Turn the oven on to 350°F (175°C). Grease a standard 12-cup muffin tin or line it with paper liners.
02 -
Use a medium-sized bowl to whisk the flour, baking soda, and salt until they're evenly mixed. Keep it to the side for now.
03 -
In a larger bowl, beat the softened butter, brown sugar, and granulated sugar with a mixer on medium until the texture is creamy and smooth. This should take 2 or 3 minutes.
04 -
Mix the peanut butter into the sugar mixture until it’s completely blended. Next, toss in the egg and vanilla, beating until everything's light and airy.
05 -
Gradually add the bowl of dry ingredients to the wet mixture. Stir slowly until just blended. Be careful not to mix too much, or the cookies won’t turn out soft.
06 -
Fold ¾ cup of the chocolate chips into the dough using a spatula or wooden spoon, setting aside the remaining ¼ cup for topping.
07 -
Scoop the dough evenly into the muffin tin cups, filling each about ¾ of the way. Sprinkle the leftover ¼ cup of chocolate chips on top of each one.
08 -
Pop the muffin tin into the oven and bake for 12-15 minutes, or until the edges are golden and the centers remain slightly soft.
09 -
Once out of the oven, let the cookie cups sit in the tin for about 10 minutes so they can firm up. After that, carefully transfer them to a wire rack to cool completely.

Enjoy the cookie cups warm for a melty center or at room temperature for a chewier bite. You can top them off with ice cream, chocolate drizzle, or caramel sauce if you're feeling fancy!
