Preheat oven to 350°F (175°C). Grease and line a loaf pan.
In a large bowl, mix all wet ingredients until smooth.
In a separate bowl, whisk together all dry ingredients.
Gently fold dry ingredients into wet just until combined.
Pour batter into pan and smooth the top.
Bake for 55–65 minutes, checking with a toothpick for doneness.
Cool in pan 10–15 minutes, then transfer to a rack to cool completely before icing.
Beat all frosting ingredients in a stand mixer until smooth, light, and fluffy.
Spread frosting generously over cooled loaf.
Place loaf in fridge for 2+ hours for icing to set before slicing.
