Not your ordinary muffin, these muffins are sinfully delicious with a luscious, moist, rich cinnamon filling then crowned with a streusel topping and a sweet glaze. These would be a wonderful way to start your Easter morning.
This Simply Sinful Cinnamon Muffin recipe is one of many great recipes on the King Arthur Flour website. I’ve posted before how much I love the King Arthur Flour Fudge Brownies and their Double-Dutch Dark Cocoa. So when King Arthur invited me to partner with them, I chose to bake this cinnamon muffin recipe because I’ve been wanting to try their Baker’s Cinnamon Filling mix.
In addition to the Baker’s Cinnamon Filling, King Arthur Flour also sent me a coupon for a free bag of flour at the supermarket and a cookie scoop. If you’re not using a large cookie scoop to portion out your muffins, you really need to get one and give it a try. A scoop makes it so much easier.
This recipe make huge, pretty, almost overflowing muffins. I even put a tray underneath the muffin pan just in case they did overflow. Unlike other cinnamon fillings, this filling stays thick and moist. I only used a portion of the bag they sent me, so I’m looking forward to using it in some cinnamon rolls in the near future.
I thought the topping needed to be sweeter, but my daughter said, “No they’re perfect. I wouldn’t change a thing.” If you’d like to bake these perfect muffins at home, King Arthur Flour has also offered to giveaway a cookie scoop, a bag of Baker’s Cinnamon Filling, and a coupon for a free bag of flour at the supermarket to one lucky Barbara Bakes’ reader. Details on how you can enter the giveaway are at the bottom of the post.

- ¼ cup rolled oats
- ½ cup King Arthur Unbleached All-Purpose Flour
- 3 tablespoons soft butter

- ½ cup Baker’s Cinnamon Filling mix*
- 3 to 4 tablespoons water
Batter
- ½ cup 1 stick butter, melted
- ¾ cup milk room temperature
- 2 large eggs
- 1 ¾ cups King Arthur Unbleached All-Purpose Flour
- ½ cup rolled oats
- 2 tablespoons Signature Secrets r Culinary Thickener or cornstarch
- ¾ cup granulated sugar
- 1 tablespoon baking powder

Instructions
- Preheat your oven to 400°F. Line a 12-cup muffin pan with cupcake papers, or grease it lightly.
- Prepare the topping by mixing the ingredients together until crumbly. Set aside.
- Prepare the filling by mixing the Baker’s Cinnamon Filling with enough water to make filling with a soft, pudding-like consistency. Set it aside.
- To make the batter: In a large bowl, whisk together the melted butter, milk, and eggs. In a separate bowl, whisk together the dry ingredients, including the chips. Add the dry mixture to the liquid, stirring just until combined.

Oh my goodness, yummy cinnamon struesel muffins. Perfect with morning coffee. Looking forward to trying another of your amazing recipes. Thanks so much.

These remind me of the most delicious Cobblestone Muffins at Panera – one of my favorites! To do that I would omit chips and add chopped apples. Will definitely try.

I’ve always wanted to try their cinnamon filling but just haven’t ordered it. It would be great to win it.

I remember reading that if you add a little flour to your cinnamon roll filling, it will stay gooey instead of being runny. Makes sense to me. I’ll try these, because cinnamon rolls are one of my Achilles heels, and anything that will make them easier is a win-win for me.

I love King Arthur’s website and recipes too-in fact I made these yummy muffins for the first time last year. They are our favorite muffin now. Yours look awesome Barbara, and are calling my name so I think I need to go make more!
Karen
Oh yum! I so need to know where you got the bluebird mugs too!
Barbara Schieving
Thanks Karen – I fell in love with the little bluebird while shopping at the grocery store and he had to come home with me. He was all by himself at Harmons and really needed a good home. 😉

I love King Arthur Flour! I’m a Vermont native, so when I go back to visit my parents I get to visit their store – it is sooo dangerously awesome. They have a great bakery there, too, so it’s tempting for both my stomach AND pocketbook.

Those muffins look crazy good! Better than a plain old cinnamon roll!
