• Preheat the oven to 350°F.

Make the Cookie Dough

• Add the softened butter to a large mixing bowl along with the sugars.
• Use an electric hand mixer to cream the ingredients together on medium-high speed for about 2 minutes, or until smooth.
• Add the egg and vanilla and mix again until the egg is fully incorporated with the creamed sugar.
• Once combined, whisk in half a cup of peanut butter.
• Reduce the speed of your mixer and gently whisk in the flour, baking powder, and baking soda. Make sure no dry pockets remain anywhere in your cookie dough.

Shape and Bake

• Use a standard size cookie scoop (I used a #40 scoop) to drop balls of dough onto a large baking sheet, leaving about 2 inches in between each cookie.
• Bake your cookies for 11 minutes.
• As soon as your cookies come out of the oven, top each one with a few pieces of chopped Snickers.

Add the Peanut Drizzle

• Heat your remaining peanut butter in the microwave for about 30 seconds, stirring halfway through.
• Drizzle the warm peanut butter over your cookies.
