First, prep your ice cream base and lemon bars. You can use a box mix, homemade, or lemon bars from a bakery. They will be cut into small pieces. Your ice cream bowl needs to be kept in the freezer overnight before using.
For your ice cream base, combine ingredients, and mix until sugar is dissolved. Sometimes it's easier to add the heavy cream last after the sugar has dissolved. Add in your lemon bar pieces.
Place ice cream base in fridge for at least an hour—overnight works best.
Turn ice cream maker on and the pour in your ice cream mixture. Let stir for 20 minutes, then add your fresh lemon juice and pretzel pieces. Let machine run for another 5-10 minutes.
Store in an airtight container in your freezer or enjoy right away!
