This big, bakery style Maple Walnut Muffin is the perfect size for one person. Baked in a ramekin and topped with a buttery, crumbly cinnamon streusel topping, this tender muffin is perfect for breakfast or dessert. Ready in minutes!

If you ask me what the ideal breakfast is, I'd say muffins. The aroma of freshly baked muffins - or in this case, a freshly baked maple walnut muffin is undeniably heavenly. Give me a hot cup of coffee to go along with a perfectly sweet, tender muffin and life completely slows down.
A single muffin is perfect, especially if you're cooking for one or two.
A Muffin
Yes, this is one muffin but it's a good-sized muffin. Not too small, not too big. In fact, sharing is completely optional.

Although maple syrup season runs from February until late March, I always associate maple with fall. Maybe it's because we typically use maple syrup in fall recipes like my small batch pumpkin spice granola and in the maple whipped cream I use to top my sweet potato pie for one.
Needless to say, maple syrup is the perfect addition to this muffin recipe.

I bake this maple walnut 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.
Pro Tip: 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.

I love these recipes. When you say ramekin, what size are you talking? I have several sizes of ramekins.
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.
