I went on a quest to come up with the same recipe for Costco's Aussie bites. I tried several online recipes and tweaked and tweaked to get it just right. While I never did achieve the same taste and texture as Costco's, I did come up with a recipe that I like just as well as theirs. Please note that this recipe is designed to work perfectly with the Calphalon mini-muffin tin which is slightly larger than your standard mini-muffin pan. (A medium cookie scoop (1.5 Tbsp) also works perfectly to divide the batter evenly between the 24 openings). If using a standard size mini-muffin pan, you will probably get more than 24 muffins and will need to bake them on the lower end of the given range for baking time. You can find the Lyle's Golden Syrup at Whole Foods or online at Amazon. I suppose you could substitute more honey or agave, but the golden syrup is an authentic ingredient in these Australian delights (Anzac biscuits) and really adds a nice caramelized flavor. If you haven't tried golden syrup, I highly recommend it!
