Instructions

1. To make frosting, in bowl of stand mixer fitted with paddle attachment, beat 2 tbsp (30 ml) butter and cream cheese until smooth. Add icing sugar and Irish cream and mix until well combined. Transfer to an airtight container, cover and refrigerate until ready to use. Frosting may be made up to 1 week in advance.
2. Preheat oven to 350 F (180 C). Line 2 baking sheets with parchment paper and set aside.
3. In clean bowl of stand mixer fitted with paddle attachment, cream together remaining ¾ cup (175 ml) butter, brown sugar and ½ cup (125 ml) granulated sugar until light and fluffy, about 4 minutes. Add egg and vanilla and mix until well combined.
4. In a medium bowl, whisk together flour, cornstarch, baking soda and salt. Add to ingredients in bowl of mixer and mix on low until well combined.
5. Place tablespoon-sized balls of dough on lined baking sheets. Refrigerate for 15 minutes, then bake until edges just start to brown, 8 to 10 minutes. Allow cookies to sit for 2 minutes on sheet before transferring to a wire rack to cool completely. Cookies may be stored in an airtight container in refrigerator for up to 1 week, or frozen for up to 1 month.
6. When ready to serve, place remaining ½ cup (125 ml) granulated sugar in a small bowl. Spread 1 heaping tbsp (about 15 ml) frosting onto each cookie, then press into granulated sugar, coating frosting. Place on an unlined baking sheet, sprinkle a little extra sugar over top of each cookie and, using a kitchen torch placed very close to cookies, caramelize sugar. Set aside to cool a few minutes before serving.
