I've been making these for years (we call them speedy little devils). A favorite of many. Two things I do differently though: bake for 18 minutes (they are a bit more gooey) and I use more peanut butter (approx 3/4 - 1 cup depending on my mood:). Really, when is more peanut butter a bad thing?

Simple to make is about all this recipe has going for it. The result was crumbly and dry and the flavor of chocolate and peanut butter are hidden by overwhelming sweetness. I was disappointed and won't be bringing it to the picnic I'd hoped to share it at.

This was good, but I'd recommend using a smaller pan, and increasing the peanut butter-marshmallow mixture.

I must say, these are quite tasty little treats for such a simple, 4 ingredient recipe....I was pleasantly surprised! After reading all the reviews, I decided to make these into cupcakes to avoid the hassle of trying to spread the filling onto the base in a large cake pan. It worked out very well! Put a tablespoon of the cake mixture down, then a spoonful of filling, more cake mix on top & pressed down lightly. I baked these for about 14-15 minutes & they were perfect! The kids gobbled them 11 year old son said they were "AMAZING"!

Great cookies, especially if you're a chocolate & peanut butter fan!! When I was assembling them, I didn't think it was going work, but they came out wonderfully.

Maybe mine came our PERFECT because I DOUBLED it; used 3/4 butter and used 1 C. PB. I have also used BROWNIE MIX - which is my husband's favorite since it's a little more gooier. I have also tried this with Vanilla mix & lemon pie filling (3/4 can). I have also tried this with Vanilla mix and raspberry pie filling (3/4 can) UMMMM YUMMY ! TAKE OUT BEFORE YOU THINK IT'S COOKED ALL THE WAY... that's why it's dry.

Dry, crumbly, though the flavor was good. I think I will play with this recipe until it is the consistency I enjoy. More filling, less cooking time, less crust all possibilities to improve the texture.

Yummy! Next time I'll put more crumbs on the bottom so the top part of the cookie isn't so thick.
