Line the bottom of a 9-inch springform pan with parchment paper and lightly grease the sides. This helps the chilled cake release without tearing the edges.
02 -
Beat the cold heavy cream, powdered sugar, vanilla, almond extract, and salt on medium-high speed until stiff peaks form, about 3-5 minutes.
03 -
In a separate large bowl, beat the softened cream cheese until smooth and fluffy, about 1 minute. Scrape the bowl so no dense pockets remain.
04 -
Fold the whipped cream into the cream cheese in two additions until no streaks remain. Gently fold in the rainbow sprinkles at the end.
05 -
Dip each Oreo quickly into milk, then arrange a snug layer in the pan. Spread with about one quarter of the filling. Repeat with more cookies and filling until you have four cookie layers, ending with filling on top.
06 -
Cover the pan and refrigerate for at least 6 hours, or overnight for the cleanest slices. The cookies should be soft all the way through.
07 -
Run a thin knife around the edge, release the springform ring, and transfer the cake to a serving plate. Top with whipped cream and extra sprinkles just before slicing.
