Heat oven to 350 F.
Combine sugars, waffle mix and sprinkles (optional) in the bowl of a stand mixer using the paddle attachment. Turn on low speed until combined.
Add the extracts and oil and turn on low until ingredients combine until small clumps are formed. Stop once the mix starts to clump.
Spread clumps of crumble onto parchment-lined baking sheet and bake in preheated oven for 20 minutes.
Break apart any large crumbles halfway through baking. Crumble will come out of the oven soft but will crisp up as it cools.
Crumble can be stored in the fridge in a airtight container for two weeks or in the freezer for up to a month.
