Line the bottom of the baking pan with parchment paper - leave the sides empty.
Step 2 - preparing the meringues
Prepare two meringue layers separately - if you have two identical pans, you can bake them at the same time.
Briefly whisk the egg whites until they are slightly fluffy.
2 x 2 egg whites
Add sugar to them in portions, mixing on high speed with a mixer - mix until you get smooth, white egg whites and all the sugar has dissolved (you won't feel sugar crystals).
2 x 100 g sugar
Add potato flour and lemon juice to the egg whites - mix briefly.
2 x 0.5 teaspoons potato starch, 2 x 0.5 teaspoons lemon juice
Spread the meringue into the pan and level it.
Place in the hot oven and bake for about an hour.
After baking, trim the meringue, remove it from the pan, and prepare the second meringue layer as before.
Cool the meringues completely.
Step 3 - prepare the Oreo cream
Transfer the cream cheese to a bowl and briefly mix with powdered sugar.
250 g mascarpone cheese, 2 tablespoons powdered sugar
Add the heavy cream in portions and mix on high speed until you get a thick cream.
250 ml heavy cream
Add powdered milk and briefly mix.
50 g milk powder
Coarsely chop the cookies.
approx. 100 g dark cookies
Add the cookies to the cream and mix with a spoon.
Step 4 - assembling the cake
Spread the cream with cookies onto the meringue base placed in the mold and level it.
Place the second meringue layer, using the baking paper it was baked on to help (don't worry if the meringue cracks slightly).
Step 5 – Preparing the whipped cream.
Whip the heavy cream together with the sugar until it forms thick whipped cream.
250 ml heavy cream, 2 tablespoons powdered sugar
Spread the whipped cream on top of the cake.
Put the cake in the refrigerator for about 2–4 hours.
