thoughtful comment. I very much appreciate it. Love what you did with the chocolate ganache to “dress up” this dessert for guests. I must remember that the next time I make an iced cake, since I rarely remember to fancy things up 🙂

This was wonderful! I even lowered the fat and calorie content more by substiting applesauce and FF Greek yogurt for the oil, using egg substitute and skim milk soured with lemon juice.

Glad you liked it Lauren!

There’s a low fat apple cake recipe on the web that doesn’t use any oil and only 1/3 cup sugar. I’m going to make that with bananas. It’s amazing with apples and I’ve made it 3 X’s this past week. Yes, it’s that good. 116 calories/slice

Would love the apple cake recipe!
