Follow these simple steps to create your Chocolate Strawberry Cupcakes:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and line a muffin tin with cupcake liners.
2. Mix Dry Ingredients: In a large bowl, combine the flour, cocoa powder, sugar, baking powder, baking soda, and salt.
3. Combine Wet Ingredients: In a separate bowl, whisk together the milk, vegetable oil, eggs, and vanilla extract until well combined.
4. Combine Mixtures: Gradually add the wet ingredients to the dry ingredients, mixing until just combined.
5. Add Boiling Water: Carefully stir in the boiling water until the batter is smooth. The batter will be thin, which is normal.
6. Fill the Cupcake Liners: Pour the batter into the prepared muffin tin, filling each liner about two-thirds full.
7. Bake: Place in the preheated oven and bake for 20-25 minutes or until a toothpick inserted in the center comes out clean.
8. Cool the Cupcakes: Remove from the oven and let the cupcakes cool in the tin for 10 minutes before transferring them to a wire rack to cool completely.
9. Prepare the Frosting: While the cupcakes are cooling, blend the butter until creamy. Gradually add the powdered sugar and mix well.
10. Add Strawberry Puree: Blend the fresh strawberries into a puree and mix it into the frosting until fully incorporated. Adjust the sweetness with more powdered sugar if needed.
11. Frost the Cupcakes: Once the cupcakes are completely cooled, frost them generously with the strawberry frosting.
12. Decorate: Top each cupcake with a fresh strawberry for an elegant touch.
