These cupcakes combine a simple boxed yellow cake mix with a homemade tres leches soak, resulting in ultra-moist, flavorful treats that soak overnight for the perfect texture. Ideal for last-minute parties or fuss-free desserts that impress.

Ingredients

Scale
  • 1 (15.25 oz) box yellow cake mix (recommend Duncan Hines)
  • 3 large eggs, room temperature
  • 1/3 cup (80 ml) vegetable oil
  • 1 cup (240 ml) water
  • 1 (14 oz / 396 g) can sweetened condensed milk
  • 1 (12 oz / 354 ml) can evaporated milk
  • 1/2 cup (120 ml) whole milk
  • 1 teaspoon pure vanilla extract
  • Whipped cream (for topping, homemade or store-bought)
  • Cinnamon (optional, for garnish)

Instructions

  1. Preheat your oven to 350°F (175°C). Prepare your muffin tin by lining with cupcake liners or greasing well.
  2. In a large bowl, combine the boxed cake mix, 3 large eggs, 1/3 cup vegetable oil, and 1 cup water. Beat with an electric mixer on medium speed for 2 minutes or whisk vigorously by hand until smooth.
  3. Fill the cupcake liners about 2/3 full with batter.
  4. Bake for 18-22 minutes. Use a toothpick inserted in the center of a cupcake to test doneness; it should come out clean.
  5. Cool cupcakes completely on a cooling rack for at least 30 minutes before soaking.
  6. In a medium bowl, whisk together sweetened condensed milk, evaporated milk, whole milk, and vanilla extract until combined.
  7. Using a fork or skewer, poke holes all over each cupcake to help the soak penetrate.
  8. Place cupcakes in a deep baking dish or tray and pour the milk mixture evenly over them. Cover tightly with plastic wrap.
  9. Chill overnight (at least 6 hours) to allow cupcakes to absorb the tres leches mixture fully.
  10. Serve topped with whipped cream and a sprinkle of cinnamon. Optionally add fresh fruit or toasted coconut flakes.

Notes

Use room temperature eggs and milk for better batter consistency. Poke holes gently to avoid cupcakes falling apart. Soaking overnight (at least 6 hours) yields best texture, but 4 hours minimum works. Cover cupcakes while soaking to prevent drying out. For dairy-free version, substitute evaporated and whole milk with coconut milk and use dairy-free whipped topping. Fresh berries or toasted coconut flakes make great toppings.
