These muffins are meant for the table where breakfast and supper sometimes need the same kind of practical baking: something warm, sturdy, and kind to humble ingredients. The oats keep them from tasting empty, and the brown sugar rounds them out without turning them into cake.

They are especially good on chili night or with a bean supper, when a plain slice of bread would not feel quite finished.

Ingredients

Dry ingredients

  • 2 cups old-fashioned oats
  • 2 cups all-purpose flour
  • 3/4 cup brown sugar
  • 2 tablespoons baking powder
  • 1 teaspoon cinnamon
  • 1 1/2 teaspoons kosher salt

Wet ingredients

  • 2 large eggs
  • 2 cups milk
  • 1/2 cup melted butter
  • 1 teaspoon vanilla extract

Method

  1. Step 1. Heat the oven to 375 degrees Fahrenheit and grease the muffin cups well.
  2. Step 2. In a large bowl, whisk together the oats, flour, brown sugar, baking powder, cinnamon, and salt until the leavening is spread evenly.
  3. Step 3. In a second bowl, whisk the eggs, milk, melted butter, and vanilla until fully blended.
  4. Step 4. Pour the wet ingredients into the dry and fold just until the flour disappears; the batter should look thick and scoopable, not beaten smooth.
  5. Step 5. Divide the batter among the muffin cups, filling them about three-quarters full.
  6. Step 6. Bake for 18 to 22 minutes, until the tops spring back and the edges are golden.
  7. Step 7. Cool the muffins in the pan for 5 minutes, then move them to a rack so the bottoms do not steam and soften.

Equipment

  • mixing bowls
  • whisk
  • 18-cup muffin pan or two standard muffin pans

Storage & safety

Keep cooled muffins covered at room temperature for 1 day or refrigerate for up to 4 days. Freeze for longer holding and warm before serving if you want the crumb soft again.

Safe minimum internal temperature: 160°F

Cool the muffins fully before sealing them up so trapped steam does not make them sticky.

Do not taste raw muffin batter because it contains raw flour and eggs.

Troubleshooting

The muffins baked up tough
The batter was likely overmixed. Next time fold only until the dry ingredients disappear and stop.
The muffins seem bland with supper
Serve them warm with butter and use the full salt amount because oats and flour swallow seasoning quickly.

Recipe rescue notes

The tops softened overnight

Likely cause: The muffins were stored while still warm.

Fix: Warm them a few minutes in the oven to bring back some life to the crust.

Next time: Cool the muffins fully on a rack before covering them.

Substitutions

Milk
Use buttermilk. — The crumb will be a little tangier and slightly softer, which works especially well if you plan to serve them with chili or soup.

Carryover / Next Meal Ideas

Next-morning peanut butter muffins

Split and warm leftover muffins, then spread with peanut butter for a quick breakfast that still feels substantial.

  • Thin apple slices tuck in well if you want a little fruit with the peanut butter.
