Stuffed Cinnamon Streusel Muffins - #MuffinMonday

It has been so long since I have baked muffins that my poor muffin tins had made their way to the back of my cupboard under things I never use. I had to get a flashlight to find them. It has just been one thing after the next but I was happy to take the tins out of faux-retirement for these delicious muffins. These are absolutely the best muffins that I have ever made. 

I used a recipe from King Arthur Baking and made some slight changes. Nothing major. I loved these so much that I am thinking of making another batch tomorrow. My friend flies out on Wednesday and I think these muffins would make her ten-hour flight sweeter. 

As always, scroll down to see what the other bakers whipped up today. 

Stuffed Cinnamon Streusel Muffins 
Yield: 12 


106 grams (1/2 cup) brown sugar 
42 grams (3 tablespoons) melted butter 
4 teaspoons cinnamon
71 grams (1/3 cup) brown sugar
60 grams (1/2 cup)  flour 
22 grams (1/4 cup) rolled oats
1/2 teaspoon cinnamon 
3 tablespoons softened butter 
210 grams (1 3/4 cup) all purpose flour 
45 grams (1/2cup) rolled oats
150 grams (3/4 cup) sugar
14 grams (2 tablespoons) cornstarch
1 tablespoon baking powder
1/2 teaspoon salt 
1/4 teaspoon nutmeg 
3/4 cup milk 
1/2 cup oil 
2 eggs


Preheat oven to 400 F. Line a 12 cup capacity muffin pan with liners. 

Mix together the filling ingredients and set aside for at least 15 minutes to thicken. 

Make the streusel by mixing together sugar, flour, oats, and cinnamon. Next mix in the butter until the mixture is crumbly. 

Time to work on the muffin batter!

Whisk flour, oats, sugar, cornstarch, baking powder, salt, and nutmeg. 

In a separate container, whisk together milk, oil, and eggs. 

Add the liquid ingredients to the dry ingredients. Stir gently until just combined and there are no streaks of flour. 

Scoop scant two tablespoons into each muffin well. 

Next, add two teaspoons of the filling then top with the remaining batter. 

Sprinkle on the streusel. Use it all up, it's delicious.

Bake 20 - 25 minutes until the tops are golden. You can do the toothpick test but be careful that you're not sticking sticky filling. 

Cool and enjoy. 

  • Don't skip the liners for these muffins! Some of the filling could seep to the bottom of the tin and cause them to stick. Ask me how I know.
