Baking muffins in rv oven for the first time...gasp!

No gasp here:).
From what I've read an RV oven is one of the least utilised cooking appliance in the kitchen.

Yes to using a paver/ pizza stone or big box store 2-3 buck unglazed quarry tile( prolly the least expensive option;))and changing position of muffin tin to accommodate the heating elements cold spots. You can also line each tin with parchment paper or use the cupcake/muffin paper liners to cut down on burnt bottoms and clean up.

Chocolate muffins, ehh?
Got recipe?
