1-First Step: Chill a large mixing bowl in the freezer for 10 minutes. Gather all ingredients: measure condensed milk, cookie butter, and crush half the Biscoff cookies into fine crumbs using a food processor or zip-top bag and rolling pin. Separate the remaining cookies for assembly later. This setup keeps everything efficient.

2-Second Step: Whip the cream. Remove the chilled bowl and pour in the cold heavy whipping cream. Use an electric mixer on medium-high speed to beat until stiff peaks form, about 3-4 minutes. Avoid overwhipping to prevent butter-like texture. Gently fold in the sweetened condensed milk and 1 cup Biscoff spread until smooth streaks disappear, taking care not to deflate the whipped cream.

3-Third Step: Add crunch and spice. Fold in the 1/2 cup crushed Biscoff cookies evenly. Taste and adjust with a bit more cookie butter if you crave extra lotus biscoff punch. Spoon the mixture into a loaf pan lined with parchment paper. Smooth the top, cover tightly with plastic wrap pressed directly on the surface to avoid freezer burn, then freeze for at least 6 hours or overnight until firm like store-bought ice cream.

4-Fourth Step: Check doneness. The ice cream is ready when a spoon scoops clean edges without melting quickly. If it’s too hard, let it sit at room temperature for 5-10 minutes. For best texture in your ice cream sandwiches, aim for scoopable but solid consistency.

5-Fifth Step: Scoop and sandwich. Use a cookie scoop or large spoon to portion 2-3 tablespoons of biscoff ice cream onto the flat side of one Biscoff cookie. Top with another cookie, pressing gently to spread the ice cream to the edges. Repeat for all. For uniform size, use an ice cream scoop dipped in hot water.

6-Final Step: Finishing touches and serving. Roll the edges in extra crushed Biscoff cookies for a pro look. Place on a parchment-lined tray and freeze for 1-2 more hours to set. Serve straight from freezer or let soften 2 minutes for easier biting. Pair with coffee for busy parents or as a post-dinner treat for food enthusiasts. Store extras as noted below.
