Econo Bran Muffins are a type of muffin that were very briefly seen in "A Glass of Warm Ed," when Ed goes sleepwalking and leaves litter all over the Cul-de-Sac. Edd and Eddy spotted the box of muffins in the lane. Edd and Eddy seemed surprised that Ed was able to eat a whole box of them. Eddy claimed that he wanted to go see Ed get heartburn (Edd said, "This could be dangerous, Eddy.").
- It is unknown which house Ed found the box in, or if he even got it from someone's house.
- In "O-Ed Eleven," a box in Eddy's Brother's room reads, 'Econo Beans'. It is possible that there is an Econo Company that manufactures food.
- "Econo" refers to it being an "economy size", which means that it has a lot of food for a low price. Bran helps to clean out the digestive tract, which is why it was apparently dangerous that Ed had eaten an economy size box of bran muffins, seeing as he had been eating everything else in the Cul-de-Sac.
