Copycat Crumbl Cookies & Cream Tres Leches Cake

ByZoe

Soft, soaked, chilled, chocolatey, creamy, and EXACTLY like the Crumbl cake slice — not the cookie.

This cake is a melt-in-your-mouth square of chocolate sponge soaked in a lightly chocolate-kissed tres leches mixture, topped with a silky Oreo-cream frosting. The real beauty of this dessert is how the cake keeps its structure even after soaking, giving you that airy, cloud-soft bite Crumbl is known for.

INGREDIENTS

Chocolate Sponge Cake

1 cup all-purpose flour

½ cup cocoa powder

1 ½ tsp baking powder

¼ tsp salt

5 large eggs, separated

1 cup sugar (½ cup for yolks, ½ cup for whites)

⅓ cup whole milk

1 tsp vanilla extract

Chocolate Tres Leches Soak

½ cup sweetened condensed milk

½ cup evaporated milk

½ cup whole milk

1 tbsp cocoa powder

1 tsp sugar

Cookies & Cream Topping

6 oz cold cream cheese

1 cup cold heavy cream

½ cup powdered sugar

1 tsp vanilla

6 Oreo cookies, finely crushed into powder

INSTRUCTIONS

1. Bake the Chocolate Sponge

Preheat oven to 350°F. Line a 9×13 pan with parchment. In bowl 1: whisk flour, cocoa, baking powder, salt. In bowl 2: beat egg yolks + ½ cup sugar until pale and thick (about 2–3 mins). Add milk + vanilla to yolk mixture. In bowl 3: whip egg whites to soft peaks, then slowly add remaining ½ cup sugar to make glossy stiff peaks. Fold yolk mixture into whites VERY gently. Fold in dry ingredients, keeping batter airy. Pour into pan and bake 22–26 minutes until the center springs back when tapped. Let cool 15 minutes. Poke 25–30 holes with a fork (not too deep).

2. Make the Chocolate Tres Leches Mixture

Whisk all ingredients together. Microwave 10 seconds to dissolve cocoa. Let cool completely — you don’t want warm milk soaking the cake.

3. Soak the Cake

Pour the tres leches mixture slowly and evenly over the entire cake. The cake will look like it’s drowning — that’s correct. Chill at least 4 hours, ideally overnight.

4. Make the Cookies & Cream Frosting

Beat cold cream cheese until smooth. Add powdered sugar + vanilla. Separately whip heavy cream to stiff peaks. Fold whipped cream + crushed Oreos into the cream cheese mixture. Chill 15 minutes for the Crumbl-style thickness.

5. Assemble

Spread the topping thickly over the fully chilled cake. Add extra Oreo dust or crumble if desired. Slice into 9 large Crumbl-sized squares.

TIPS (These are what make it Crumbl-accurate)

✨ Use a sponge cake, not a regular chocolate cake. Density ruins the soak.

✨ Let it chill overnight if you want the fully saturated bite Crumbl is known for.

✨ Use Oreo powder, not chunks, or the frosting won’t be silky enough.

✨ Serve cold, not room temperature — this dessert is meant to be chilled.
