Preheat the oven to 350°F (175°C). Line a small baking dish with parchment paper, leaving an overhang to lift the bars out later.
In a large bowl, whisk together the quick oats, brown sugar, granulated sugar, chocolate protein powder, salt, and cinnamon until evenly combined.
Stir in the slivered almonds and milk chocolate chips so they are distributed through the dry mixture.
In a small microwave-safe bowl, combine the almond butter, honey, and coconut oil; microwave in short bursts until melted and smooth, stirring between bursts. Stir in the vanilla extract and applesauce.
Pour the wet mixture into the dry ingredients and mix thoroughly until everything is evenly coated and holds together when pressed.
Transfer the mixture to the prepared baking dish. Press firmly and evenly into the pan, compacting the mixture and pushing it against the sides.
Bake for 33–35 minutes, until the sides begin to darken and pull away slightly from the pan.
Allow the bars to cool completely in the pan, then lift out using the parchment overhang and slice into 10 bars.
