Blend the silken tofu. I use an immersion blender.
Place the silicone brand molds on a baking sheet or something flat and sturdy.
Add soy milk, sugar, strawberry, and agar agar to a pot.
Whisk together really well.
Cook on medium-low heat for 4-5 minutes, stirring continuously. Set a timer to make sure you cook it for long enough; this is really important to ensure that the agar agar will set. You should reach a very low boil.
Once you've cooked the strawberry milk mixture, add the blender silken tofu, and whisk it together well.
The next few steps need to be done quickly, because the mixture does start setting pretty fast.
Fill each of the brain molds up about halfway with the silken tofu mixture. Also push some of the tofu mixture up the sides of each brain mold.
Add about 2 tsp of cherry pie filling to each of the brain molds. This should be in the middle of the molds and shouldn't touch the sides.
Top off each brain mold with the remaining silken tofu mixture.
Allow these to get to about room temperature on the counter before putting in the fridge.
Throw in the fridge for about 20 minutes or until the brains have set!
