FlufferNutter Cookies

My parents make me a grand total of 2 FlufferNutter sandwiches when I was a kid. Both of these 2 sandwiches were for my birthday, and both of them were absolutely amazing. I did not grow up surrounded by sweets, by any stretch of the imagination, which is probably why I am so crazy about them now. Because neither of my parents were really fans of the sweet stuff, both of these sandwiches were adulterated with slices of banana. I'm sure that this was my parent's attempt to make the sandwich resemble an actual meal instead of a dessert, and instill in me a habit of healthy eating, but it sort of had the opposite effect. Instead, it instilled in me a deep love of the combination of peanut butter, marshmallows, and bananas. They have been combined with graham crackers and chocolate in many s'mores, and even found their way into a cookie. A really really good cookie, by the way.

These cookies are made with browned butter and whole wheat pastry flour to really bring out the toffee flavor, and impart a warm flavor that tastes a little like graham crackers. You could totally add a healthy helping of dark chocolate to the mix, something I seriously wish I'd done. Instead, I used chocolate marshmallows, because they were the only ones I had on hand. I found out the hard way that they taste no different from the regular white kind, so I don't recommend spending the extra couple bucks for the brown sort.
The marshmallows will also melt out of the cookies and caramelize on the pan, so make sure you use parchment or a Silpat, and DO NOT overcook these guys, because the caramel surrounding the cookies is one of the best parts.

Mmmmm... Gooey caramelized marshmallow

FlufferNutter Cookies
Makes about 30 cookies

2 cups whole wheat pastry flour
1 1/2 tsp baking powder
1/4 tsp salt
1 stick of butter
1/2 cup creamy peanut butter
1 cup gently packed light brown sugar
1 egg, 1 egg yolk
2 tsp vanilla
2 very ripe bananas, mashed
1 1/2 cups mini marshmallows
1/2 tsp flaked sea salt

Preheat oven to 350ºF, line 2 large (3 normal sized) baking sheets with parchment paper.
Brown the butter by heating, with salt, over medium-low heat until golden flecks start to sink on the bottom. Remove from heat, cool slightly, and add the peanut butter, mix until smooth, and cool completely.
In a medium bowl, cream together the eggs and sugar. Mix in the vanilla and mashed bananas. The mixture will be not quite smooth.
Whisk in cooled butter mixture. Add flour, baking powder, and salt. When the wet and dry ingredients are well combined, gently fold in the marshmallows.
Try adding them in 4 batches. Marshmallows seem to have a weird magnet effect and don't want to spread out from each other if you add them all at once.
Scoop the dough into 1" balls, tucking in any marshmallow pieces that seem to be coming out of the ball, to make sure they don't spread around the pan too much, press down to flatten slightly. Bake on the middle racks for 9-11 minutes, until golden, but still soft. They will start to smell like the marshmallows that kids used to burn at camp after they're cooked about half way. Don't freak out, they're not burning, they're just oozing caramel. But this also means that you'll have to be super careful about the timing. Remember, when in doubt, take them out. Underdone is always, always, always better than overdone.

Just thought I'd throw in another picture, as if you weren't tempted enough already
