Preheat your oven to 375°F (190°C). This temperature is crucial for getting that perfect bake. While the oven heats up, line two large baking sheets with parchment paper to prevent the cookies from sticking.
In a large mixing bowl or the bowl of a stand mixer, combine creamy peanut butter, vegetable shortening, packed dark brown sugar, milk, and pure vanilla. Mix on medium speed until everything is well blended. You’re looking for a creamy and smooth consistency.
Add in the large egg and continue mixing until it’s fully incorporated into the batter. This will add moisture and richness.
In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. This step ensures even distribution of the leavening agent and flavor.
Gradually add the dry ingredients to the wet mixture, about one third at a time, mixing on low speed. This prevents flour from flying everywhere and ensures a smooth dough.
Once fully combined, you’ll have a thick and slightly sticky dough. It should hold together well but not be too dry.
Using a tablespoon, drop portions of the dough onto the prepared baking sheet, spacing them about 2 inches apart. Remember, these cookies will spread while baking, so don’t crowd them.
Take a fork and flatten each cookie slightly, making a crisscross pattern. Press down gently to avoid flattening them completely. This little touch makes them look classic and inviting.
Bake the cookies in the preheated oven for 7 to 8 minutes. Watch them closely; they should be set but just starting to brown at the edges. Overbaking can lead to hard cookies.
Remove the baking sheets from the oven and let the cookies cool for about 2 minutes before transferring them to a cooling rack. This cooling period is essential for allowing them to firm up.
Once completely cool, enjoy your Irresistible Peanut Butter Cookies! They’re perfect with a glass of milk or as a sweet treat anytime.
