If you ask me, I think the ideal breakfast is a muffin. The aroma of freshly baked muffins - or in this case, a freshly baked maple walnut muffin is undeniably heavenly. Add a hot cup of coffee to go along with it and life completely slows down.

Why This Recipe Works

  • A single muffin is perfect, especially if you're cooking for one or two.
  • Although this recipe yields 1 muffin, it is a good-sized muffin. Not too small, not too big.
  • This maple walnut muffin is so easy to make and absolutely delicious. It's tender and perfectly sweet.

Ingredient Notes

See recipe box below for ingredient amounts and full recipe instructions.

  • Flour: I use all-purpose flour or plain flour.
  • Brown sugar: You can use either light or dark brown sugar. If you don't have brown sugar, you can make your own with our homemade brown sugar recipe.
  • Baking powder: Helps the muffin rise.
  • Salt, cinnamon, maple syrup and vanilla extract: Use all four of these ingredients for flavor.
  • Milk: Milk adds plenty of moisture and lightens up the crumb.
  • Butter: This ingredient adds moisture and flavor.
  • Sour cream: Just a touch of sour cream keeps the muffin extra moist. I highly recommend it!
  • Egg yolk: Just one egg yolk is all you need to make this big bakery-style muffin. See below for ways to use leftover ingredients.
  • Walnuts: I love using chopped walnuts in this muffin, but you can use chopped pecans or leave nuts out completely.

For the streusel topping

  • Flour: A small amount of all-purpose flour helps bind the mixture together and give it a crumbly texture.
  • Sugar: I use granulated sugar in the topping. It helps the streusel topping crisp up slightly when the muffin is baked.
  • Cinnamon: This is an optional ingredient but works well in this streusel. Its only function is flavor and can be left out completely if desired.
  • Walnuts: For added crunch. Feel free to leave out the nuts if you'd like.
  • Butter: This ingredient helps create a crumbly texture by adding moisture. Without the fat from butter, the streusel mixture would be very dry after baked.

Frequently Asked Questions

What Size Baking Dish Should I Use To Make A Maple Walnut Muffin?

I bake this muffin in an 10-ounce ramekin that measures 4-inches in diameter and is approximately 1 3/4-inches tall. Use a baking dish of similar size or slightly larger for best results. If you would like additional information on the cooking and baking dishes I use in our “recipes for one”, please visit our FAQ page.

Expert Tips

  • Many ramekins don’t have the size printed on them. Because of this, it can be hard to know exactly how large (or small) yours is. The best way to measure the size of your ramekin is to fill it with water and pour the water into a measuring cup.
  • You can also use mini loaf pans that also hold about 8 to 10-ounces. If you happen to have smaller ramekins, use those and divide the batter between them.
  • This maple walnut muffin recipe will yield one very large muffin.

    1. Hi Kathy, in the recipe post I suggest using a 10-ounce ramekin which measures 4-inches in diameter and is approximately 1 3/4-inches tall. Use a baking dish of similar size for best results.
