Hey there, Phoenix! You might be able to find a loaf pan designed for this exact scenario by searching for "mini loaf pan" or "half loaf pan" on Google. Another thing you might consider is using a hotel pan which is commonly used in a steam table at a buffet or for keeping food warm during dinner service at a restaurant — I think a "ninth pan" might work well for what you're looking to do here. We hope this helps and happy baking!
