Sanitize all work areas, cutting boards, equipment and sinks used in the preparation of this recipe.
Place disposable baking pans onto parchment lined sheet trays.
Combine muffin batter and pumpkin puree into a stainless-steel bowl.
Mix together until thoroughly combined and smooth.
Using a scale, portion 7 oz, by weight, of batter into each pan.
Evenly distribute 1 oz, by weight, of Crumble over the top of each loaf.
Place loaves into a 325°F oven, high fan. Bake for 20 minutes.
Carefully rotate the pans to ensure even cooking. Continue baking until golden brown on top, and a cake tester comes out clean when inserted into the center of a loaf, about 15-20 minutes.
Remove from the oven. Cool completely.
Transfer to clean airtight food storage containers. Do not stack. Cover, label, date and store for service.
