Melt the milk chocolate chips in a microwave or with a double boiler. If microwaving, zap the chocolate chips in a microwave-safe bowl with 15-second increments until melted.
On a sheet of cellophane or wax paper, pour a small portion of chocolate to make chocolate disks (the polar bear’s eyes and ears). Similarly, pour some chocolate onto the sheet to make the bear’s nose. Adjust shaping the chocolate by poking it with a tookpick. Make sure the chocolate is thick enough so it doesn’t break when removed from the sheet. Let it dry until hardened.
Melt the white chocolate chips in a microwave or with a double boiler. If microwaving, zap the chocolate chips in a microwave-safe bowl with 15-second increments until melted. Add a dash of teal gel food coloring and mix until well combined.
Create a small disk on top of the chocolate disks for the polar bear’s ears. Let them dry until hardened.
Once the chocolate pieces are hardened, remove the plastic wrap and invert a large plate on top of the bowl. In one quick motion, flip the cake upside-down. Remove the bowl and the plastic wrap that is covering the cake. *Make sure to use the plate you are happy with to decorate. This cake is very hard to transfer after being flipped on a plate!
With ¼ of the cream cheese filling, cover the entire cake. Don’t worry if any blueberry jam seeps through – all will be covered by another layer of the filling.
Put the rest of the cream cheese filling into a piping bag with a star tip. Start piping a small portion of the cream cheese filling until the entire cake is covered. Make sure to pipe extra filling where the polar bear’s ears will be at.
Place the chocolate pieces on top of the frosting to create the face.
(Optional) With a cooking tweezer, press down the pointy tips of the white chocolate chips to flatten then stick the white chocolate chips to the milk chocolate eyes to add some twinkles.
