Easy Rainbow Chip Tres Leches Cake

Recipe Ingredients

This cake is so easy to make with just a few simple ingredients.

Cake Ingredients

Party Rainbow Chip Cake Mix: This is the primary base for the cake. It contains all the dry ingredients necessary for an easy-to-prepare cake batter.  

Evaporated Milk: It provides a rich, creamy, and slightly savory milk base for the soak.

Sweetened Condensed Milk: Is essential for providing the sweetness and a significant portion of the rich, dense, and syrupy texture to the tres leches soak, balancing the evaporated milk.

Heavy Whipping Cream (or Whole Milk): Adds extra richness, making the cake even more decadent and moist. Alternatively, for those who prefer a less intensely rich soak, whole milk provides a slightly lighter texture and less richness than heavy cream, while still contributing to the overall milk volume and moisture.

Vanilla: It adds a warm, aromatic, and sweet note to the milk mixture, complementing the dairy flavors and adding depth to the overall taste of the cake.

Other Ingredients You’ll Need: Water, vegetable oil, and eggs.

Topping Ingredients

Heavy Whipping Cream: This forms the classic, fluffy topping for tres leches cake.

Powdered Sugar: Sweetens the whipped cream.  

Vanilla: Like the vanilla in the milk mixture, this adds a pleasant, aromatic flavor to the whipped cream, enhancing its sweetness and overall appeal.

Rainbow Sprinkles (if desired): They add a festive, colorful touch to the finished cake.

How to Make Easy Rainbow Chip Tres Leches Cake

Get ready to bake a rainbow of delish! Here's how to whip up your own Easy Rainbow Chip Tres Leches Cake in just a few steps. See the full recipe below for all the details.

1. Bake Your Base 

Grab your rainbow chip cake mix and combine it with water, oil, and eggs. Beat it until smooth, pour it into your pan, and bake.

2. Whip Up the Milk Bath

While your cake is cooling, it's time to create the tres leches soak. In a bowl, whisk together the evaporated milk, sweetened condensed milk, heavy whipping cream (or whole milk), and a splash of vanilla. This is the secret sauce that transforms your cake into an unbelievably moist dream!

3. Give Your Cake a Milk Bath

Once your cake is slightly cooled but still warm, grab a fork or the handle of a wooden spoon and poke holes all over the top. Don't be shy – you want those holes to go almost all the way to the bottom. Slowly and evenly pour your milky mixture over the entire cake, letting it soak in. You might need to pour it in stages, giving the cake time to drink it all up.

4. Chill

Cover your pan tightly with plastic wrap and place in the refrigerator. Let it chill for at least 4 hours, or even better, overnight.

5. Top It Off

Just before you're ready to serve, use a chilled bowl and beat your cold heavy whipping cream, powdered sugar, and a hint of vanilla until stiff peaks form. Spread evenly over your chilled cake, and for the ultimate rainbow celebration, shower it with rainbow sprinkles!
