How many times have you ogled the layer cake at your favorite coffee shop, ordered a slice of the vertical wonder, and then sunk in disappointment at its day-old taste and fridge-ridden frosting? Cake by the slice is a risky choice, but not at Dallas Affairs, the Lakewood-area bakery known for its stunning special occasion cakes. At the counter, Dallas Affairs keeps two cakes on hand for by-the-slice orders. One is an Italian cream with cream and pecan frosting; the other, a chocolate fudge with chocolate cream filling. For $3 a pop, it's a little slice of heaven--thick, heavy with flavor, and most important, fresh, fresh, fresh.
