Wilton Silicone Baking Cups
Lower concern. Silicone cups unlikely to contain PFAS.
Wilton silicone baking cups are made from food-grade silicone, an inherently PFAS-free elastomer. Brand makes no PFAS claims but material type itself poses lower risk than nonstick coatings.

The full breakdown
What it's made of and why it matters
Wilton Silicone Baking Cups are made from food-grade silicone, a synthetic rubber polymer that does not contain the reactive chemical groups found in plastics like BPA or phthalates. Silicone has a high heat tolerance (typically safe to 450-500F) and is chemically inert at normal baking temperatures, meaning it does not leach or degrade readily. The material is non-porous and does not absorb oils or odors, reducing the risk of contamination accumulation over time.
The brand's record and disclosure
Wilton is a long-established US-based baking brand owned by Estes Lauder Companies. The company does not publish detailed chemical composition or third-party testing statements specific to these cups. No product recalls or safety warnings related to Wilton Silicone Baking Cups appear in public FDA or CPSC records. The brand markets these cups as food-grade but provides minimal transparency on manufacturing standards or testing protocols.
How it compares in its category
Silicone baking cups are safer than paper liners (no bleach or adhesive concerns) and more durable than single-use alternatives. They avoid the coating-degradation and metal-leaching risks of some non-stick ceramic or metal muffin tins. Compared to reusable silicone from boutique brands, Wilton offers similar material safety at a lower price point, though without the enhanced disclosure or certification some competitors provide.
If you buy it
Wilicone cups are dishwasher safe but hand washing extends lifespan. Do not exceed manufacturer heat guidelines (typically 450F); overheating silicone can cause material degradation and potential odor release. Store in a cool, dry place away from strong sunlight, as UV exposure degrades silicone over years. Replace cups if visible tears, discoloration, or persistent odor develop; these signal material breakdown.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Silicone leaching under extreme heat or degradation
While food-grade silicone is chemically stable at normal baking temperatures, sustained exposure above 500F or repeated thermal cycling can cause microscopic material degradation. No documented cases of harm from Wilton cups at intended temperatures, but risk exists if misused in ovens hotter than specified.
Odor absorption and off-gassing
Silicone can absorb strong food odors and volatile compounds from adjacent oven contents; some users report persistent smell after heating. This is cosmetic nuisance rather than safety risk but indicates material interaction with heated substances.
Manufacturing impurities or unreacted monomers
Food-grade silicone certification suggests compliance with FDA standards for unreacted oligomers and heavy metals, but Wilton does not publish residual monomer testing. No recalls or complaints on record for this product.
Bacterial growth if not dried properly
Silicone's porosity is low, but crevices and seams can retain moisture. Improper drying between uses may foster mold or bacterial colonies; standard dishwasher or hand-washing with thorough drying prevents this.
Lead or cadmium in pigments or fillers
No evidence of heavy metal contamination in Wilton silicone cups. Food-grade silicone certification implies testing for lead and cadmium, though Wilton does not disclose detailed analytical results.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
