Method
Heat-Treat the Flour (for edible dough)
- Spread all-purpose flour on a sheet pan in an even thin layer and bake at 350F for 5 minutes. Let the flour cool completely so it won’t melt the butter.
Make the Cookie Dough
- Beat softened unsalted butter, brown sugar, and granulated sugar until fluffy. Mix until the mixture looks lighter in color and holds ridges.
- Add whole milk, vanilla extract, and salt, then mix until smooth. Scrape the sides to make sure everything is fully incorporated.
- Stir in the heat-treated all-purpose flour until a dough forms. Fold until no dry flour remains.
- Fold in mini chocolate chips evenly throughout the dough. The dough should be thick and studded with chips.
Freeze Dough Layers
- Divide the dough in half and press each half into a parchment-lined 9x13 pan in an even 1/2-inch layer. Keep the surface level for clean sandwich slices.
- Freeze both dough layers for 30 minutes until firm. They should feel set and not bend when nudged.
Assemble and Freeze
- Spread a 1-inch layer of slightly softened vanilla ice cream over one frozen dough layer. Leave a small border so it doesn’t squeeze out too much at the edges.
- Carefully flip the second frozen dough layer on top of the ice cream. Align the edges and set it down gently so the ice cream doesn’t smear.
- Press gently to help the layers adhere. Freeze at least 2 hours until completely firm.
Slice and Serve
- Slice into rectangles using a warm knife. Serve immediately for the cleanest layers and best texture.
- Wrap individually if not serving right away. Freeze any leftovers until needed, and thaw briefly for easier bites.
Notes
Pro tip: bake and cool the flour fully before mixing—warm flour can melt butter and make dough too soft. Store assembled sandwiches covered in the freezer for up to 2 weeks; for best texture, keep parchment between layers. Freezer yes—do not refrigerate for extended time. Dietary swap: use a 1:1 gluten-free all-purpose flour blend labeled for baking and heat-treat it the same way for a gluten-free version.
