In a small saucepan over medium heat, combine frozen raspberries, sugar, and lemon juice. Mash the berries and simmer for 5 to 7 minutes, stirring frequently. Dissolve cornstarch in a small amount of water and stir into the mixture. Simmer until thickened, about 1 to 2 minutes. Strain through a fine mesh sieve for a smooth texture, then cool completely before use.

Preheat oven to 175°C (350°F). Line a 12-cup muffin pan with paper liners. In a large bowl, whisk together flour, sugar, cocoa powder, baking powder, baking soda, and salt. Add milk, vegetable oil, egg, and vanilla extract; mix until well combined. Gradually whisk in hot water until batter is smooth and thin.

Divide batter evenly among liners, filling each about two-thirds full. Bake for 18 to 20 minutes or until a toothpick inserted into the center comes out with a few moist crumbs. Cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.

Once cooled, remove a small cone from the center of each cupcake using a knife or corer. Spoon 5 to 7 ml of raspberry filling into each cavity. Replace the cake plug if desired.

Drizzle remaining raspberry glaze over cupcake tops, allowing it to drip naturally for a dramatic effect. Top each cupcake with a fresh raspberry. Serve promptly.
