Instructions

1. Heat the oven to 250°F. Line a sheet pan with parchment paper or a silicone baking mat.
2. Combine the milk powder, flour, cornstarch, corn powder, sugar and salt in a medium bowl. Toss to mix. Add the melted butter and toss, using a spatula, until the mixture starts to come together and form small clusters.
3. Spread the clusters on the lined sheet pan and bake for 20-25 minutes. The crumbs should be sandy, but still clumped together, just starting to brown around the edges, and your kitchen should smell like buttery heaven. Cool the crumbs completely. The crumbs will keep in an airtight container in the fridge or freezer for up to 1 month.
