Preheat oven to 350°F. Line one or two baking sheets with parchment paper and set aside.
In a large bowl, combine 1/4 cup smooth peanut butter, 1/4 cup coconut oil or softened butter (choose one), 6 tablespoons brown sugar, and 1/4 cup granulated sugar. Beat or cream together until smooth and slightly fluffy.
Add 1 egg and either 1/2 teaspoon vanilla extract or 1/4 teaspoon vanilla bean paste. Beat until the mixture is lighter in color and fluffy, about 2 minutes.
Add 1/4 teaspoon baking soda, 1/2 teaspoon salt, 1/2 cup all-purpose flour plus 1 tablespoon flour, and 1 cup quick cooking oats. Stir slowly until just combined.
Fold in 3/4 cup baking chips (butterscotch, chocolate, white, etc.) and 1/3 cup Rice Krispies cereal by hand until evenly distributed.
Using a cookie scoop, portion 18 even mounds of dough onto the prepared baking sheet(s). Leave at least 2 inches between mounds for spreading. Gently press each mound into a flat disk large enough to hold one snack-size Snickers.
Place one unwrapped snack-size Snickers candy bar on top of each flattened dough disk. Using the cookie scoop, place another scoop of dough over each Snickers. Press and pinch the top and bottom dough together around the candy until the Snickers is completely enclosed and the cookie is a smooth round.
Bake in the preheated oven 9–11 minutes, or until the bottoms of the cookies start to turn light golden brown.
Let the cookies cool on the baking sheet 3–5 minutes, then transfer to a wire rack to cool further. Serve warm if desired.
