Fat Daddio's 4.4oz Cube Silicone Baking Mold
Silicone molds carry lower concern and have no PFAS-typical coatings.
This food-grade silicone mold lacks nonstick or water-repellent coatings linked to PFAS. The brand offers no PFAS information but the material itself presents minimal risk.

What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Silicone degradation or leaching at high temperature
While food-grade silicone is stable at normal baking temperatures, extreme or prolonged heat exposure (well above 600 degrees Fahrenheit) could theoretically cause polymer breakdown. No studies document leaching of silicone oligomers into food under normal home baking use; this remains a low-probability risk.
Bacterial or mold growth in crevices
Silicone's porous surface and the cube mold's interior geometry can trap moisture and food particles if not thoroughly dried after washing. Proper air drying and occasional sanitization (hot dishwasher cycle or brief heat treatment) mitigate this risk.
Residual solvents or unreacted monomers
Low-cost silicone molds may retain trace amounts of unreacted vinyl or methyl groups from the polymerization process. Fat Daddio's does not publish material purity or solvent-residue testing; risk is low but unquantified for this brand specifically.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Contamination during manufacturing or storage
Food-grade silicone molds are not known to harbor residual chemicals from manufacturing. No recalls or complaints of mold-related contamination are on record for Fat Daddio's or comparable silicone mold brands.
Lead
Silicone molds do not use ceramic glazes or enamel coatings where lead or cadmium contamination typically occurs. No evidence suggests pigments used in silicone colorization pose a leaching hazard at food-contact temperatures.

What it's made of and why it matters
This product is a silicone baking mold, a synthetic rubber polymer that is chemically inert at normal baking temperatures. Silicone does not leach lead, cadmium, or other heavy metals into food, and it lacks the coatings (like Teflon-type coating nonstick finishes) that pose fume risks at high heat. The 4.4oz cube shape is designed for portion-controlled baking and holds food without reactive interactions across typical home-use temperature ranges (up to around 500-600 degrees Fahrenheit for most silicone molds).
The brand's record and disclosure
Fat Daddio's is a U.S.-based baking supply brand known for silicone molds and specialty cookware. The company has not publicly disclosed material sourcing, third-party certifications (such as FDA or NSF), or chemical testing results for its products. No recalls or safety complaints specific to Fat Daddio's silicone molds appear in public records. The brand's silence on PFAS and broader material transparency reflects a common industry practice for cookware brands in this segment.
How it compares in its category
Silicone baking molds are among the lowest-risk cookware options compared to ceramic-coated metal pans (glaze contamination risk), nonstick aluminum cookware (Teflon-type coating shedding risk), or glazed ceramics (lead leaching risk). Within the silicone mold category, Fat Daddio's is a mid-market brand with similar profile to store-brand silicone molds; there is no established performance difference in safety between major silicone mold manufacturers.
If you buy it
Use this mold within the temperature range stated on the product label, typically not exceeding 500-600 degrees Fahrenheit. Hand wash or place on the top rack of the dishwasher; avoid prolonged contact with sharp utensils that could scratch or puncture the silicone. Replace the mold if it develops tears, permanent discoloration, or sticky residue that does not wash away, as these may indicate degradation. Avoid exposing it to direct flame or extended heat storage.
