Preheat oven to 350°F (175°C) and line two baking sheets with parchment.
Cream butter, sugar, and peanut butter until light. Beat in egg and vanilla until combined.
Whisk flour, baking soda, and salt; add to wet ingredients and mix until just combined.
Stir honey and sriracha into dough; taste a tiny bit to check heat and adjust if needed.
Roll dough into 1-inch balls and place 2 inches apart on sheets. Bake 8–10 minutes until edges set.
Immediately press a chocolate kiss into each cookie; let cool on sheet 5 minutes, then transfer to a rack.
