Preheat oven to 350°F (175°C). Line your loaf pan like someone who remembers parchment paper exists.
Mash bananas in a big bowl. Add oil, sugar, milk, and vanilla. Stir like you’re making life choices.
In another bowl, whisk flour, baking soda, salt, and cinnamon. No clumps, no stress.
Combine dry mix with the wet stuff. Stir gently—this isn’t CrossFit.
Fold in blueberries with care. Don’t smash the poor things; they’ve been through enough.
Pour batter into your pan. Level the top like you have inner peace.
Bake for 50 minutes, or until the top looks golden and a toothpick comes out with just banana glory.
Cool for 10 minutes, then remove from pan. Try not to eat the whole thing in one standing.
