½cup/ 113gsalted butter, ideally European-style
2teaspoons/ 9gdry milk powder, optional
½cup/ 106gpacked light brown sugar
¼cup/ 50ggranulated sugar
1large egg yolk, at room temperature
⅓cup/ 85gmashed banana, from 1 small very ripe banana
½teaspoonvanilla paste, or 1 teaspoon vanilla extract
1 ½cups/ 190gall-purpose flour
½teaspoonbaking soda
½teaspoonbaking powder
½teaspoonfine sea salt, increase to 3/4 teaspoon if using unsalted butter
½teaspooninstant espresso powder, optional
¾cup/ 125gchocolate chips or coarsely chopped chocolate, I use a mix of 70% dark and 50% semisweet chocolate chips
Instructions
To brown butter, combine butter and dry milk powder in a small saucepan over medium heat, until butter melts and starts to simmer and sputter (it will foam up quite a bit). Continue to cook, stirring occasionally, until the sputtering ceases and the butter solids on the bottom start to turn golden brown. Remove from heat and immediately pour into a heat-proof mixing bowl, scraping all the browned bits from the pan, and set aside to cool slightly (below 100 degrees F).
Add brown sugar and sugar to the mixing bowl with the lukewarm butter and stir until evenly moistened.
Add egg yolk and mix well with a whisk or spatula until smooth and emulsified. Mix in banana and vanilla.
In a separate bowl, whisk together flour, baking soda, baking powder, salt and espresso powder until evenly incorporated. Add to the wet ingredients and gently mix just nearly incorporated, with just a few streaks of dry flour remaining. Fold in chocolate chips until evenly distributed.
At this point the dough will be very soft. I recommend chilling for 15-20 minutes first to make it easier to handle, but I still like to shape the dough while it's still fairly soft.
Preheat oven to 350 degrees F. Line your baking sheets with parchment paper.
Scoop dough into 60 grams balls (a scant large cookie scoop) and arrange on prepared cookie sheet, leaving about 2 inches of of space between cookies.
Bake for 11 to 13 minutes or until tops are puffed, center is no longer raw-looking, and the edges have slightly darkened to a golden brown.
Immediately upon removing from the oven, swirl a round cookie cutter around the cookies to tuck in the edges and make them perfectly circular. You can also press a few chocolate chips on top while the cookies are still hot to make for truly picture perfect cookies.
Let cool on cookie sheet for 15 minutes, then transfer to a wire rack to cool completely. Cookies will keep in an airtight container for up to 5 days, refrigerated for up to a week, or in a zip-top bag in the freezer for up to 2 months.
