Did you notice that all my cupcake recipes yield 24? With so many cupcakes (is 24 really a lot?), you might, theoretically, have a few left over. Those little leftover treasures are the secret behind my most brilliant invention: the crumb. Crumbs consist of either an unfrosted cake or an unfrosted cupcake broken down and treated with additional flavoring. In most cases, you’ll be using cupcakes, which aren’t all that sweet on their own and are thus the ideal blank canvas. You’ll find the vanilla-based version to be the most versatile crumb of the three I’ve included. You can add your favorite spices to tailor it to your taste; just don’t add more than 2 teaspoons of the spice you choose, or it will overpower the cake you’re baking.

Ingredients

　　2 tablespoons coconut oil

　　1/4 cup agave nectar

　　1/2 teaspoon salt

　　In a medium bowl, use your hands to crumble the cupcakes into small, fine bits. Add the oil, agave nectar, and salt to the crumb. Using a rubber spatula, fold together the ingredients until thoroughly combined. Store in an airtight container at room temperature for up to 4 days. For longer shelf life, store in the freezer for up to 3 weeks.
