Banana Bread Brownies with Peanut Butter Cream Cheese Frosting

Banana Bread Blondies with Peanut Butter Cream Cheese Frosting

What do you have planned for Mother’s Day this year? Are you brunching with your family? Or making breakfast in bed for your Mom? We are having brunch at my sister in law’s and last year on Mother’s Day was the first time I had a banana bread brownie. She made delicious ones topped with a creamy frosting. They were so good and I have thought of them many times since last year.

Banana Bread Brownies with Peanut Butter Cream Cheese Frosting

I am not sure what the frosting was on the original banana bread I had at my sister in law’s, but since I love to eat bananas and peanut butter as a healthy afternoon snack, I thought the combination would work perfectly. These brownies aren’t quite as healthy, ah-hem, or not really healthy at all, but I did lighten them slightly by using an all natural sweetener substitute. Feel free to use regular sugar if you’d like! They do taste just like my favorite snack though, but so much more delicious! The brownie is dense and chewy and just slightly sweet, and the frosting is rich and creamy and adds a touch of sweetness, but with salty undertones from the peanut butter. These brownies stay so moist from the tangy sour cream and the slight tang from the cream cheese really plays off that nicely.

Since these are reminiscent of banana bread, they would go great with your Mother’s Day Brunch Menu! I prefer these served cold straight from the fridge, so they pair perfectly with a hot cup of coffee. I really hope you try these Banana Bread Brownies with Peanut Butter Cream Cheese Frosting. You certainly won’t be sorry!

  3. Add in the mashed bananas and vanilla and mix again, 1-2 minutes.
  4. Add your flour, baking soda, and salt and beat again for another minute or until mixture is smooth, with some small banana chunks remaining.
  5. Pour batter into your greased pan and bake for 20 minutes, or until sides start to brown. Remove from oven and let cool completely.

  7. In the bowl of a stand mixer fitted with the paddle attachment, cream together cream cheese and peanut butter until very smooth.
  8. Add 2 tsp. of milk and beat to incorporate. Add more milk if mixture still seems too thick to move around freely in the bowl.
