1. Add heavy cream to stand mixer and whip on high speed until stiff peaks form.

2. In a large mixing bowl, add condensed milk and matcha powder. Whether you add 3 or 4 tbsp depends on how much you enjoy the matcha flavor. 4 tbsp will definitely be more intense and more of the bitter tea will come out, but I really enjoy the flavor of matcha so I prefer 4. Using a whisk, mix the condensed milk with matcha until smooth and no matcha powder lumps remain.

3. Using a spatula, gently fold in whipped cream until uniform. Fold in crushed Oreos, reserving about 3 tbsp.

4. Pour ice cream into a 9 x 5 loaf pan. Use a spatula to smooth and even out the surface. Sprinkle remaining crushes Oreos on top. Freeze overnight.
