Preheat your oven to 350°F (175°C) and line an 8x8 baking dish with parchment paper.
Add the butter to a small saucepan and warm over medium heat, stirring frequently. Allow the butter to continue to melt over medium heat until it develops a nutty flavor and deepens in color (about 5-8 minutes). Remove the pan from the stove and let the butter cool.
In a large bowl, mix together the cooled butter, mashed bananas, Zen Basil seeds, eggs, maple syrup, vanilla extract, almond extract, and yogurt until combined.
Add the almond flour and baking powder to the wet mixture, mixing until fully combined.
Fold in the sprinkles, then pour the batter into the prepared baking dish, spreading it evenly.
Bake in the preheated oven for 30-35 minutes, until the top is golden and a toothpick inserted into the center comes out clean. You may need more time depending on your baking dish and the ripeness of the bananas.
Allow the blondies to cool, then slice into 8 squares and enjoy!
