Preheat oven to 350 degrees F.
Mix the egg, coconut sugar, Greek yogurt, applesauce, vanilla extract, and almond extract in a large bowl until fully combined.
Then, stir the flour, protein powder, and baking powder until fully combined.
Spread the batter into an 8x8-inch parchment-lined pan.
Optional - If using sprinkles, spread them evenly across the batter and gently press them so they stick.
Bake for 20 minutes.
Remove the bars from the oven and allow them to cool for 10 minutes. Then, pull the side of the parchment paper to release the bars from the pan. Cut and serve.
