Ingredients:
- 1 ½ cups (192g) all-purpose flour, spooned and leveled
- ¾ cup (75g) unsweetened cocoa powder
- 1 ½ teaspoons baking powder
- ¾ teaspoon baking soda
- ¾ teaspoon salt
- 1 ½ cups (300g) granulated sugar
- ¾ cup (180ml) vegetable oil
- 1 ½ teaspoons vanilla extract
- 1 ½ cups (360ml) hot coffee or hot water
- 1 large egg
- 1 cup (2 sticks/226g) unsalted butter, softened
- 3 cups (360g) powdered sugar, sifted
- 3 tablespoons milk
- 1 teaspoon vanilla extract
- Pinch of salt
- 1 pound (450g) fresh strawberries, hulled and halved
- ¼ cup (50g) granulated sugar
- 2 tablespoons lemon juice, freshly squeezed
- 1 tablespoon water
- Optional: Red food coloring, gel or liquid
Instructions:
- Combine strawberries, sugar, lemon juice, and water in a saucepan. Simmer over medium heat, stirring occasionally, until the strawberries have softened and released their juices (about 10-15 minutes).
- Carefully transfer the strawberry mixture to a blender or food processor. Blend until smooth. Strain the coulis through a fine-mesh sieve to remove seeds (optional, but recommended for a smoother texture). Taste and adjust sweetness as needed. Stir in a tiny drop of red food coloring if desired. Let cool completely.
- Preheat oven to 350°F (175°C). Line a 12-cup muffin tin with cupcake liners.
- Whisk together dry ingredients (flour, cocoa, baking powder, baking soda, salt) in a large bowl.
- In a separate bowl, combine sugar, oil, vanilla, hot coffee/water, and egg. Whisk until smooth.
- Gradually add the wet ingredients to the dry ingredients, mixing on low speed until just combined. Do not overmix.
- Fill each cupcake liner about 2/3 full.
- Bake for 20-22 minutes, or until a toothpick inserted into the center comes out clean.
- Let the cupcakes cool in the muffin tin for a few minutes before transferring them to a wire rack to cool completely.
- Cream the softened butter until light and fluffy. Gradually add the sifted powdered sugar, alternating with the milk, until smooth and creamy. Stir in the vanilla extract and salt.
- Once the cupcakes are completely cool, frost them with the vanilla buttercream. Use a piping bag or simply spread with a knife.
- Using a small knife or melon baller, carefully cut a small, circular 'bite' out of the top of each cupcake.
- Spoon the cooled strawberry coulis into the 'bite' in each cupcake, letting it ooze slightly.
- Serve immediately or chill for later.
