Can I use a muffin tin to slow my dog's eating

The raised walls between cups physically limit how much kibble a tongue or muzzle can gather in one movement, which is exactly the same principle a purpose built slow feeder bowl uses. A standard twelve cup tin comfortably spreads a small to medium meal across enough separate sections to make a real difference to pace.

A metal tin with some weight to it stays in place better than a lightweight silicone one, which can slide or flip if a determined dog pushes at it. Placing the tin on a non slip mat and using a size appropriate for the dog, standard size for most dogs and a mini muffin tin for very small breeds, both help.

A muffin tin is not designed as a pet product, so edges can occasionally be sharper than a purpose built slow feeder bowl, and it needs the same thorough washing after each use as any other food container to stay hygienic.

A muffin tin also works well for a wet food or mixed meal, spooning a small portion into each cup rather than leaving it as one large pile, though the cups will need a more thorough scrub afterward than they do with dry kibble alone, which is worth factoring in when deciding whether it suits a particular daily routine. Silicone tins are dishwasher safe in most cases, which makes the extra cleaning involved with wet or mixed food considerably less of a chore than hand washing every single cup after each meal.
