How to Make Peanut Butter S mores Cookies
Prepare the dough the night before baking, or at least 4 hours prior. This chilling step is essential for achieving a perfect texture and flavor.
Process the graham crackers in a food processor until you have fine crumbs (60g or ½ cup). They should resemble sand in texture for even distribution.
Melt the butter (113g or ½ cup) in a large heatproof bowl, using either the microwave or a saucepan, ensuring it s fully liquid but not hot.
Mix together the sea salt, vanilla extract, brown sugar (67g or cup), and granulated sugar (100g or ½ cup). Whisk until combined, then heat in the microwave for an additional 30 seconds.
Whip the mixture for about 30 seconds until it becomes shiny and cohesive. Carefully add the egg and whisk again until it s glossy.
Combine the creamy or chunky peanut butter (135g or ½ cup) into the mixture, whisking until well blended. Next, add the baking powder ( ½ tsp), baking soda ( ½ tsp), flour (170g or 1 ¼ cups), and graham cracker crumbs. Stir gently with a rubber spatula until there are no streaks of flour.
Cover the bowl with plastic wrap and place it in the fridge overnight or for at least 4 hours. This step ensures the flavors meld beautifully!
Preheat your oven to 350 °F (175 °C). While it heats, grease and line two cookie sheets with parchment paper to prevent sticking.
Scoop out dough balls using a cookie disher, about 1 ½ tablespoons per cookie. Remember to leave enough space in between for them to spread as they bake!
Indent the center of each dough ball using the bottom of a tablespoon or your thumb, creating a well for the filling. Add about a heaped teaspoon of marshmallow fluff into each indention, then gently place a peanut butter cup on top, centering it perfectly.
Bake the cookies in your preheated oven until they ve spread and the chocolate is fully melted, about 10 minutes. Watch for the edges to turn golden brown! Optionally, sprinkle extra graham cracker crumbs on top, then let them cool on the pan.
Optional: Serve warm for an extra gooey experience!
