Use an electric hand mixer to combine the cream and vanilla in a large mixing bowl. Whip the cream on high speed until stiff peaks begin to form.
Once your whipped cream forms stiff peaks, lower the speed of your hand mixer and mix in the sweetened condensed milk, blackberries, raspberries, and blueberries. Mix until the fruit is evenly distributed throughout the ice cream.
In a small microwave safe bowl, melt the butter and then stir in the oats, brown sugar, and cinnamon. The oat mixture should resemble wet sand.
Transfer your ice cream to a 9x5 inch loaf pan and sprinkle the oat mixture on top. Cover your ice cream with plastic wrap and set it in the freezer for 5-6 hours, or until the center of the ice cream is firmly set.
Scoop, serve, and enjoy!
Notes
As long as you keep this ice cream covered with plastic wrap or transfer it to an airtight container, you can store it in the freezer for about 2 months.I like to use fresh berries since they break down a little more and become better distributed throughout the ice cream; however, you can use frozen berries in a pinch. Other fruit you can use include cherries, strawberries, peaches, and apples.For some extra spice flavor, add ½ tablespoon of cinnamon to your heavy cream before whipping it or to the whipped cream along with the sweetened condensed milk and fruit.Depending on how cold your freezer is you may need to let the ice cream sit a few minutes before scooping it. I found that I don’t often have to.This ice cream has the same texture as regular ice cream and scoops just the same.
