Preheat the oven to 350°F. Line a 9x5 loaf pan with parchment paper so there is an overhang or grease well with cooking spray.
In a large bowl, use a fork to mash the bananas removing as many lumps as possible. Add the eggs, oil, milk, and almond extract to the bananas and whisk to combine.
In a separate medium bowl, whisk the flour, sugar, baking powder, and baking soda together, then stir the dry ingredients into the wet ingredients. Fold in the sliced almonds.
Pour the batter into the pan and bake for 45-50 minutes, or until a toothpick comes out clean. Leave the bread in the pan for 10 minutes, then carefully remove from the pan to cool on a wire rack. Let cool completely before preparing the glaze.
To make the glaze, whisk the powdered sugar, milk, and almond extract together in a small bowl. Drizzle the glaze over the top and sprinkle with extra sliced almonds.
