When you’ve got ripe bananas don’t make banana bread, make banana peanut butter cookies! These soft and chewy cookies are also packed with dark chocolate morsels and a hint of cinnamon to make a bakery quality cookie right from your kitchen.

INGREDIENTS

Here’s what you need from your fridge and pantry to get these banana cookies made this week!

  • All purpose flour.
  • 1 ripe banana, you really need it RIPE or else you won’t get that banana flavor in the cookies.
  • 1 stick of butter, browned
  • Egg.
  • Baking soda.
  • Salt.
  • Cinnamon.
  • Vanilla extract.
  • Brown and white sugars.
  • Dark chocolate morsels.

For me usually it’s just the ripe banana I’m missing, so make sure you pick up some bananas this week since it can take about 5-7 days for a green banana to fully ripen.

THE BEST BANANAS FOR BAKING COOKIES

There can be some disagreements on which bananas are best for eating, but when it comes to baking there’s really no competition. When it comes to baking, you really need fully ripe bananas. If you use bananas that are still green or just yellow without some browning of the skin the flavor just isn’t quite “bananay” enough.

When you buy bananas from the store and they are still green its going to take about 5-7 days for them to get fully ripe and that perfect for baking flavor. So plan ahead for these cookies!

Can you use frozen bananas? For cookies, I recommend either using room temperate bananas from the counter or from the fridge. I don’t recommend using bananas that have been frozen. I find that freezing bananas, while great for breads and cakes, can add too much unneeded moisture into a cookie and can change the consistency.

For these I used a banana that I had popped in the fridge for a few days and they came out perfect!

The great thing about these cookies is:

  • No chill time needed! This cookie dough doesn’t need to chill in the fridge. Just mix and bake.
  • No special storage. Just keep these covered on the counter. For best cookie texture, enjoy within 3-4 days.
  • No special equipment needed. You’ll only need your standard kitchen supplies, nothing special or unique!
  • Uses ripe bananas. I mean how many bananas breads can we make? Next time you’ve got a ripe banana and not sure what to do with it you can make these cookies.

  • Author: aseasonedgreeting
  • Prep Time: 15 minutes
  • Cook Time: 10 minutes
  • Total Time: 25 minutes
  • Yield: 24 cookies
  • Category: Cookies
  • Method: Bake
  • Cuisine: American

Ingredients

1 large ripe banana, mashed
2 cups all purpose flour
1 stick butter, browned (instructions below)
1/2 cup creamy peanut butter
3/4 cup dark brown sugar, lightly packed
1/2 cup white sugar
1 egg
1 teaspoon vanilla extract
1 teaspoon baking soda
1/2 teaspoon salt
1/4 teaspoon cinnamon
3/4 cup dark chocolate morsels

Instructions

1. Preheat the oven to 350 degrees.

2. Start by making the brown butter. Place a light colored pot over medium heat, then add the butter. After the butter is melted adjust the heat higher to medium-high. Allow the butter to come to a rapid bubbly simmer. While adjusting the heat between medium and medium-high, continually whisk the butter until the milk particles have browned and the liquid is a rich caramel or amber color. I’ve found that once the butter is melted this process takes 4-5 minutes. Once fully browned, immediately pour into a heat proof bowl.

3. While the butter cools slightly, combine the dry ingredients in a large bowl: flour, salt, cinnamon, baking soda.

4. To the brown butter whisk in first the brown sugar, then white sugar, then the egg and vanilla. Next, stir in the mashed banana and lastly the peanut butter.

5. Slowly add the dry ingredients to the wet and stir to combine, mixing in the dark chocolate morsels.

6. Form medium sized cookie dough balls and roll in your hand and add to the baking sheet. Gently press down on the cookies just slightly if you want your cookies a little flatter (optional!).

7. Bake cookies for 10 minutes, then immediately remove to a plate to cool.

Enjoy!
