Muffining our way out of the Summer

We are about to travel for the last time this summer and it's been a busy summer for travel! This time it's to Wisconsin, so not too long of a ride and no camping required when we get there. Not a bad way to end things up this summer. I try to bring some breakfasty things since Nicholas and I are early risers. It's been a crazy could of months and I just struggled this time to figure out what to make, decided these muffins were it. Also some banana bread muffins because everyone loves those... I'm pretty sure everyone is going to love these too, oh, how do I know? Well... it's possible two didn't fit in the container and well, sometimes you just have to sample your work, so that's what I did and I'm glad I did, these are going to be winner muffins! Heated up with a little butter on them, oh man, delicious! I forgot the glaze too. I was laying in bed last night and realized I forgot the glaze, I don't think you need it. Maybe you want it? Sure! Go for it, but need? Meh... these are good enough without it.

Sour Cream Coffee Cake Muffins
Filling & Topping:
⅔ cup all-purpose flour
⅔ cup packed light brown sugar
2 ½ teaspoon ground cinnamon, divided
¼ teaspoon salt
4 tablespoon unsalted butter, melted and cooled
Muffin batter:
2 cups all purpose flour
2 teaspoon baking powder
½ teaspoon baking soda
½ cup packed light brown sugar
⅓ cup granulated sugar
½ teaspoon salt
2 large eggs, at room temperature
½ cup full fat sour cream, at room temperature
2 teaspoon pure vanilla extract
⅓ cup sunflower oil
¾ cup whole milk, at room temperature
Glaze:
½ cup powdered confectioner's sugar
1 tablespoon light (half & half) 10% cream

Make the filling/topping. Combine flour, brown sugar, 2 teaspoons of cinnamon and salt until blended. Add the melted butter and stir it in until it evenly blended and the mixture forms clumps. To make the filling, take ¾ cup of this mixture and place in a separate bowl and stir in the other ½ teaspoon of cinnamon. Cover the bowl with the rest of the mixture and set it aside for topping.
Make the muffin batter. Sift flour, baking powder and baking soda into a large bowl. Add brown sugar, granulated sugar and salt and whisk to blend well. Press out any lumps of brown sugar so the mixture is well combined.
Combine eggs, sour cream, vanilla, oil and milk in a medium bowl and whisk until completely smooth.
Pour the wet ingredients into the bowl with dry ingredients and gently fold together to combine. Stop right as the batter is uniform, being sure to reach down to the bottom to pull up any pockets of flour. Cover the bowl and set aside to rest for 30 minutes while the oven preheats.
Preheat the oven to 425°F for tall peaked muffin tops. Line a standard 12-cup muffin pan with paper liners. Or for extra large muffins, make 10. If making 10 then you definitely need 2 pans so you can space out the muffins every other cup since they will spread out to make large muffin tops.
Use a 1.5 oz scoop to portion batter and add one scoop to each muffin cup. Sprinkle 1 tablespoon of cinnamon filling evenly over top, then cover with batter so the cups are full. Pile the crumb topping on (really pile it on!). Don't be shy with the topping because it will spread out as the muffins rise in the oven. Bake for 5 minutes. Then, with the oven door still closed, reduce the oven temperature to 350°F and bake for another 15 minutes. Let muffins cool for 5 minutes in the pan and then transfer muffins to a cooling rack. They're best served warm but also store really well and stay moist for days!
