Step 1: Crush the Cookies
Place the Oreo cookies in a food processor and pulse until finely crushed, resembling sand. This fine texture is key for the layered effect. Set them aside for assembly.
Step 2: Prepare the Cream Mixture
In a mixing bowl, blend the softened butter and cream cheese until smooth and lump-free. The mixture should be creamy and well combined, acting as the base for the pudding.
Step 3: Make the Pudding
In a large bowl, whisk the instant vanilla pudding mix with the milk until thickened. Gently fold in the Cool Whip to produce a lighter, fluffier consistency. This forms the bulk of your creamy layer.
Step 4: Combine for Ultimate Creaminess
Blend the cream cheese mixture with the pudding mixture, stirring until uniform. This combined mixture ensures every layer is consistently creamy and delightful.
Step 5: Layer the Trifle
In a trifle bowl, begin with a layer of crushed cookies, followed by a generous layer of the pudding mixture. Repeat, alternating layers, remembering to start and end with the cookies for a visually striking finish. Chill before serving for best results.
