"Hostess" Thor
Thor hosted a few of the Hostess one-page comics in the Bronze Age.

The mighty Thor swung his hammer for justice - and snack cakes - during his brief Hostess ads. Major Asgardians such as Sif, Loki, Volstagg, and Hela popped up, as did other unique threats from worlds beyond.
Thor In "The Ding-A-Ling Family"

Led by Grandma Ding-a-Ling, this family of outer space rednecks (Ma, Pa, Auntie, Sister, Brother, and Cousins Bee and Bye) appeared out of nowhere to battle Thor and the Asgardians. Despite Thor and Volstagg fighting mightily, it was Sif's plateful of Hostess Fruit Pies that won over the dumber family members and ended the Ding-a-Ling cosmic threat.
Loki
Returning from a battle, Thor finds his people worshiping a new face on the throne. Learning that Odin's usurper demanded tribute of Hostess Cupcakes, Thor deduced Loki was the mystery god, and quickly ended the trickster's reign.

A monster capable of reflecting any attack back at its opponent, the monstrous Ricochet became embroiled in a battle with Thor. Hurling Hostess Fruit Pies at his foe, the Asgardian sated its appetite and sent Ricochet back to its home planet.
"Good Overcomes Evil" Creature
Outfitted in a golden armor, a human-like figure battled Thor at the mental commands of a hidden foe. Sensing the disruption, Hela informed Thor and presented the armored being Hostess Fruit Pies - thus snapping the hold of evil and ending the fight.
