Giant Peanut Butter Cup Marshmallow Cookies

With Easter right around the corner I thought it’s be fun to use some Easter candy I found at Target last week. Reeses Peanut Butter Cup Minis! Have you seen them? They are absolutely adorable and come in a bag individually unwrapped. Perfect for some fun festive cookies 🙂

I also used my Muffin Top Pan that has been a favorite of mine since last year. If you haven’t picked up a muffin top pan yet you absolutely must. It makes the best giant cookies ever!

Here’s your line up of ingredients….and those cute PB cup minis 🙂

How to Make The Best Peanut Butter Cookies

Let’s cream the butter and sugars to start.

Add a lovely egg.

Some vanilla.

Time for the dry ingredients!

Love, Love, Love these Marshmallow bits in cookies. You can find them at Target.

Add some chocolate chips please 🙂

Time to give her a good mix.

Scoop 2 scoops of dough into your muffin top pan and press to flatten.

Ahhhh, here they are! Love these.

Aren’t they cute?!


Press about 5 cups into each cookie and time to bake.

You get perfectly round giant lovely cookies. Enjoy!

Can’t wait for you to try these!

    If there’s a Trader Joe’s near you, they have mini dark chocolate PB cups that are better than Reese’s.

    Made these last night. They were a huge hit. My son thought the mini marshmallows were almonds, so he didn’t want to try them. It took some convincing (tasting the marshmallow bits separately)and he loved them. I hope you come up with more recipes using those marshmallow bits. Thanks for a great recipe.

    You always come up with the best ideas! Every time I read your blog I think: “How have I never thought of that? And how have I lived my life without eating that?!?!”.

    I plan on buying a muffin top pan this weekend and baking an unhealthy number of giant cookies. Thanks for the inspiration! 🙂
