Preheat oven to 350 degrees Fahrenheit and lightly grease or line a 9 x 5 inch loaf pan with parchment paper and set aside.
In a large microwave safe bowl, melt the butter in 30 second increments until fully melted. Set aside to cool.
Add the brown sugar and sugar to the melted and cooled butter and mix until the sugar is fully incorporated.
Add the mashed bananas, egg, milk, vanilla and almond extracts to the butter and sugar mixture and stir to mix well.
Add the flour, baking powder and sea salt to the bowl and mix until just combined. A few streaks of flour showing is just fine, since we're going to mix one more time after adding the sprinkles. Don't overmix the batter.
Gently fold in the sprinkles. A few quick turns should do it.
Pour the batter into the prepared loaf pan and generously cover the top of the bread with more sprinkles.
Bake at 350 degrees Fahrenheit for 60-65 minutes, until a toothpick inserted in the center comes out clean. The top of the bread will be brown and likely cracked open on top.
Allow the banana bread to cool in the pan for 30 minutes before slicing, so it can set up.
Store bread in an airtight container for 3-4 days or freeze for up to 3 months.
Notes
Use very ripe or black bananas for the best flavor and sweetness.
Let melted butter cool slightly before mixing in the additional ingredients.
Stir batter gently and avoid over-mixing to keep the bread tender.
Use jimmies (sprinkles) to prevent color bleeding.
Bread is done when a toothpick inserted in the center comes out clean. The top should be golden brown and likely cracked open.
Cool bread in the pan for 30 minutes before slicing to help the loaf set up and slice clean.
Better the next day. The flavor of this bread deepens and the texture becomes even softer after sitting overnight.
