Preheat the oven to 350 degrees F. Line a standard cupcake pan with 12 standard cupcake liners.
Sift the flour, baking soda and salt into a medium bowl. Set the bowl aside.
In the bowl of an electric stand mixer, cream the brown sugar and margarine with the whisk attachment, about 5 minutes. Scrape down the sides and bottom of the bowl. In a small bowl or cup, combine 1/4 cup plus 2 tablespoons water and the egg replacer and stir to dissolve the egg replacer. Add the egg replacer to the sugar and mix until combined.
In a small bowl, combine the soymilk and vinegar and set aside.
Turn the mixer speed to low and slowly add the dry ingredients and the soymilk, alternating between the two, ending with the soymilk.
Fill the cupcake liners three-quarters full with batter and bake or until a toothpick inserted into each cupcake comes out clean, about 19 minutes. Cool the cupcakes completely.
To assemble: With a plastic drinking straw or a small paring knife, make holes in the center of each cupcake. Squeeze the Coconut Custard Filling in the center of each cupcake until filled but not overflowing, about 1 tablespoon per cupcake. Pipe a dollop of Spiced Rum Frosting onto each cupcake and garnish with a few pieces of the Cracked Brown Sugar Brittle. This recipe was created by a contestant during a cooking competition.

Coconut Custard Filling:
In a medium heavy-bottomed saucepot, stir together 1 3/4 cups of the coconut milk and the sugar. Heat on medium-high until the mixture begins to bubble around the edges.
In a small bowl, mix the remaining 1/4 cup coconut milk and the cornstarch into a slurry. Slowly add the cornstarch mixture to the hot sugar mixture while whisking. Cook for 2 more minutes while stirring. Remove from heat and let cool completely. Put the cooled Coconut Custard into a piping bag and cut 1/4-inch off the tip. Yield: 2 cups.
Spiced Rum Frosting:
In the bowl of a stand mixer, whip the margarine and shortening until completely combined. Scrape the bottom of the bowl to ensure that all ingredients are mixed thoroughly. On low speed, slowly add the powdered sugar a little at a time. Add the cinnamon, allspice and cloves, and mix. Scrape the bottom of the bowl. Add the rum and mix to combine. Scrape the bottom of the bowl and mix on medium-high speed until all the ingredients are combined and the frosting is fluffy, about 2 minutes. Put the frosting into a pastry bag and cut 1/2-inch off the tip. Yield: 2 quarts.
Ingredients and Directions
Cracked Brown Sugar Brittle:
Line a cookie sheet with parchment paper and set aside. In a medium heavy-bottomed saucepan, boil the sugar, corn syrup, 1/4 cup water and salt, stirring until the sugar dissolves. Place a candy thermometer into the pan and cook on medium heat until the mixture reaches 300 degrees F. Remove from the heat and stir in the baking soda and margarine. Pour the mixture onto the prepared cookie sheet and quickly spread the hot mixture thinly on the sheet. Let the candy cool completely and break it into small pieces with your fingers.
