I’ve been meaning to use Reese’s colorful Easter Eggs in baking since I saw them on the shelves just before Valentine’s day. Of course I ate a few bags before I actually used some, but hey, that’s the taste testing part.
These peanut butter cookie bars with Reese’s peanut butter eggs may have a long and sort of complicated name but there’s nothing complicated about making them.
And the taste, mmm, just like a melt-in-your-mouth peanut butter cookie. Soft, crumbly with a strong peanut butter taste and the addition of both peanut butter chocolate eggs and candy peanut butter eggs improves their texture and color.

And since I got a little excited about these Reese’s eggs I used two whole bags. The peanut butter chocolate ones I buried them inside the cookie dough for an extra peanut butter surprise and topped with the colorful ones. All I can say it’s Peanut Butter Lover’s Heaven in one bite.
If you don’t have Reese’s peanut butter eggs on hand you can use the chocolate peanut butter cups or, for a chocolate touch you can use Hershey’s milk chocolate eggs or the Reese’s pieces, like M&M’s. Whatever you choose these peanut butter bars are worth making them. And not only they are irresistible, they are so easy to make.

You start by creaming the butter and peanut butter with the brown sugar until creamy and fluffy, add the eggs and flour and spread the dough in the prepared pan. Add the Reese’s eggs and bake. It’s that simple.
The hardest part? Unwrapping a whole bag of Reese’s Peanut Butter Eggs!!!

Roxana, these are just darling! I love the egg background.
Those pretty much need to be boxed up and shipped to me immediately. Or, I guess I could just make some.

You know I love my peanut butter, I am pretty sure a whole pan would be done in a day with me around!

These look great! Do you think that the peanut butter M&M’s would work instead of the Reese’s Chocolate Peanut Butter Eggs? I haven’t seen the Reese’s Eggs this year, I thought I would try to swap them out!
Hi Kristin,
You can use the regular chocolate peanut butter cups inside the cookie dough and sprinkle the Reese’s M&M’s on top.
Happy baking,
Roxana
These bars are so pretty with the pastel eggs and I know they are tasty too. Peanut butter eggs are one of my favs. and put them in peanut butter bars, oh yeah!
And we are all so glad that you did finally use those eggs! YUM!
Okay, what. I didn’t know about the existence of either of those Reese’s products! I absolutely need to get my hands on some of them! Yummy.
And these bars are just what I need right about now. Or any time. Love the loads of peanut butter.
OMG! I love those little peanut butter eggs…
The Reese’s Pieces eggs are the best! I don’t know why but they taste better than regular Reese’s Pieces. Adding them to bars is a great idea!
We’re having an Easter party at home, so these will be perfect for the kids…and adults alike! We love Reese’s peanut butter-anything at home. My husband will be in heaven when he sees / tastes these! another awesome recipe, Roxana!
I always have to buy extra bags of Reese’s when I want to bake because I can’t stop eating them! These bars are insane…I love love LOVE all the peanut butter action going on in them!!!
I need to go stock up on Reese’s peanut butter eggs and candy pastel eggs and all kinds of peanut butter treats so that i can make this asap! Love these, Roxana. And they’re too adorable for words.
You always come up with the perfect holiday-themed treats!
Glad I’m not the only one who “taste tests” their candy before baking with it.
Could you please send over a batch?
