It was probably a pound cake, but you can make a decent cake that will hold up to poking and glazing by using a regular cake mix (lemon is good), then adding four eggs, a box of instant pudding, the called for oil and a cup of water. I like to skip the oil and use a cup of sour cream for the liquid, but that might be a little moist for your purposes. Your cake sounds good. I'd use a white cake mix - the BC Vanilla is good, and use the whole eggs, not just the whites.
