Ingredients:
- For the Oatmeal Cookie Syrup:
- 1 cup rolled oats (old-fashioned or quick-cooking)
- 1 cup water
- 1/2 cup packed brown sugar
- 1/4 cup granulated sugar
- 1 teaspoon vanilla extract
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg
- Pinch of salt
- For the Cold Brew Coffee:
- 1 cup coarsely ground coffee beans (medium-dark roast recommended)
- 4 cups cold, filtered water
- For Assembling the Oatmeal Cookie Cold Brew:
- Ice cubes
- Oat milk (or your preferred milk)
- Whipped cream (optional)
- Oatmeal cookie crumbles (optional, for garnish)
- Cinnamon sprinkle (optional, for garnish)
Making the Cold Brew Coffee Concentrate:
Okay, let’s start with the cold brew. This needs to steep for a while, so it’s best to get this going first. Don’t worry, it’s super easy!
- Combine Coffee and Water: In a large jar or pitcher, combine the coarsely ground coffee beans and cold, filtered water. Make sure all the grounds are submerged. I like to give it a good stir with a long spoon to ensure everything is mixed well.
- Steep in the Refrigerator: Cover the jar or pitcher and refrigerate for 12-24 hours. The longer it steeps, the stronger the coffee will be. I usually go for 18 hours for a nice, robust flavor.
- Strain the Coffee: After steeping, strain the coffee concentrate through a fine-mesh sieve lined with cheesecloth or a coffee filter. This will remove all the coffee grounds and leave you with a smooth, concentrated cold brew. You might need to strain it twice to get rid of all the sediment. Don’t skip this step; nobody wants gritty coffee!
- Store the Concentrate: Store the cold brew concentrate in an airtight container in the refrigerator for up to two weeks. Remember, this is a concentrate, so you’ll need to dilute it with water or milk when you’re ready to drink it.
Preparing the Oatmeal Cookie Syrup:
Now for the star of the show the oatmeal cookie syrup! This is where the magic happens. It’s surprisingly simple to make and adds that warm, comforting oatmeal cookie flavor to your cold brew.
- Toast the Oats (Optional but Recommended): This step is optional, but I highly recommend it! Toasting the oats brings out their nutty flavor and adds depth to the syrup. Spread the rolled oats in a single layer on a baking sheet and bake in a preheated oven at 350°F (175°C) for 5-7 minutes, or until lightly golden and fragrant. Watch them carefully, as they can burn quickly. Alternatively, you can toast them in a dry skillet over medium heat, stirring frequently, until lightly golden.
- Combine Ingredients in a Saucepan: In a medium saucepan, combine the toasted oats (or untoasted if you skipped the toasting step), water, brown sugar, granulated sugar, vanilla extract, cinnamon, nutmeg, and salt.
- Simmer the Mixture: Bring the mixture to a simmer over medium heat, stirring occasionally to dissolve the sugars. Once simmering, reduce the heat to low and continue to simmer for 15-20 minutes, or until the syrup has thickened slightly and the oats have softened. Stir occasionally to prevent sticking.
- Strain the Syrup: Remove the saucepan from the heat and let the syrup cool slightly. Then, strain the syrup through a fine-mesh sieve lined with cheesecloth or a nut milk bag to remove the oats. This will give you a smooth, clear syrup. Press down on the oats with a spoon to extract as much syrup as possible.
- Cool and Store: Let the syrup cool completely before transferring it to an airtight container. Store the syrup in the refrigerator for up to two weeks. The syrup will thicken slightly as it cools.
Assembling Your Oatmeal Cookie Cold Brew:
Alright, we’ve got our cold brew concentrate and our delicious oatmeal cookie syrup. Now it’s time to put it all together and enjoy our creation!
- Fill a Glass with Ice: Fill a glass with ice cubes. The amount of ice you use will depend on your preference, but I usually fill the glass about two-thirds full.
- Add Oatmeal Cookie Syrup: Pour 2-3 tablespoons of oatmeal cookie syrup into the glass. Adjust the amount to your liking, depending on how sweet you want your cold brew. I recommend starting with 2 tablespoons and adding more if needed.
- Add Cold Brew Concentrate: Pour 1/4 cup of cold brew concentrate into the glass. Again, adjust the amount to your preference. If you want a stronger coffee flavor, add more concentrate. If you want a milder flavor, add less.
- Top with Milk: Top the glass with oat milk (or your preferred milk). Leave some room at the top for whipped cream and garnish, if desired.
- Stir Well: Stir the mixture well to combine the syrup, cold brew, and milk. Make sure the syrup is evenly distributed throughout the drink.
- Add Whipped Cream (Optional): If you’re feeling fancy, top your cold brew with a dollop of whipped cream.
- Garnish (Optional): For an extra touch of oatmeal cookie goodness, sprinkle some oatmeal cookie crumbles and cinnamon on top of the whipped cream (or directly onto the drink if you’re skipping the whipped cream).
- Enjoy! Take a sip and enjoy your delicious, homemade Oatmeal Cookie Cold Brew!
Tips and Variations:
- Adjust Sweetness: The sweetness of this drink is easily adjustable. If you prefer a less sweet drink, reduce the amount of sugar in the syrup or use less syrup in your cold brew.
- Use Different Milk: Feel free to use any type of milk you like. Almond milk, soy milk, coconut milk, or regular dairy milk all work well.
- Add a Shot of Espresso: For an extra caffeine kick, add a shot of espresso to your cold brew.
- Make it Vegan: To make this recipe completely vegan, use plant-based milk and vegan whipped cream.
- Oatmeal Cookie Crumble Recipe: If you want to make your own oatmeal cookie crumbles, simply bake a batch of your favorite oatmeal cookies and crumble them up after they’ve cooled. You can also buy pre-made oatmeal cookies and crumble them.
- Spice it Up: Add a pinch of ground ginger or cloves to the syrup for a warmer, spicier flavor.
- Chocolate Oatmeal Cookie Cold Brew: Add a tablespoon of cocoa powder to the syrup while it’s simmering for a chocolatey twist.
- Make a Large Batch: You can easily double or triple the syrup recipe to make a larger batch. Just be sure to store it in an airtight container in the refrigerator.
Troubleshooting:
- Syrup Too Thick: If your syrup is too thick, add a little water to thin it out.
- Syrup Too Thin: If your syrup is too thin, simmer it for a few more minutes to allow it to thicken.
- Coffee Too Bitter: If your cold brew is too bitter, try steeping it for a shorter amount of time or using a lighter roast coffee.
- Coffee Too Weak: If your cold brew is too weak, try steeping it for a longer amount of time or using a darker roast coffee.
