Frosted Banana Bread Cookies are super soft, chewy and topped with a delicious brown sugar frosting. This easy cookie recipe tastes just like banana bread!
You can make these old fashioned banana cookies with only 2 bananas. So, if you’re tired of banana bread, this easy recipe is for you!
I inherited over two bags filled with just about every recipe that my grandmother had ever collected or created. And she collected tons — some went back to the 1950’s and earlier.
For almost an entire weekend, I just sat and sifted through just about every scrap of paper in the collection over and over again. I was definitely in my happy place!
If you’re a recipe collector, or you love old family recipes, you’ll understand.
And somewhere in that gigantic pile, along with The BEST Chocolate Chip Oatmeal Cookies, Meringue Chocolate Chip Cookies and No Bake Chocolate Oatmeal Cookies, I found the recipe for these incredibly delicious frosted banana bread cookies.
The original name for them was just written as banana cookies, but they really do taste exactly like banana bread. So, that’s what I’m calling them.
How to Make Banana Cookies with Brown Sugar Frosting
The thing about so many old family recipes is that the instructions aren’t always that clear. Know what I mean?
Luckily, this cookie recipe was pretty clear, and I only changed a couple of things. I used butter instead of shortening, and I added cinnamon.
It’s an easy recipe. You start out by creaming butter and brown sugar, and you gradually add the remaining ingredients.
The cookie dough is sticky and a little bit messy. You can either use a spoon to drop the dough onto the cookie sheets, or you can pipe the dough using a piping bag or zip top plastic bag.
A reader shared this tip with me, so I’m passing it on.
You’ll want to line your cookie sheets with foil, parchment paper or baking mats for easier clean up.
The cookies are done when the edges are slightly brown and firm. They take about 8 to 10 minutes to bake, depending on your oven.
And after they cool, it’s time to frost them!
The boiled brown sugar frosting is super easy to make, and it’s seriously good. It’s just butter, brown sugar, vanilla and cream mixed with powdered sugar.
The original recipe didn’t even specify how much powdered sugar to add. It just said to add enough to make the frosting spreadable. So I added about a half of a cup, and this worked perfectly!
If you want thinner or thicker frosting, you can just adjust the amount of powdered sugar.
Note — the frosting is thin but thickens as it cools. Allow a few minutes for the frosting to cool down, and then spoon it onto the cookies.
Actually, the cookies are perfectly delicious without the frosting, so you could even skip that part. But, I really hope you don’t, because the cookies are AhMAYzing with it!
This recipe make about 50 of these little banana bread cookies, which seems like a lot. But trust me, it’s not. These babies go fast!
