You’re almost there.
Get a bucket for the wine bottles. You don’t have to leave the shopping bags there. She will know that YOU made her favorite dessert, because it won’t taste better than the one at the bakery. But there’s nothing to worry about. She’ll love it anyway.
Oh, and make sure the kitchen counter is empty. You never now where Valentine’s Day will take you…

P.S. For those who don’t have a girlfriend, cut the bullshit. Leave the bags there, cook some pasta, and put as many bottles of wine in the cooler as you can before telling your buddies to come over.
