If you're using frozen berries, consider tossing them in a light dusting of flour before adding them to the batter. This can help prevent them from sinking to the bottom of the loaf.
Every oven can vary slightly. It's a good idea to start checking the bread for doneness around the 55-minute mark to prevent over-baking.
Allowing the bread to cool fully before slicing will give it the best texture and will make slicing easier.
When combining the wet and dry ingredients, mix just until incorporated to avoid overmixing. Overmixing can lead to a denser bread.
If you don't have buttermilk on hand, you can make a quick substitute by adding 1 teaspoon of lemon juice or white vinegar to a ½ cup of regular milk. Let it sit for 5-10 minutes, and it's ready to use.
This bread pairs beautifully with a light glaze made from powdered sugar and a bit of orange juice or with a spread of cream cheese.
