b. a fastener affixed through each fastener aperture; c. a latch affixed rotatably to each outer corner edge of each of the plurality of the heat vents by the fastener; d. a cover affixed rotatably to each outer corner edge of each of the plurality of the heat vents with each latch by the fastener, said cover and latch rotating independently of each other wherein said cover able to cover a heating vent; and e. an inner heating channel having a wall vent for each of said heating vents, said wall vents having a base and ascending inner and outer walls arranged similarly to said heating vents and able to extend through said heating vents, said base being larger than said heating vents and having rectangular cutouts along its outer edge at locations near said latches wherein said latches can secure said base to said pie pan. ### Claim 2 (depends on 1) The pie pan baking device of claim 1, wherein said plurality of heating vents are three heating vents. ### Claim 3 (depends on 1) The pie pan baking device of claim 1, wherein the wall vent is about ⅛ inch to about ½ inch taller than the pie pan. ### Claim 4 A baking device for a pie pan comprising: a circular heating channel having a base, ascending inner and outer walls and a top edge along said ascending inner and outer walls, wherein the distance between said ascending inner and outer walls is from about ⅛ to about ½ inch and wherein the ascending outer wall diameter of said baking device is from about 3 inches to about 7 inches, wherein the ascending outer wall further comprises a means for removing said baking device from said pie pan and wherein said means for removing is one or more apertures along said top edge of said ascending outer wall, a lip formed from or added to the said top edge of said ascending outer wall, and/or one or more tabs formed from or added to the said top edge of said ascending outer wall. ### Claim 5 A baking device for a pie pan comprising: a circular heating channel having a base, ascending inner and outer walls and a top edge along said ascending inner and outer walls, wherein the distance between said ascending inner and outer walls is from about ⅛ to about ½ inch and wherein the ascending outer wall diameter of said baking device is from about 3 inches to about 7 inches, further comprising a removable lid that rests on top of said ascending outer wall and/or ascending inner wall and covering the wall vent or when said ascending outer wall is taller than said ascending inner wall, said removable lid rests on top of said ascending inner wall and fits flush against said ascending outer wall. ### Claim 6 A pie pan baking device comprising: a pie pan; and a circular heating channel having a base, ascending inner and outer walls and a top edge along said ascending inner and outer walls, wherein the distance between said ascending inner and outer walls is from about ⅛ to about ½ inch and wherein the ascending outer diameter of said baking device is from about 3 inches to about 7 inches, wherein said ascending outer wall comprises a means for removing said baking device from said pie pan; and wherein said means for removing is one or more apertures along said top edge of said ascending outer wall, a lip formed from or added to said top edge of said ascending outer wall, and/or one or more tabs formed from or added to said top edge of said ascending outer wall. ### Claim 7 (depends on 6) The pie pan baking device according to claim 6, wherein said ascending inner wall further comprises a plurality of apertures. ### Claim 8 (depends on 7) The pie pan baking device according to claim 7, wherein said plurality of apertures have a diameter of about 1/16 to about 3/16 in diameter. ### Claim 9 (depends on 6) The pie pan baking device according to claim 6, wherein said pie pan further comprises a circular indentation in its base able to receive said circular heating channel. ### Claim 10 (depends on 6) The pie pan baking device of claim 6, wherein the circular heating channel is about ⅛ inch to about ½ inch taller than the pie pan. ### Claim 11 (depends on 6) The pie pan baking device according to claim 6, wherein the ascending outer wall is about ⅛ to about ¾ inches taller than said ascending inner wall. ### Claim 12 A pie pan baking device comprising: a pie pan; a circular heating channel having a base, ascending inner and outer walls and a top edge along said ascending inner and outer walls, wherein the distance between said ascending inner and outer walls is from about ⅛ to about ½ inch and wherein the ascending outer diameter of said baking device is from about 3 inches to about 7 inches; and a removable lid that rests on top of said ascending outer wall and/or ascending inner wall and covering the wall vent or when said ascending outer wall is taller than said ascending inner wall, said removable lid rests on top of said ascending inner wall and fits flush against said ascending outer wall. ### Claim 13 (depends on 12) The pie pan baking device according to claim 12, wherein said pie pan further comprises a circular indentation in its base able to receive said circular heating channel. ### Claim 14 (depends on 12) The pie pan baking device of claim 12, wherein the circular heating channel is about ⅛ inch to about ½ inch taller than the pie pan. ### Claim 15 (depends on 12) The pie pan baking device according to claim 12, wherein the ascending outer wall is about ⅛ to about ¾ inches taller than said ascending inner wall.
