Extra-strong espresso, sweet condensed milk, and coffee liqueur are the perfect adult coffee drink when it’s hot out—even better if they’re frozen into shot-size servings. Get our Spiked Frozen Coffee Shots recipe.

2. Chocolate Peanut Butter Cups (& Other Filled Chocolates)

You can always count on Chocolate Covered Katie to have a great chocolate-y idea. This simple one makes two-bite peanut butter cups in an ice cube tray—but the same trick also works for other filled chocolates, like the no-bake cheesecake bites shown above, or chocolate-covered cookie dough bites, just for starters. Get the Ice Cube Tray Chocolate Peanut Butter Cups recipe.

3. Buttermilk Cubes

One of life’s biggest hoaxes is the big containers of buttermilk at the grocery store that you’re forced to buy when you only need a tiny bit for one recipe. It’s such a shame to let the rest go bad. So don’t. Get the Buttermilk Cubes recipe (sort of).

4. Pesto Cubes

Save the pesto! Once your basil plant gets going, it seems like it won’t quit. So the next time you make pesto, double the recipe and freeze half of it. You can pop out the cubes to store in a freezer bag for single servings or whatever amount you need. Get the Pesto Cubes recipe.

5. Broth or Stock Cubes

6. Herb Oil Cubes

When you have fresh herbs that you can’t use up in time, or your plant is growing so many you can’t use and give away enough, do this. Freeze your chopped fresh herbs in butter or olive oil. Get the Herb Oil Cubes recipe.

Unlike those spiked shots, this is for your everyday coffee before work when it’s hot out and you want iced coffee that’s not watered down. Get the Iced Coffee Cubes recipe (sort of). Perfect for keeping your cold brew chill.

8. Ravioli

You can even use an ice cube tray as a ravioli mold if you want to venture into homemade pasta without investing in special equipment (when it comes to ravioli molds, at least).

9. Cookie Dough

Pop raw cookie dough of any kind into an ice cube tray and freeze it—so when a sweet craving hits, you can simply pop out one or two frozen dough nuggets and bake them for a quick fix.

10. Wine Ice Cubes

Not only are these great for chilling your sangria without diluting it, they can be used for cooking too—stash them in your freezer and throw one in a hot pan to deglaze, or add to a stew or braise when you don’t want to open an entire bottle just for your recipe. This is an especially good way to deal with any leftover wine (people swear that’s a thing) or a bottle you don’t love enough to finish drinking but don’t hate enough to pour down the drain.

11. Flower Ice Cubes

Sometimes there’s no need to completely reinvent the wheel—just tweak it a little. Distilled water and edible flowers (with no pesticides, please) can make your spring and summer more beautiful, one spiked lemonade and iced tea at a time. Get the Flower Ice Cubes recipe.
