Blend strawberries until smooth. Transfer to a container.
Prepare the simple syrup. Add sugar and water to a pot. Bring to a boil. Lower heat and simmer until sugar is dissolved. Let cool. Add simple syrup to the blended strawberries. If you don’t like things very sweet, add a little bit at a time to taste. Add lime juice and stir.
Prepare the crumbs. In a bowl, combine all ingredients. Spread on a parchment-lined baking sheet and bake for 10-12 minutes, until lightly golden. Let cool completely.
Scoop a couple of small scoops of ice cream into each cavity of the popsicle molds.
Spoon the strawberry mixture into the molds to fill the gaps. Smooth using an offset spatula. Freeze for 15-20 minutes then sprinkle with streusel. Freeze until firm.
Once pops are firm, you can transfer them to a different container and use your molds again.
