The Ultimate Homemade Oreo Ice Cream Sandwiches

A child's hands holding a large, homemade Oreo Ice Cream Sandwich on a summer day.

A homemade, no-bake recipe for thick Oreo ice cream sandwiches made in a square pan. The dessert features a top and bottom layer made from a simple crust of crushed Oreo cookies and melted butter. The filling is a creamy, no-churn ‘cookies and cream’ ice cream, created by folding crushed Oreos into a mixture of sweetened condensed milk and freshly whipped cream. The entire block is frozen solid and then sliced into individual rectangular sandwiches.

Ingredients

Scale
  • 600 g (about 50) whole Oreo cookies
  • 170 g (about 3/4 cup) unsalted butter, melted
  • 500 g (about 2 cups) heavy cream
  • 1 tablespoon vanilla extract
  • 150 g (about 1/2 cup) condensed milk

Instructions

  1. Line a 9×9-inch square pan with parchment paper, leaving an overhang on the sides to act as handles.
  2. In a food processor, pulse the Oreo cookies into fine crumbs. Set aside 100g (about ½ cup) of the crumbs for the filling.
  3. Transfer the rest of the Oreo crumbs to a medium bowl. Add the melted butter and stir until the mixture resembles wet sand.
  4. Press half of the buttered crumb mixture into the bottom of the prepared pan in a flat, even layer. Place the pan in the freezer to chill.
  5. Make the Filling: In a large mixing bowl, use an electric mixer to whip the heavy cream and vanilla extract until stiff peaks form.
  6. Slowly pour in the condensed milk while gently folding with a spatula until no streaks remain.
  7. Fold in the 100g of reserved Oreo crumbs until just combined.
  8. Assemble and Freeze: Pour the ice cream mixture over the chilled Oreo crust and smooth it into an even layer. Freeze for 1-2 hours, until the surface is firm to the touch.
  9. Gently spread the remaining Oreo crust mixture on top of the firm ice cream layer and press it down into a flat, even layer.
  10. Freeze for at least 6 more hours, or preferably overnight, until completely solid.
  11. To serve, use the parchment paper handles to lift the block out of the pan. Run a sharp knife under hot water, wipe it dry, and cut the block into 8 rectangular sandwiches.
  12. Serve immediately or wrap individually and return to the freezer.

Notes

  • Using a parchment paper sling in the pan is a key step that makes it easy to remove the frozen block for cutting.
  • The ice cream layer needs to be partially frozen before adding the top crust to prevent it from mixing in.
  • The long final freeze of at least 6 hours is crucial for the sandwiches to become firm enough to slice cleanly.
  • Running your knife under hot water before each cut will help you make neat, clean slices.
