I’m sure there are a ton of these… songs that reference food as a metaphor?
Example: Cherry Pie (referring to a woman, not an actual pie)
Bessie Smith’s I Need a Little Sugar in My Bowl
Sukiyaki
Green Onions has lyrics, who knew?
Led Zep’s The Lemon Song.
Def Leppard’s “Pour Some Sugar on Me”
R.E.M.'s “Orange Crush” (not about the soda)
Garbage’s “Milk”
Rolling Stones “Brown Sugar”
MacArthur Park, American Pie, Milkshake.
again, rap has a ton.
lolipop, candyshop
Sarah Harmer- Coffee Stain
The Shit- Sandwich Song
Hank Williams “Hey Good Lookin’”
Van Halen - Up for Breakfast
Sheena Easton - Sugar Walls 
“Come On’a My House” by Rosemary Clooney
“Angelina, Zooma Zooma” by Louis Prima
Southern Culture on the Skids-“8 Piece Box”
“You’re the Cream in my Coffee.”
“Mama’s Doughnut” – Spark Plug Smith/Tallahasse Tight. I’m not sure what it’s exactly about, but it’s certainly not about food.
Banana in Your Fruit Basket, Bo Carter
Your Biscuits are Big Enough for Me, Bo Carter
Let Me Squeeze Your Lemon, Charlie Pickett
Sam the Hot Dog Man, Lil Johnson
Nobody in Town Can Bake a Sweet Jelly Roll Like Mine, Bessie Smith
I Want Plenty of Grease in My Frying Pan, Margaret Carter
It Ain’t the Meat (It’s the Motion), The Swallows
Every one of those songs is about exactly what you think it’s about.
About two and a half minutes.
The Archies-Sugar, Sugar
The Candy Man can is either about candy or drugs, depending on your point of view
OTOH, the Grateful Dead song Candy Man is definitely not about candy.
They have Camel Walk as well.
