WHY YOU’LL LOVE THESE BANANA BLONDIES

- Topped with SINFUL cinnamon brown butter frosting!
- Great to make any time of year.

For the blondies:
- Bananas – The riper, the better!
- Greek yogurt – Adds such a moist texture.
- Canola oil
- Brown sugar – I used Swerve Brown Sugar.
- Milk – I used unsweetened almond milk, but any milk works.
- Baking essentials – We’ll use vanilla extract, baking powder, baking soda, and salt.
- Flour – I used all-purpose flour. Using almond or oat flour will change the flavor/texture, but they would still work. If you wish to make gluten-free blondies, try Bob Red Mill’s 1:1 Gluten-Free Flour.
- Protein powder – I used PEScience Vanilla. Keep in mind that not all protein powders bake the same, so if you use a different kind, use a similar whey + casein blend, not just a whey protein powder. Code LaurenFitFoodie will save you 15% on PEScience products.
For the frosting:
- Cream cheese – I used 1/3 reduced fat. Full fat, fat-free or Neufchatel cream cheese work, too.
- Unsalted butter – We’ll brown this in a pan for incredible flavor!
- Vanilla extract
- Confectioners sugar – I used Swerve Confectioners Sugar.
HOW TO MAKE BANANA BLONDIES
To make the blondies:
- Preheat the oven to 325°F. Line a 8×8-inch baking pan with parchment paper or spray with nonstick cooking spray.
- In a medium-sized bowl, add the flour, protein powder, baking powder, baking soda, and salt. Stir to combine.
- In a large bowl, add the bananas and mash them well. Then, add the yogurt, oil, brown sugar, milk, and vanilla. Combine with a hand or stand mixer.
- Pour the batter into the prepared dish. Bake for 25-30 minutes or until a toothpick inserted in the center comes out mostly clean. We want it to be slightly gooey for a more moist texture!
- Let blondies cool to room temperature before adding frosting.
For the frosting:
While the blondies are baking, make the cinnamon brown butter frosting:
- Start by melting the butter in a saucepan over medium heat, stirring occasionally. Once melted, the butter will begin to foam. Keep stirring occasionally. After 5-8 minutes, the butter will begin browning. You’ll notice lightly browned specks begin to form at the bottom of the pan and it will have a nutty aroma. Once browned, remove from heat and pour into a heat-proof bowl. Refrigerate until solid.
- In a large bowl, beat cream cheese and butter together on high speed using a handheld or stand mixer fitted with a paddle or whisk attachment.
- Add cinnamon, salt, vanilla and confectioners sugar. Beat on low speed for 1 minute or until everything is combined.
- Once blondies have cooled, evenly cover the top with frosting. Cover and store in the fridge until ready to serve. They’ll taste best if you let them sit overnight!
Frequently Asked Questions
Because it creates such incredible flavor! Browning the butter creates a warm, nutty flavor that tastes incredible with these banana blondies. Trust me, you won’t regret it!
Yes, you can. But freeze them without the frosting. Let blondies cool to room temperature and then cut into bars. Wrap the bars individually in parchment paper, wax paper, or aluminum foil. Then, store in a Ziploc bag. To prevent freezer burn, make sure to remove as much air as possible. If stored properly, bars will stay fresh for 6 months. Frost after you defrost and are ready to eat.
Absolutely. Use whatever you like. I think chocolate, vanilla, or plain cream cheese frosting would taste great.

Do you know if you could substitute applesauce for the oil? Seems like it would be the perfect fit and reduce the macros even more.
The blondies will be more cakey and won’t be as moist if you sub with applesauce, kind of more like a banana cake, but it will still be good– especially with the brown butter frosting!
I made this for my family this weekend and everyone loved it! The frosting took a little bit of time because I had to wait for the brown butter to cool down. But everything turned out great! Love your recipes. Please post more.
