Peanut Butter Sandwich Cookies with Soft and Creamy Filling

The Best Peanut Butter Sandwich Cookies 

Everyone has had peanut butter cookies… but these… these are the kind people remember. My husband has said they were the best cookies he’s ever had, peanut butter or not, and I understand it… they are so good!

After testing a few versions, I landed on a soft peanut butter cookie with just a bit of oatmeal for texture and a creamy peanut butter filling sandwiched in between. They’re rich, nostalgic (I feel like peanut butter cookies were the thing when I was younger), and just slightly over the top in the best way.

🥜 Why You’ll Love These

• Soft and chewy with just a hint of texture
• Creamy peanut butter filling
• Easy pantry ingredients
• Perfect for holidays or everyday baking

🥜 What You’ll Need

These are simple pantry staples — nothing fancy.

For the Cookies

• Peanut butter
• Butter
• White sugar
• Brown sugar
• Egg
• Vanilla
• Flour
• Baking soda
• Baking powder
• Salt
• Quick oats (for texture, not taste)

For the Filling

• Butter
• Peanut butter
• Confectioners’ sugar
• Heavy cream

That’s it. If you bake even occasionally, you probably have most of this already.

🥜 Kitchen Tools I Love for These Cookies:

• Stand mixer or hand mixer
• Cookie scoop (makes even sandwich sizes)
• Cooling rack
• Parchment paper

Sugar note… these aren’t a health food and that is ok sometimes! My husband wanted these instead of cake one year for his birthday and they make a special treat for a movie night or family game night. There is something to be said for homemade treats shared around the table. That’s the balance of real life.

Having said that, you could use a product like Swerve (which is Keto friendly), and you would need the trio pack for these… if you wanted a less sugar loaded option. Sugar substitutes do have their own issues… but sometimes they are needed. If you do make these using something like Swerve… I’d love to hear how they turn out!

Peanut Allergy note… I would go out on a limb and say that any nut butter would work. What I might do is give a modified recipe a try with nondairy creamer, sugar substitute, and a nut butter, like almond butter… and see what the outcome is. When I do… I will link it here.

🥜 Making the Cookies

These come together the way most classic cookies do… cream the butter and peanut butter first, then add the sugars, egg, and vanilla. Once the dry ingredients are mixed in, the oats give just a bit of texture. Bake until just set, then sandwich with a creamy peanut butter filling once cooled.

🥜 A Sweet Way to Celebrate March

These peanut butter sandwich cookies are especially fun to make for National Peanut Lovers Day (March 15), but March actually gives us two reasons to bake. Peanut Butter Lovers Day falls on March 1, so you truly have double the excuse for a cozy kitchen afternoon.

I’ve included this recipe in March’s chapter of my Family Binder as a simple mid-month baking idea… something easy, familiar, and just a little special. Whether you’re marking the calendar or just craving something sweet, these are always a good choice.

If you try these peanut butter sandwich cookies, I’d love to hear how they turned out. Leave a comment below or share a photo and tag me on Instagram or Facebook @bemandfam so I can see your kitchen creations (successes and experiments both count 😉).

Stay sweet,

BEM and Fam 🙂
