## Abstract

A two piece mold assembly is comprised of flexible material, suitable for baking wherein the two pieces are joined together in a vertical orientation or a stacked orientation and held together by an interlocking seal structure. Once joined together, the mold assembly defines an interior cavity defining a shape for a baked comestible product. A comestible substance is injected into the interior cavity through an aperture in the top of the mold assembly that is either defined by one or more of the two pieces. The interlocking seal prevents egression of injected liquid from extruding outside the mold assembly. After baking, the pieces of the mold can be peeled away from the comestible product at the interlocking seal structure.

## Claims

### Claim 1

An apparatus for casting a baked comestible product, the apparatus comprising:
a mold assembly comprising a first piece and a second piece, wherein the first piece and the second piece each includes an interior side and an exterior side, and wherein the first piece and the second piece are configured to be joined together with the interior sides facing each other;
the interior side of each of the first piece and the second piece comprising:
a mold surface area configured to define a shape for at least a portion of the baked comestible product;
a mold surface area edge;
a seal structure configured to interlock with a seal structure of the other piece to form an interlocking seal; and
the mold assembly defining an interior cavity consisting of the mold surface area of the first piece and the mold surface area of the second piece, wherein the mold surface area edge of the first piece aligns with the mold surface area edge of the second piece and wherein the interior cavity defines a shape for the baked comestible product; and
the mold assembly having a top and a bottom, and wherein the mold assembly defines one or more apertures configured to: allow a comestible substance to be injected into the interior cavity prior to a baking process and vent heat during the baking process, and wherein the one or more apertures are proximate to the top of the mold assembly;
wherein the interlocking seal is configured to secure the interior side of the first piece to the interior side of the second piece to inhibit egression of the comestible substance beyond the aligned mold surface area edge of the first piece and the mold surface area edge of the second piece;
wherein the mold assembly consists of flexible material suitable for baking; and
wherein one or more of the first piece and the second piece can be peeled away from the comestible product after baking at the interlocking seal.

### Claim 2 (depends on 1)
