Tomorrow night we're having girls night @ the bar. The bar will be closed but the female bartender/owner and a few of the female regulars, me included, will be having a sleepover there to decorate for Halloween. She will be providing the drinks obviously (tequila gimlets, ftw!) and even though we are helping her, I still feel like I need to bring a treat since we're drinking for free. What should I make? I was thinking Guinness cupcakes or Baily's brownies. Any other ideas?
PS if I make the Baily's brownies do I just substitute the liquid with Baily's?
