This dulce de leche caramel waffle cake is one of the simplest and most satisfying no-bake desserts you can make. A creamy mixture of whipped butter and rich dulce de leche is spread between plain wafer sheets, creating thin, caramel-scented layers that soften and meld as the cake rests. It’s an Eastern European classic that’s been a family favorite for years—delicious, nostalgic, and incredibly easy to assemble.
The texture is what sets this cake apart: layers remain light and slightly crisp while the filling becomes soft and melt-in-your-mouth. It never gets soggy if you give the assembled cake time to settle under weight, and the balance of buttery caramel filling with delicate wafers makes each bite irresistible.

Why you’ll LOVE this recipe
- Simple, three-ingredient dessert: just butter, dulce de leche, and plain wafer sheets for a decadent result.

📝 Key ingredients
Read through for tips to ensure success.
Full steps and ingredients are in the recipe card below.
- Butter: Unsalted, softened butter whipped until light and creamy. You’ll need 1 cup.
- Wafer sheets: Plain wafer or waffle sheets work best. The recipe uses eight large 10″ square sheets, but round or smaller sheets can be substituted—just adjust the number used.
- Dulce de leche: Use real dulce de leche (cooked sweetened condensed milk). It should be thick, dark brown, and caramelized. Avoid products labeled merely as sweetened condensed milk with flavoring, which are often too runny.

👩🍳 How to make dulce de leche wafer cake
Step-by-step assembly

Step 1: Place softened butter in a large bowl and beat with an electric mixer until light and creamy.

Step 2: Add sea salt and the dulce de leche, then mix until fully combined and smooth.

Step 3: Spread the filling evenly across each wafer sheet, stacking them as you go. Finish with a plain wafer or sprinkle crushed cookies on top for texture.

Step 4: Cover with parchment and place a cutting board over the cake. Add a weight (a jar or canned goods) and let it rest for about 2 hours to soften and bind the layers.
Hot tip: Resting under weight for 2 hours makes the cake easier to slice and ensures the layers stick together cleanly.

Step 5: Use a serrated knife and a gentle sawing motion to slice the cake into diamonds or squares. Serve and enjoy.
🥄 Make ahead and storage
This cake is ideal for making ahead—its flavor and texture improve as it rests. Store the finished cake tightly covered in the refrigerator for up to one week. For longer storage, freeze portions in an airtight container or freezer bag for up to three months; thaw in the refrigerator before serving.
