Creating Chocolate Raspberry Cupcakes is a straightforward process when you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with cupcake liners.
2. Mix Dry Ingredients: In a large bowl, combine the flour, sugar, cocoa powder, baking powder, baking soda, and salt. Whisk until well combined.
3. Cream Butter: In another bowl, beat the softened butter until creamy. Add the eggs and vanilla extract, mixing until smooth.
4. Combine Mixtures: Gradually add the dry ingredients to the butter mixture, alternating with the milk. Mix until just combined.
5. Add Boiling Water: Carefully stir in the boiling water until the batter is smooth. The batter will be thin.
6. Fill Cupcake Liners: Pour the batter evenly into the prepared muffin tin, filling each liner about two-thirds full.
7. Bake: Place the tin in the preheated oven and bake for 20-25 minutes or until a toothpick inserted in the center comes out clean.
8. Cool: Remove from the oven and let the cupcakes cool in the tin for about 15 minutes. Then, transfer them to wire racks to cool completely.
9. Prepare Raspberry Filling: While the cupcakes cool, mash the fresh raspberries in a small bowl. You can add a teaspoon of sugar if you prefer a sweeter filling.
10. Fill Cupcakes: Once the cupcakes are completely cool, use a small knife or cupcake corer to create a small hole in the center of each cupcake. Fill each hole with the mashed raspberries.
11. Frost the Cupcakes: Top each filled cupcake with chocolate frosting, spreading it generously over the top.
12. Garnish: Add a few whole raspberries on top of the frosting for a beautiful presentation.

These steps will guide you in creating these incredible cupcakes effortlessly.
