Sleep or Cinnamon? I'd pick cinnamon

If there's a recipe and it says cinnamon swirl, I'm there. This quick bread is wonderful - it's soft and moist, and best of all - lots of cinnamon. I love that it comes together without softening butter which I often forget to do. it was perfect for a Sunday morning breakfast where we all ate around the same time... well... one of us didn't eat, she never really eats breakfast. Why do that when there's more time for sleep? The rest of us enjoyed it, quite a bit in fact!

Cinnamon Swirl Quick Bread
Ingredients
Bread Batter:
¾ cup granulated sugar
½ cup milk
½ cup sour cream
⅓ cup vegetable or canola oil
1 large egg
1 teaspoon vanilla extract
1 ¾ cups all-purpose flour
1 teaspoon baking powder
½ teaspoon baking soda
½ teaspoon salt
Cinnamon Sugar + Topping:
6 tablespoons granulated sugar
2 ½ teaspoons ground cinnamon
1 tablespoon melted butter

Instructions
Preheat the oven to 350 degrees F. Grease an 8 1/2-X4 1/2-inch loaf pan with nonstick cooking spray. Optional: line pan with parchment and grease parchment.
For the batter, in a large bowl, add the sugar (3/4 cup), milk, sour cream, oil, egg, and vanilla. Mix well.
Add the flour, baking powder, baking soda and salt. Mix until no dry streaks remain (don't over mix).
For the cinnamon and sugar, in a small bowl, mix the granulated sugar (6 tablespoons) and cinnamon together until well-combined.
To assemble, spread half of the batter in the prepared loaf pan. Sprinkle 1/4 cup of the cinnamon/sugar mixture over the batter.
In large spoonfuls, dollop the remaining batter over the cinnamon and sugar. Spread evenly.
Sprinkle remaining cinnamon and sugar (about 2 1/2 tablespoons) evenly over the top of the batter.
Draw a butter knife through the batter in three diagonal lines starting from one corner in a down-up-down pattern and then repeat the pattern one more from an opposite corner so the lines cross each other (see the pictures in the post for a visual). Don't over swirl the batter. It just needs a few slashes for optimal cinnamon and sugar swirling.
Drizzle the melted butter across the top of the bread.
Optional: the batter fills an 8 1/2-X4 1/2-inch pan about 2/3 full. If you live at high elevation or are worried about any of the cinnamon topping dripping into your oven while baking, place the loaf pan on a sheet pan to bake. FYI: I live at 2,500 feet elevation, and the bread doesn't overflow/drip in my oven.
Bake the bread for 50 to 55 minutes. The bread won't dome as much as other quick breads and may be relatively flat across the top, but a toothpick inserted in the center should come out clean or with moist crumbs. Add additional time, if needed.
Let the bread cool for a few minutes in the pan and then gently turn out (or lift parchment paper to remove) and let cool completely on a cooling rack.
Because the top of the bread will have some crunch to it, for neat slices, use a sharp serrated knife and gently slice the corner edge of the bread before drawing the knife across to cut all the way through each slice.
