Peanut Butter Krispie Cookies

A recipe for a crispy peanut butter cookie with crisped rice cereal.

Source: I found this recipe at Picky Palate, but changed it slightly to suit my purposes.  And my pantry.

Yield:  About 2-3 dozen

I chose and discarded about 10 recipes last night.  I guess some days you just can’t find what you are looking for.  The thing I was looking for was a cookie that did not involve a trip to the grocery store.  I was ultimately unsuccessful in that.  I also wanted a cookie that would add to a fun Friday night, and I failed there as well.  On the bright side, the cookie I eventually came up with was really fun and delicious!

My husband suggested I make something with Rice Krispies in it, which I thought was a great idea.  I mean, candy bars can do it, why not cookies?  I found precious few recipes to work with, however.  Jenny at Picky Palate made these fun [tooltip text=”I normally don’t advertise this, but Cap’n Crunch is my favorite breakfast cereal. Especially the peanut butter variety. I’m kind of like a 5 year old that way.”]Cap’n Crunch[/tooltip] cookies, but I wanted to try them with Rice Krispies instead.

My Friday night turned out quite sadly, actually.  A cousin was in the hospital with her 11 month old daughter, and we visited for a while.  I didn’t feel much in the mood for cookies after that.  Saturday morning, I used the last two eggs in the house to make breakfast for my husband, and was then forced to go to the grocery store.  On a Saturday.  Sad face.

My other life (piano teaching) collided with my baking life after I got back from the grocery store, and my daughter did the bulk of the baking while I helped my niece prepare a piano/vocal version of “Someone Like You” by Adele for her upcoming pageant.  I took a break to sample the dough.  I was glad I did.

Remember the Peanut Butter Sandwich Cookies?  They have such a strong, rich, creamy peanut butter flavor, it’s almost overwhelming.  Almost. Not so much with this peanut butter cookie.  It’s understated, crunchy, and great with [tooltip text=”And Diet Dr. Pepper”]milk[/tooltip].  And the dough is even better.

The offspring wisely smashed the cookies a bit before baking, since the dough was a bit on the heavy side.  They baked for 10 minutes, but may have been okay with just 9.  I do think I will increase the butter a little next time I make them, to keep them from getting too dry.

At some point, I may try these with the Cap’n Crunch.  I may even try them with Peanut Butter Cap’n Crunch.  Today I just want another cookie, and another glass of Diet Dr. Pepper.

    Try this for no-grocery-store-trip-necessary peanut butter cookies:
    1 c. peanut butter
    1 c. sugar
    1 egg
    1 tsp vanilla

    Bake at 375 for 8 min (i think)

    They sound pretty good, but I can’t guarantee that won’t require a trip to the grocery store!! 😀
