Oreo Milk Soak Cake
There are some desserts that instantly take you back to childhood, and Oreos are absolutely one of those flavors for me. This recipe is the second dessert in my Nostalgic Cookie Series, where I’m taking the cookies we all grew up loving and turning them into extra gooey, over-the-top desserts that feel cozy, nostalgic, and just a little ridiculous in the best way.
This Oreo Milk Soak Cake starts with an ultra-soft chocolate cake that’s intentionally baked just barely set so it stays incredibly tender. While it’s still warm, it gets soaked with blended Oreo cream milk made with Double Stuf Oreos, heavy cream, and milk until every bite is rich, creamy, and packed with cookies-and-cream flavor.
Then the entire thing gets topped with the fluffiest Oreo mousse and finished with crushed Oreos all over the top.
The result is somewhere between a poke cake, a mousse cake, and the most nostalgic homemade Oreo dessert ever.

Ingredient Highlights
Double Stuf Oreos
Using Double Stuf Oreos gives the soak and mousse a much stronger cookies-and-cream flavor. The extra creme filling also helps create that super soft texture throughout the dessert.
Hot Coffee
Don’t skip the hot coffee in the cake batter. It deepens the chocolate flavor without making the cake taste like coffee.
Cream Cheese
There’s only a small amount of cream cheese in the mousse, which keeps it light and fluffy while still giving it enough structure to hold beautifully on top of the soaked cake.
How to Make Oreo Milk Soak Cake
1. Make the Chocolate Cake
Whisk together the dry ingredients, then add the egg, buttermilk, oil, and vanilla. Slowly whisk in the hot coffee until smooth.
The batter will be thin — that’s exactly what you want.
Bake the cake until the center is just barely set and still slightly jiggly. This is what gives the cake its ultra-soft texture after soaking.
2. Make the Oreo Milk Soak
Blend together the milk, heavy cream, Double Stuf Oreos, vanilla, and salt until smooth.
The mixture will most likely separate slightly because of the Oreo creme filling. That’s completely normal.
Poke holes all over the warm cake and slowly pour the soak over the top in stages so the cake has time to absorb it.
You want the cake deeply saturated, but not swimming in liquid.
3. Make the Oreo Mousse
Whip the heavy cream to soft-medium peaks first and set aside.
Then make the mousse base with cream cheese, powdered sugar, vanilla, and gelatin before gently folding in the whipped cream and crushed Oreos.
The mousse should feel fluffy, airy, and light.
4. Assemble the Cake
Spread the Oreo mousse over the soaked cake in thick swoops, then finish the entire top with crushed Double Stuf Oreos.
You can serve it right away, but it’s honestly incredible after chilling in the fridge for a few hours or overnight.
Tips for the Best Oreo Milk Soak Cake
- Do not overbake the cake. You want it very soft.
- Don’t use all the soak at once — pour slowly and let the cake absorb it.
- The Oreo soak separating is completely normal.
- Slightly crushing the Oreos into both dust and chunks gives the best texture on top.
- This cake gets even better after chilling overnight.
This Oreo Milk Soak Cake is messy, rich, nostalgic, and exactly the kind of dessert I want to eat straight from the pan with a spoon.

Oreo Milk Soak Cake
Ingredients
Equipment
Method
- Preheat oven to 350°F. Line an 8×8-inch metal pan with parchment paper.
- In a large bowl, whisk together the 90 g (¾ cup) flour, 30 g (¼ cup) cocoa powder, 150 g (¾ cup) sugar, ½ tsp baking soda, scant ½ tsp baking powder, and scant ½ tsp salt.
- Add the 1 egg, 120 g (½ cup) buttermilk, 60 g (¼ cup) oil, and 1 tsp vanilla. Whisk until combined.
- Slowly stream in the 80 g (⅓ cup) hot coffee while whisking until smooth. The batter will be thin.
- Bake for 22–24 minutes, until the center is just set but still barely soft. The pan should still have a slight jiggle when moved.
- Do not use the toothpick test for this cake — you want it very soft.
- Let cool for just 10–15 minutes maximum before soaking.
- Blend together the 120 g (½ cup) whole milk, 90 g (6 tbsp) heavy cream, 6 Double Stuf Oreos, pinch of salt, and ½ tsp vanilla until smooth.
- The mixture will most likely split because of the extra creme filling in the Double Stuf Oreos. That’s completely okay — it just doesn’t look very pretty.
- Do not warm the soak before pouring.
- Using the handle of a wooden spoon or a thick skewer, poke holes all throughout the warm cake.
- Slowly pour some of the Oreo soak over the cake, then let it sit for about 5 minutes to absorb.
- Check to see if some spots soaked more than others before continuing.
- You may not use all of the Oreo milk soak. You want the cake deeply saturated, but not flooded into a puddle.
- Once the soak is absorbed, move on to the mousse. This is a great time to make it.
- Before starting the mousse, whip the 230 g (1 cup) heavy cream first so you don’t have to wash the beaters later.
- Whip the cream to soft-medium peaks, then place in the refrigerator while preparing the rest of the mousse.
- Sprinkle the 1 tsp gelatin over the 1½ tbsp cold water. Let bloom for 5 minutes.
- Microwave for 5–8 seconds until melted and liquid.
- In a bowl, beat together the 60 g (¼ cup) softened cream cheese, 75 g (⅔ cup) powdered sugar, and 1 tsp vanilla until smooth.
- Slowly stream in the gelatin while mixing.
- Fold in the whipped cream gently until airy and combined.
- Fold in the finely crushed Oreos last.
- Spread the Oreo mousse over the soaked cake in thick swoops.
- Top the entire cake with more crushed Double Stuf Oreos.
- You can dig in immediately, or chill before serving.
- It’s especially good the next day cold.
Notes
- Slightly underbaking the cake is intentional and gives it the ultra-soft texture.
- Double Stuf Oreos create the best flavor for this recipe.
- The Oreo soak separating is completely normal.
- Store covered in the refrigerator for up to 3 days.
