Preheat your oven to 350°F (175°C) and line a cupcake tin with paper liners.
Sift together the flour, cocoa powder, baking soda, salt, and sugar into a large mixing bowl. This ensures the dry ingredients are evenly combined and lightened.
In a separate bowl, whisk together the plant-based milk, vegetable oil, strawberry puree, vinegar, and vanilla extract until smooth and slightly frothy. This mixture introduces the wet ingredients and the strawberry flavor.
Pour the wet mixture into the dry ingredients and gently fold with a spatula or whisk until just combined. Avoid overmixing to keep the cupcakes tender.
Divide the batter evenly among the cupcake liners, filling each about two-thirds full. Tap the tin gently on the counter to release any air bubbles.
Bake in the preheated oven for 18-20 minutes, or until a toothpick inserted into the center comes out clean. The cupcakes will be slightly risen and fragrant with cocoa and strawberry aroma.
Remove the cupcakes from the oven and let them cool in the tin for a few minutes. Then transfer them to a wire rack and allow to cool completely before frosting.
Garnish with sliced strawberries or whole berries on top before serving for a fresh, fruity touch. The vibrant red color and delicate crumb make these cupcakes a beautiful treat.
