Preheat the oven to 300°F (150°C). Line a large baking sheet with parchment paper.
In a large bowl, combine the oats, sliced almonds, pecans, and salt.
In a separate bowl, whisk together the melted coconut oil, maple syrup, egg white, vanilla extract, and almond extract until well combined.
Pour the wet ingredients over the oat mixture and stir until everything is evenly coated.
Spread the mixture onto the prepared baking sheet in an even layer. Press it down lightly if you'd like larger granola clusters.
Top with the crumbled cake scraps.
Bake for 35–40 minutes. At the 20-minute mark, remove the pan from the oven and gently stir and flip the granola. Return to the oven and continue baking until golden and fragrant.
Let the granola cool completely on the baking sheet. Avoid stirring while it cools to encourage clusters to form.
Once cooled, stir in the sprinkles, white chocolate chips, and hemp seeds.
Store in an airtight container at room temperature for up to 2 weeks.
