First, start with your coffee. If you're using regular coffee instead of cold brew, make it stronger than usual and let it cool completely in the fridge for at least 2 hours. You can make this ahead of time the night before.

Once your coffee is cold, get your blender ready. Pour in 1 cup of the cold coffee, ½ cup unsweetened almond milk, and 2 tablespoons of heavy cream.

Add 1 teaspoon of your sweetener to start with. You can always add more later if you want it sweeter. Put in ½ teaspoon of vanilla extract too.

Now add 1 cup of ice cubes to your blender. If you want your drink thicker, you can add a few more ice cubes.

Cover your blender and start blending on low speed for about 10 seconds. This helps break up the ice cubes a bit.

Turn the speed up to high and blend for another 20-30 seconds until everything is smooth and frothy. You'll know it's ready when you don't hear any more ice chunks.

Take a small taste. If you want it sweeter, add another teaspoon of sweetener and blend for 5 more seconds.

Pour your frappe into a tall glass. Don't worry if it looks a bit foamy - that's exactly what you want!

If you like toppings, add some sugar-free whipped cream on top. You can sprinkle a little cocoa powder or add a drizzle of sugar-free chocolate syrup if you want.

Serve right away with a straw. The frappe tastes best when it's fresh and icy cold.
