I don’t even know where to begin with these banana cream pie cookies. They’ve got real banana, pudding mix, white chocolate chips, vanilla wafers, and marshmallows! Yum! And, even though these cookies have real banana in them, they still have a cookie consistency — the banana makes them soft, but the cookie texture remains!
These cookies are a copycat of Last Crumb’s banana cream pie cookie. Last Crumb is a popular LA-based cookie company that has highly sought after cookies that they ship out. Their cookies are really pricey and hard to get, so this recipe is for anyone that’s always wanted to try their cookies, but haven’t gotten the chance! Or if you’ve had them and love the banana cream pie flavor. Or if you’ve never tried them and just think a banana cream pie cookie sounds great. You are all welcome here and you will all love these cookies!
ingredients for these banana cream pie cookies
- butter
- brown sugar
- box of instant vanilla pudding
- banana
- eggs
- vanilla
- flour
- cornstarch
- baking soda
- salt
- vanilla wafers
- white chocolate chips
- mini marshmallows
tips and tricks
These cookies have real banana in them, which is what makes these so good. But, its helpful to use ripe bananas! They bring a natural sweetness that works perfectly in these cookies. So find your ripest, most spotted banana. If you don’t have a super ripe banana, don’t worry — just use the ripest banana you have and it will work fine.
Each time I tested this recipe I used a box of instant vanilla pudding. I never tried non-instant pudding. I don’t see why these wouldn’t work with non-instant pudding, as we are just using the pudding mix to help soften the cookie, but I never tested it! So if you want the true and tried way, stick with instant pudding.

banana cream pie cookies
Ingredients
- 1 cup butter cold
- 1 1/2 cups brown sugar dark or light
- 3.4 oz box vanilla instant pudding mix
- 1/2 cup mashed banana
- 2 eggs
- 1 tsp vanilla
- 3 1/2 cups flour
- 2 tbsp cornstarch
- 1 tsp baking soda
- 1 tsp salt
- 1/2 cup vanilla wafers crushed into pieces
- 1/2 cup white chocolate chips
- 1/2 cup mini marshmallows
Instructions
- Preheat the oven to 350. In a large bowl or stand mixer, combine butter and brown sugar. Mix for 2 minutes until the butter and brown sugar is completely combined.
- Add vanilla instant pudding mix, mashed banana, eggs, and vanilla. Mix until combined.
- Add flour, cornstarch, baking soda, and salt. Mix until just combined. Add vanilla wafer pieces, white chocolate chips, and mini marshmallows. Mix until just combined.
- Scoop the dough out and transfer to a lightly greased or lined cookie sheet. For large, Last Crumb style cookies, use 1/2 cup of dough per cookie. For smaller cookies, use 1/4 cup of dough per cookie.
- Bake for 10-12 minutes, until cookies are barely starting to brown. Let the cookies cool and enjoy!
- Store any extra cookies in a sealable container for 3-4 days. The cookies will get even softer each day.
These cookies have ruined all other cookies for me. They are SO good! They’re pillowy soft on top but like she said, they set up like a regular cookie. I froze my dough before baking and I was worried that maybe they weren’t cooked all the way through. Bit my fears were quickly dashed the moment I took a bite of these. Omg amazing!
AH this makes me so happy!! i’m so glad you loved them. and i’m glad they worked after freezing them! that’s a great way to save extra dough.
When you say vanilla wafers do you mean the vanilla cream wafer cookies or nilla wafers?
nilla wafers!

Is it ok if I have I only have half the amount of pudding mix? Will it affect the recipe?
hi! this will alter the recipe, but i don’t think it would modify it significantly enough that it would be a big deal.
Highly recommend?

Hi! These sound delicious and I’d like to try them. I just went grocery shopping yesterday and didnt buy bananas.
Do you think that I could save a trip back to the store and just used some frozen mashed bananas that Ive been hoarding for banana bread? I would just drain off the excess liquid…
Thanks!
hi! sorry i am getting back to you a few days later. frozen bananas will work if you defrost them and get off all the extra liquid!

Can the dough be made ahead of time and frozen? Or is that not ideal since it uses fresh bananas?
it can totally be frozen! just be sure to form it into dough balls first. you might need to add a couple minutes to the bake time if baking from frozen.

Hi! Do you mind sharing what cookie scoop you use for 1/2 cup of dough?
hi! i use my 1/4 cup scoop and scoop two balls of dough, then combine them! i haven’t been able to find a good cookie scoop that large yet, but i’ll let you know if i do!

I have instant banana pudding mix, not vanilla, do you think this would make a huge difference, or any suggestions on altering something to make it work?
yes that will work totally fine! it will just have a stronger banana flavor.

Wanted to love these…but they are just too soft. Almost like a bread. I had to bake over 20 mins as well. They’re just not doing it for me. They seem like banana bread but in cookie shape.
hi! i’m so sorry these didn’t turn out for you. they definitely aren’t supposed to be a bread consistency! if you want to attempt them again, feel free to email me (thepalatablelife@gmail.com) and i can help you figure out what went wrong!

Could you use banana pudding mix instead of vanilla?
yes, totally!

I loved these cookies, but I did not like the way the marshmallows melted onto the pan. The second time I made them, I did not mix the marshmallows into the dough. As I was putting the dough into balls, I used the dough to make a little tomb for the marshmallows to go in the middle of the cookie. This allowed for the same yumminess, with less mess!!
yay! i’m glad you found a method that worked better for you, because those marshmallows can definitely get messy!
I baked these and loved them. But others in the house are not banana fans. So I swapped strawberry puree for the banana. They had to bake a bit longer, but they are now our official Valentine’s cookie.
oh!!! what a fun idea! i’m glad you liked the strawberry version!

So I made these cookies a while back, and they were amazing! This time I accidentally used banana cream pudding mix and they tasted super artificial (don’t make this mistake!!)
yes the artificial banana flavor is just not it!!!!!

One of the better banana cookie recipes I have found!
I did this 2x and the first batch were really soggy and wet and falling apart, so I baked them again for longer and the second batch turned out better.
I appreciate that you included an exact amount of banana because banana cookies are very tricky. I am disappointed that my first try didn’t work, but they are still really tasty and I might make them again, but maybe smaller.
Your recipes are always so tasty!

These are seriously the best cookies I’ve ever tasted! And I shared them with both my husband’s and my co-workers and they all said they were the best cookies they’ve ever tasted too! My husband’s co-manager said she dreamt about them that night 🙂 Thank you for this recipe!
AH so happy to hear this! and dying that they made it into her dreams hahaha. glad everyone enjoyed!!
These are fantastic, I use banana pudding mix instead and have made them for countless sales. These are always a fan favorite.
YAY so glad you enjoyed this one!! and using banana flavor pudding is a great idea.
Hi can I use cake flour instead?
sure! it will change the texture slightly, as cake flour has a lower percentage of gluten, but the cookies should turn out fine.
These are amazing! Rave reviews from everyone who tried them. And I like that they’re simple enough to make with little kids (plus the kids enjoyed snacking on the various mix-ins, haha).
yay so glad everyone loved these! and i’m with the kids, always snacking on the mix-ins!
