Blueberry cobbler ice cream combines creamy vanilla ice cream with swirls of sweet blueberry sauce and chunks of buttery, crumbly cobbler crust. Beat the summer heat with this decadent treat that's bursting with blueberry flavor, it'll quickly become your favorite flavor!
Prepare the blueberry filling by combining blueberries, sugar, and lemon juice in a small saucepan over medium heat. Bring to a boil and boil for 2-3 minutes, then reduce to a simmer and allow the mixture to reduce for 10-15 minutes, until thickened.
Combine cornstarch and water in a small bowl and mix together to form a slurry. Add to the blueberry sauce, and continue to cook for 3-5 minutes, stirring constantly to cook off the cornstarch taste. The mixture will thicken quickly.
Remove from the heat and Add lemon zest and mix together until combined. Set aside to cool completely.
Combine melted butter, sugar, cinnamon, vanilla extract, and a pinch of salt in a medium sized bowl. Mix together with a spoon or whisk, then add the flour and mix together with your fingers, pinching together until crumbles begin to form.
Place mixture onto a parchment lined baking sheet, scattering the crumbles all about the pan. Bake for 15-20 minutes, until the crumbles become golden. Allow to cool completely on the baking sheet, as the crumbles cool, they’re harden into cookie-like pieces.
Let the Lactaid Ice Cream sit at room temperature for about 20-30 minutes, to melt just slightly and make swirling everything together easier.
Add 1 quart of Lactaid ice cream to a 9x5 loaf pan OR 9-inch round baking pan (that’s at least 3-inches deep) lined with parchment paper. Add half of the blueberry sauce and a generous amount of the crumble. Use a butter knife or skewer to swirl everything together. Add another layer of crumble on top.
Add the remaining ice cream on top and repeat step #8.
