Brownie Ice Cream Sandwiches

Thin, tender brownie layers hold creamy vanilla ice cream in bold frozen bars that stay pleasantly biteable straight from the freezer.

These brownie ice cream sandwiches turn a pan of fudgy brownies into a stack of clean-edged frozen bars. Baking the batter as one thin sheet gives every sandwich the same tender layer and avoids bulky corners that become hard in the freezer.

A combination of melted butter, neutral oil, and a little corn syrup keeps the brownie flexible even when thoroughly chilled. Dutch-process cocoa supplies deep chocolate flavor without adding chunks that would make the frozen bars difficult to bite.

The easiest assembly method is to cut the cooled brownie sheet into two equal slabs, spread softened ice cream over one, and place the second slab on top. The parchment sling helps move the layers without cracking them.

Freeze the filled slab until completely firm before cutting with a hot, dry knife. Individually wrapped bars keep well for several days and make a dramatic, practical addition to a celebratory summer dessert table.

Directions

  1. 1
    Rimmed sheet pan prepared with a parchment sling

    Heat the oven to 350°F. Lightly grease a 13-by-18-inch rimmed half-sheet pan, line the bottom and long sides with parchment, and lightly grease the parchment.

  2. 2
    Glossy brownie wet mixture with a whisk

    Whisk the melted butter, oil, corn syrup, and sugar in a large bowl until glossy. Add the eggs one at a time, then whisk in the vanilla until the mixture thickens slightly.

  3. 3
    Smooth chocolate brownie batter in a mixing bowl

    Sift the flour, cocoa, and salt over the wet mixture. Fold just until no dry streaks remain, taking care not to beat extra air into the batter.

  4. 4
    Thin brownie batter spread evenly in a sheet pan

    Spread the batter into a thin, even layer all the way to the pan corners. Bake for 14 to 16 minutes, until the surface is set and a tester comes out with moist crumbs; do not overbake.

  5. 5
    Trimmed brownie sheet cut into two equal slabs

    Cool completely in the pan, then lift out the brownie with the parchment. Trim any crisp outer edge and cut the sheet crosswise into two equal 9-by-13-inch slabs.

  6. 6
    Vanilla ice cream spread over a brownie slab in a lined pan

    Line a 9-by-13-inch pan with a wide parchment sling and place one brownie slab inside. Soften the ice cream for 8 to 10 minutes, spread it evenly over the brownie, and top with the second slab.

  7. 7
    Frozen brownie ice cream slab lifted from the pan

    Press the top gently to level the filling, cover the pan, and freeze until solid, at least 4 hours or overnight. Lift the frozen slab out using the parchment.

  8. 8
    Twelve cut brownie ice cream bars ready to wrap and freeze

    Warm a long knife under hot water and dry it well. Trim the edges, cut the slab into 12 rectangles, and wrap each bar tightly in parchment before freezing in an airtight container for up to 5 days.

Ingredients

  • Unsalted Butter, Melted:1/2 cup
  • Neutral Oil:1/4 cup
  • Light Corn Syrup:1/4 cup
  • Granulated Sugar:1 1/4 cups
  • Large Eggs:3
  • Pure Vanilla Extract:2 teaspoons
  • All-Purpose Flour:3/4 cup
  • Dutch-Process Cocoa Powder:3/4 cup
  • Fine Salt:1/2 teaspoon
  • Vanilla Ice Cream:1 1/2 quarts

Tips & Notes

  • Measure the sheet at the midpoint before cutting so the two brownie slabs align precisely.
  • If the ice cream becomes runny during assembly, freeze the bottom brownie and filling for 15 minutes before adding the top layer.
  • Clean and rewarm the knife between cuts to keep the brownie edges sharp and the ice cream layers distinct.
