Whisk together the condensed milk, vanilla extract, and salt in a mixing bowl. Set aside.
In a large bowl, whip the heavy cream using a hand mixer or stand mixer with a whisk attachment until stiff peaks form. When stiff peaks form, the heavy cream will hold a defined shape when you pull the whisk out of the cream.
Gently fold the condensed milk mixture into the whipped cream using a spatula. Move the spatula down the middle of the bowl, then scoop and turn it over, drawing a lazy number 8 motion. You may need to rotate the bowl a bit, and fold until everything is fully incorporated and cohesive.
Pour half of the mixture into a loaf pan or similar freezer-safe container. Sprinkle half of the crushed mini eggs over the top. Pour the rest of the mixture on top. Then, sprinkle with remaining crushed mini eggs.
Press parchment paper directly on top of the ice cream, then top with an airtight lid or wrap with plastic wrap. Freeze for at least 4 hours.
When ready to serve, let it sit at room temp for 3-5 minutes to soften and make scooping easier. Keeps fresh for 1-2 weeks covered tightly in the freezer for best texture and taste.
Notes
Tips:
To easily crush your mini eggs, place them in a ziplock bag and use a rolling pin to crush them.
Fold the condensed milk mixture into the whipped cream gently - don't use a lot of force. This helps maintain an airy texture.
For a nutty twist, swap the vanilla extract with almond extract.
Swirl in some melted chocolate or fruit compote before freezing.
To add a coffee kick, whisk in a packet or spoonful of instant coffee or espresso into the sweetened condensed milk mixture.
