Ingredients
Scale
- 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
- 1 cup coarsely ground coffee beans (medium-dark roast recommended)
- 4 cups cold, filtered water
- Ice cubes
- Oat milk (or your preferred milk)
- Whipped cream (optional)
- Oatmeal cookie crumbles (optional, for garnish)
- Cinnamon sprinkle (optional, for garnish)
Instructions
- 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. Stir well.
- Steep in the Refrigerator: Cover and refrigerate for 12-24 hours (18 hours recommended for robust flavor).
- Strain the Coffee: Strain the coffee concentrate through a fine-mesh sieve lined with cheesecloth or a coffee filter. Strain twice to remove all sediment.
- Store the Concentrate: Store the cold brew concentrate in an airtight container in the refrigerator for up to two weeks.
- Toast the Oats (Optional but Recommended): 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. 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. 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.
- Fill a Glass with Ice: Fill a glass with ice cubes.
- Add Oatmeal Cookie Syrup: Pour 2-3 tablespoons of oatmeal cookie syrup into the glass. Adjust the amount to your liking.
- Add Cold Brew Concentrate: Pour 1/4 cup of cold brew concentrate into the glass. Adjust the amount to your preference.
- Top with Milk: Top the glass with oat milk (or your preferred milk).
- Stir Well: Stir the mixture well to combine the syrup, cold brew, and milk.
- Add Whipped Cream (Optional): Top your cold brew with a dollop of whipped cream.
- Garnish (Optional): 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!
Notes
- Adjust Sweetness: Adjust the amount of sugar in the syrup or use less syrup in your cold brew.
- Use Different Milk: 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: Use plant-based milk and vegan whipped cream.
- Oatmeal Cookie Crumble Recipe: Bake a batch of your favorite oatmeal cookies and crumble them up after they’ve cooled.
- Spice it Up: Add a pinch of ground ginger or cloves to the syrup.
- Chocolate Oatmeal Cookie Cold Brew: Add a tablespoon of cocoa powder to the syrup while it’s simmering.
- Make a Large Batch: Double or triple the syrup recipe.
- Syrup Too Thick: Add a little water to thin it out.
- Syrup Too Thin: Simmer it for a few more minutes to allow it to thicken.
- Coffee Too Bitter: Steep it for a shorter amount of time or using a lighter roast coffee.
- Coffee Too Weak: Steep it for a longer amount of time or using a darker roast coffee.
