These delicious biscuits taste like eggnog. You can substitute 1/4 teaspoon rum essence and 1 tablespoon milk for the rum, if you prefer.
I have been making these cookies since 2000, and every year, they are my biggest request. My family literally beg me to make them. The cookies are simple, but combined with the flavorful frosting filling, are absolutely spectactular! I've made them multiple ways, using either butter or margarine, rum or rum extract in the filling, ditto for the cookie base, and they turn out very good with any combination. I fill these with a pastry bag and star tip - very cute if I do say so myself Using real butter (& pastry bag), the filling does get very soft if your hands (or home) are hot, so I just stick the bag in the fridge for a while. I have never had a problem with the frosting "not setting up". Try them - you'll be glad you did! - 03 Dec 2005 (Review from Allrecipes USA and Canada)
Very good cookie!! It's true - it's not very colorful, but the taste was wonderful! If you're having trouble spooning the filling into the cookie, use a decorating tube, or a plastic sandwich bag with a courner snipped out. I had no trouble with the spoon - and no trouble getting my co-workers to eat them, too! Lots of compliments! I'm a bit confused that a previous reveiwer had runny filling...with the given ingredients in the correct amounts, it shouldn't have happened. I'm curious as to what they did to make it "runny"! One thing I was particularly impressed with...whenever a cookie recipe calls for filling such as this, there ends up being either way to much filling, or not enough. This turned out to have EXACTLY the amount needed - no more, no less! How cool is that? These would also be excellent to package up and send through the mail. - 23 Dec 2001 (Review from Allrecipes USA and Canada)
I have been searching for the perfect egg nog cookie recipe for 6 years... and I this is by far my favorite. I have made 2 batches. The dough comes out beautifully. I think next time I make it I will use rum flavoring instead of the vanilla flavoring in the cookie. I did mix the flour in with my KitchenAid on Stir, and baked on parchment paper, and they baked beautifully. I did modify the filling recipe a little. I used 2 tsp. rum flavoring, 2 tsp milk, and 1/4 tsp. of nutmeg, (probably an extra tsp of powdered sugar as well). It makes this frosting taste just like egg nog. So delish! This recipe has won a place in my annual holiday "must have" cookies. - 21 Dec 2008 (Review from Allrecipes USA and Canada)
