Preheat oven to 350°F (175°C). Grease each ramekin thoroughly with 1½ teaspoons of butter-flavored shortening. Coat the inside with turbinado sugar, rotating the ramekin to ensure even coverage. Tap out the excess.
In a mixing bowl, cream together ½ cup butter-flavored shortening and 1 cup granulated sugar until light and fluffy. Add the eggs, one at a time, beating well after each addition. Mix in the vanilla bean paste (or extract). In a separate bowl, whisk together flour, baking powder, and salt. Alternately add the dry ingredients and milk to the creamed mixture, beginning and ending with the dry ingredients. Mix until just combined do not overmix.
Divide the batter evenly among the prepared ramekins. Place ramekins on a baking sheet and bake for 25–30 minutes, or until the tops are golden and a toothpick inserted comes out clean. Let cakes cool slightly (about 5 minutes), then carefully invert onto serving plates.
In a small saucepan, combine raspberries, sugar, and water. Bring to a gentle simmer over medium heat. Cook for 5–7 minutes, stirring occasionally, until the berries break down and the sauce thickens slightly. Strain through a fine mesh sieve for a smooth sauce (optional).
Top the warm butter cakes with a scoop of vanilla ice cream. Drizzle with the raspberry sauce and garnish with fresh raspberries. Serve immediately for the ultimate warm, rich dessert experience.
