I scrape the beautiful, fragrant batter into my prepared loaf pan and smooth the top with a spatula. I give the pan a few gentle taps on the counter to release any large air bubbles. Into the oven it goes! I bake it until a toothpick inserted into the very center comes out clean, which usually takes 50-60 minutes. I start checking at 50 minutes. The top will be a gorgeous golden brown, and the smell will be utterly intoxicating. I let the loaf cool in the pan on a wire rack for 15 minutes before using the parchment sling to lift it out to cool completely before glazing.
Pro Tips for Best Results
The single biggest factor for moisture is the sour cream or Greek yogurt. I tested this with milk, buttermilk, and sour cream. Sour cream won by a landslide for creating a dense, velvety, and supremely moist crumb that stays that way for days. Full-fat is best here. If you only have yogurt, use a whole-milk, plain variety for similar results.
Creaming the butter and sugar properly is the secret to a good rise and texture. I used to rush this step, but I learned the hard way that a quick mix leads to a dense, heavy loaf. Now, I set a timer for 3 full minutes of beating on medium speed. You’ll see the mixture transform in color and texture, becoming almost like a fluffy frosting. This aeration is crucial.
Do not overmix the batter once the flour is added. As soon as you no longer see dry flour streaks, stop the mixer. I use a spatula to do the final few folds by hand. Overmixing develops the gluten in the flour, which leads to a tough, rubbery texture instead of the soft, tender crumb we’re after. A few small lumps are perfectly fine and will bake out.
Common Mistakes to Avoid
My first loaf was disappointingly dense because I used cold eggs and sour cream straight from the fridge. They caused the beautifully creamed butter and sugar to seize up and become grainy, and the batter never emulsified properly. This results in a heavy, sunken cake. Now, I leave all my dairy and eggs on the counter for at least an hour before I start. It makes a world of difference.(See the next page below to continue…)
