Homemade Irish Cream

Apparently a few years ago I had jotted down this recipe in a little notebook that I keep in the kitchen, but I don't recall ever trying it. I decided to try it today, and it is quite tasty! It doesn't taste like Bailey's, but it should work well as a boozy addition to coffee.
Also, it's a lot cheaper than buying a bottle of Bailey's. (It might not be cheaper than a bottle of O'Mara's.)

Edited to add: after it cooled down, I really didn't like it. It might be the sugar substitute, but I'm not sure. Even after I added it to coffee, I didn't like it. I'll be looking around for other recipes.

Edit #2: I added some whole milk and chocolate syrup (with sugar, not sugar substitute) and it's much better now. I wouldn't drink it on its own, but it's great in coffee.

Homemade Irish Cream

Ingredients
1 cup heavy cream (next time I'll try it with half-and-half, as it's bit thicker than I would like)
1/3 to 2/3 cup whiskey (I only used 1/3 cup, as I didn't have much whiskey left.)
1/2 teaspoon instant coffee
1.5 teaspoons cocoa powder
1/2 teaspoon vanilla
1/4 teaspoon almond extract
1/3 cup sugar (or sugar substitute) -- I used Stevia in the Raw

Heat cream on low. Add other ingredients. Whisk gently until everything is fully dissolved. KEEWERD
