Preheat oven to 350°F (180°C) and grease a loaf pan.
In a bowl, whisk together dry ingredients.
In another bowl, whisk wet ingredients until smooth.
Gently fold wet ingredients into dry, avoiding overmixing.
Pour batter into prepared pan, sprinkle toppings if desired.
Bake for 45-55 minutes, or until a toothpick inserted comes out clean.
Let cool in the pan for 10 minutes, then transfer to a wire rack.
Slice and enjoy!
