Ingredients
- 1 3/4 cups all-purpose flour
- 2/3 cup granulated sugar
- 1 teaspoon baking soda
- 1 1/2 teaspoons cream of tartar
- 1/4 teaspoon salt
- 2 large eggs
- 1 cup buttermilk
- 1/3 cup melted unsalted butter
- 1 teaspoon vanilla extract
- 1/2 cup granulated sugar
- 1 tablespoon ground cinnamon
About the ingredients
Method
- Preheat oven to 355F. Thoroughly grease 9x5 loaf pan with nonstick spray or butter; flour if feeling cautious. Keeps loaf intact when pulling out—trust me on this.
- Dry mix first: whisk flour, sugar, baking soda, cream of tartar, salt in medium bowl. Important to blend evenly here so lifting ingredients later is smooth.
- In separate bowl, beat eggs slightly. Add buttermilk, melted butter (cooled), vanilla. Whisk until combined but don't overbeat. Avoid rubbery texture.
- Pour wet into dry. Fold gently but thoroughly until no dry streaks remain. Batter should be slightly thick but pourable—not pasty.
- Mix cinnamon and sugar in small bowl. This is your swirl agent; more cinnamon amps aroma and creates beautiful ribbons inside loaf.
- Dollop about one-third batter into pan. Sprinkle 2 tablespoons cinnamon sugar evenly but don’t clump; spread with spoon if needed.
- Repeat layering: batter then cinnamon sugar twice more, ending with remaining cinnamon sugar on top for crust punch.
- Bake 55 to 60 minutes. Watch edges first—should pull away slightly from pan walls and crust shifts to a deep golden brown. Toothpick inserted near center comes out clean with maybe a few moist crumbs but no wet batter.
- Cool loaf in pan 10-15 minutes. This resting phase firms crumb enough for clean removal. Flip onto wire rack; cool fully before slicing or it’ll crumble and stick.
- Store wrapped at room temp up to 3 days or freeze sliced. Reheat gently—moisture comes alive with mild warmth.
Cooking tips
Chef's notes
- 💡 Mix dry ingredients first always—flour, sugar, cream of tartar, baking soda. Makes folding wet into dry smoother; avoids dense patches or clumps. Sift flour or whisk well to keep airy texture. Cream of tartar key for that snickerdoodle tang and lift. Swapping with lemon juice works but expect milder tang and slightly different rise. Butter should be melted and cooled to avoid cooking eggs early and heavier batter.
- 💡 Layer cinnamon sugar in thirds for those visible ribbons. Dollop batter then cinnamon mix, spread gently but evenly; clumps turn into overly sweet pockets. Repeat layering three times, finishing with a top layer of cinnamon sugar to get crust punch. Don’t mix swirl into entire batter or it sinks into bottom. Patterns form best if batter is thick but still pourable; too stiff and layers don’t settle well.
- 💡 Watch crust color closely past 45 minutes. Should pull slightly at edges away from pan, sound faint crackling. Toothpick test near center key—moist crumbs okay, no wet batter. Oven temps vary so check early, later, and multiple spots if unsure. Baking at 355F nudges caramelization without burning. Longer bake stretches to 60 minutes ensure center cooks without drying edges.
- 💡 Cool loaf in pan for about 10-15 minutes to let crumb firm. Flipping too early causes breakage, sticking mess. Then flip onto wire rack, full cool needed before slicing or crumb sticks and crumbles. Room temp rest also helps flavor develop. Wrap airtight for storage. Freeze slices if you want ahead; thaw at room temp or warm gently with care to avoid drying.
- 💡 Eggs lightly beaten only; overbeating tougher crumb, rubbery. Fold wet into dry gently for mix but no streaks; keep batter thick but pourable—not runny. Folding keeps gluten development moderate for tender bite. Pan prep important—grease with nonstick spray, then flour adds grip for loaf release. Deep crevices catch batter otherwise and cause tears on removal.
Common questions
Can I substitute baking powder?
No direct swap here. Cream of tartar plus baking soda gives lift and tang. Baking powder missing acid; flavor profile changes. Use lemon juice but expect minor rise and taste difference. Not recommended if aiming for similar crumb.
What if loaf cracks on top?
Normal but check oven temp first. Too hot, too fast cause cracks. Cooling rack placement also affects crust setting. Crackle around edges fine, signals baking progressing as moisture escapes. If big split, batter might be too thick or too much rising agent.
How to fix dense crumb?
Overmixing wet and dry triggers gluten. Mix dry well but fold wet gently. Check flour measure—packing flour too much densifies loaf. Also make sure melted butter is cooled off or eggs scramble. Let batter rest a few minutes before baking to relax gluten.
Can I use regular milk not buttermilk?
Use vinegar or lemon juice in milk, let sit 5 min before mixing. Provides acidity for cream of tartar reaction. Without acid, loaf tastes flat, texture heavier. Half and half or sour cream can work but adjust flour if batter seems wetter.
