Special equipment: 2 piping bags
For the cream puffs: Preheat the oven to 400 degrees F. Line a baking sheet with parchment paper.
Whisk the flour and salt in a small bowl.
Put the butter and water in a medium saucepan over medium heat. When the water begins to boil and the butter is melted, add the flour mixture all at once and stir constantly with a wooden spoon until the mixture forms a ball and pulls away from the sides of the pot, about 3 minutes. Remove the saucepan from the heat and cool the dough until it is no longer steaming, at least 5 minutes.
Using a wooden spoon, beat the eggs into the dough, one at a time. Once all the eggs are incorporated, put the dough in a piping bag. Cut the tip of the piping bag about 1/2-inch from the point. Pipe 16 equal-size mounds of dough onto the prepared baking sheet, leaving about 1 inch between each mound.
Bake for 10 minutes. Lower the heat to 350 degrees F and bake for another 30 minutes. Cool on a wire rack. Cut the cooled cream puffs in half horizontally.
For the Chantilly cream: Put the cream in the bowl of a stand mixer fitted with the whisk attachment. Begin whisking on medium speed. Slowly add the 1/4 cup confectioners' sugar, then whisk until stiff peaks form. Turn the mixer to low speed and slowly add the RumChata until combined.
To assemble: Put the Chantilly cream in a pastry bag and cut the tip about 1 inch from the point. Pipe some Chantilly cream into bottom halves of the cream puffs and top with the top halves. Dust with confectioners' sugar and serve.
