Method
- Step 1: In a medium pot, combine 300 ml of milk (reserving a small splash), sugar, and vanilla sugar. Heat slowly, stirring, until it comes to a boil.
- Step 2: While the milk heats, mix the cornstarch with the reserved small amount of cold milk in a small cup or bowl until lump-free, creating a thin paste.
- Step 3: Once the milk in the pot boils, briefly remove it from the heat. Vigorously whisk the cornstarch mixture into the hot milk. Return the pot to the stove (low to medium heat) and let it boil briefly while stirring constantly until it thickens to a pudding-like consistency. This happens quickly!
- Step 4: Remove the thickened cream from the heat and stir in the 200 ml of cream. Stir well until everything is combined and smooth. Let the cream cool for a few minutes. It doesn't need to be cold, but not boiling hot, so the cookies don't immediately soak through.
- Step 5: Find a suitable dish (a casserole dish, a rectangular cake pan, or even individual glasses work well). Lay a layer of cookies on the bottom. Break cookies to fit if necessary.
- Step 6: Spread a generous layer of the milk-cream mixture over the cookies.
- Step 7: Add another layer of cookies, and then another layer of cream. Alternate layers like this until your dish is almost full.
- Step 8: Important: The last layer should always be cream. This gives the cake a nice finish and keeps the top cookie layer moist.
- Step 9: Cover the dish (with plastic wrap or a lid) and place the cake in the refrigerator. It needs at least 2 hours, preferably 3-4 hours or even overnight, to set properly and for the cookies to soften nicely.
- Step 10: Shortly before serving, make it pretty! Sprinkle the chocolate sprinkles over it or whatever else you like.
- Step 11: Now just slice (or spoon from glasses) and enjoy!
Notes
Tips for Success: To avoid lumps, ALWAYS mix cornstarch with COLD milk before adding it to the hot milk, then whisk it in quickly. Be patient when thickening: let the cream briefly boil and visibly thicken. If it's too liquid, the cake won't set. It should be like a pourable pudding. Chill time is King: Give the cake enough time in the fridge. The cookies need to soften and the cream needs to set. This is the most important step for the texture. When slicing, use a knife briefly dipped in hot water for cleaner cuts.
Variations: Try different cookies (chocolate, ladyfingers, oat, speculoos). Add fresh berries or fruit puree. Stir cocoa powder into the starch mixture or add chopped chocolate to the warm cream. Sprinkle nuts or shredded coconut between layers. For adults, dip cookies briefly in cold coffee.
Storage: If there are leftovers, store the cake covered in the refrigerator. It keeps well for 2-3 days. The longer it sits, the softer the cookies will become.
