How to make Peanut Butter Brownie Cookies
To make these cookies, simply grab a small bowl and whisk together the flour, cocoa powder, baking powder, and salt. Set aside.
In a microwave-safe bowl, add the chocolate and butter. Heat in 30 second intervals, stirring after each one, until melted and smooth. Set aside.
Using either a hand mixer or a stand mixer fitted with the whisk attachment, beat together the eggs and sugar until pale, fluffy, and tripled in volume – about 5 minutes.
Add the chocolate mixture and vanilla extract, and whisk until combined.
Add the dry ingredients and fold in until smooth and combined. The batter will be very runny.
Refrigerate for 15 minutes until thickened slightly, and resembles more like a thick brownie batter when mixed.
Using a small cookie scoop, divide all of the batter out between two large baking trays lined with parchment paper or silicone mats.
NOTE: Scooping out all of the dough at once onto baking trays is key to shiny, crinkly tops on all cookies.
Bake for 10 – 12 minutes (one tray at a time) or until the tops are shiny and cracked, and the cookies have domed slightly.
Allow to cool on the baking trays for at least 15 – 20 minutes (they will be very soft) before transferring them to a wire rack to cool completely.
In a small bowl, mix together the peanut butter and melted butter until creamy and completely combined.
Add the icing sugar, cream, and vanilla, and mix until light and fluffy.
Frost the back of one cookie and sandwich with another. Repeat with all of the cookies.

NOTE: For best results, I highly recommend using the gram measurements (with a digital scale), rather than the cup measurements.
Cup measurements are simply not accurate enough, and I cannot guarantee the best results if you use them.

How long will these cookies last? These cookies will stay fresh, stored in an airtight container, at room temperature or in the fridge for up to 1 week.
