Celebrate National Oatmeal Muffin Day 🧁 in the Obscure Holiday Calendar app with themed artwork, reminders, and quick-share cards.

Overview

National Oatmeal Muffin Day, observed every December 19, celebrates a baked good that sits right between a bowl of oatmeal and a cupcake — and a name whose own history is older and stranger than the muffin itself.

Why it matters: National Oatmeal Muffin Day, observed on December 19, is a small reminder that even the most familiar bakery-case item usually has a name with a much older, murkier backstory than anyone stops to ask about.

Origin and story

Oatmeal is considered "heart-healthy" because its soluble fiber can help lower LDL cholesterol levels, making oatmeal muffins a guilt-free indulgence.

The word "muffin" is believed to derive from the Low German "muffen," meaning little cakes, first appearing in English print in 1703.

Ways to celebrate

The word "muffin" is centuries older than most people would guess, and nobody's entirely sure where it actually came from.

A word first spotted in 1703

"Muffin" first appears in English print in 1703, spelled "moofin," and recipes for muffins were being published in British cookbooks as early as Hannah Glasse's 1747 "The Art of Cookery." The leading theory traces the word to the Low German "muffen," the plural of "muffe," meaning a small cake or pastry. A competing theory ties it instead to the Old French "moflet," meaning soft or tender bread — nobody has definitively settled which is correct.

Why oatmeal, specifically

Oats are a whole grain, and diets high in whole grains have been linked to a reduced risk of colorectal cancer. Oatmeal's soluble fiber can also help lower LDL cholesterol, which is part of why an oatmeal muffin gets marketed as the "healthier" bridge between a bowl of oatmeal and a frosted cupcake — even though, structurally, a muffin is a quick bread leavened with baking powder or soda, not a cake at all.

Ways to mark the day

  • Bake a batch of oatmeal muffins with a mix-in: blueberries, bananas, raisins, or cinnamon.
  • Compare the texture of a true quick-bread muffin to an actual cupcake side by side.
  • Share the "moofin" 1703 spelling with someone who assumes muffins are a modern invention.

Did you know?

Unlike the frosted cupcakes they resemble, muffins are traditionally leavened with baking powder or baking soda rather than yeast, which is part of why they bake so quickly.
