My dad always used to say "Business before pleasure," meaning stuff like you gotta finish your homework before you get to play computer games, etc. I internalized that in the way I eat - start with all the yucky greens, move on to the ho-hum starches, and finish off with the yummy meats and sauces. Same thing with cake - eat out the bready stuff first, leaving a capital "F" shape of vertical walls of straight frosting alone - then go for the all-sugary gold!
So for Oreos, twist off the two dull but barely chocolate-y discs. One will have the white center on it - that's the best part. Eat the dry boring other half, or dip it in milk or something to add at least some flavor.
Now here's the trick: Pass a strand of dental floss between black disc #2 and the 'host'** of white sugar yumminess, which will separate it cleanly. Put up with eating the second nearly-flavorless brown disc. Now hit the white disc like a diamond mined from the sand, except you've already eaten the 'sand.' Enjoy the concentrated full-sugar hit, with NO distractions!
** When visiting my cousins in Quebec ( which used to be VERY Catholic until the 1980s ) we used to do this and play 'Mass' with the white disc and a glass of juice. Then Auntie caught us at it and we were raked over the coals and killed twice over.
