## Ingredients You’ll Need

* **Costco Blueberry Oat Milk:** The star of the show! This oat milk provides a subtle blueberry flavor and creamy texture. If you can’t find it at Costco, you can use another brand of blueberry oat milk or substitute with regular oat milk and add a few fresh or frozen blueberries (see substitutions below).
* **Matcha Powder:** Choose a high-quality culinary grade or ceremonial grade matcha powder for the best flavor and vibrant green color. Culinary grade is generally more affordable and perfectly suitable for lattes.
* **Hot Water:** For dissolving the matcha powder.
* **Sweetener (Optional):** Maple syrup, agave nectar, honey, or your favorite sugar substitute to taste.
* **Ice:** For iced lattes.

## Equipment

* **Small Bowl or Mug:** For whisking the matcha.
* **Whisk:** A bamboo matcha whisk (chasen) is ideal, but a small regular whisk works too. You can even use a milk frother with a whisk attachment.
* **Spoon or Measuring Spoons:** For measuring ingredients.
* **Glass or Mug:** For serving the latte.
* **Optional: Milk Frother:** To froth the oat milk for a creamier texture.

## Step-by-Step Instructions

Follow these simple steps to create your own Costco Blueberry Oat Milk Matcha Latte:

**Step 1: Prepare the Matcha Concentrate**

1. **Measure Matcha Powder:** Add 1-2 teaspoons of matcha powder to your small bowl or mug. The amount depends on your preferred matcha strength. Start with 1 teaspoon for a milder flavor and increase to 2 teaspoons for a bolder taste.
2. **Add Hot Water:** Pour 2-3 tablespoons of hot water (not boiling) over the matcha powder. The water should be around 175°F (80°C).
3. **Whisk Vigorously:** Use your whisk to vigorously whisk the matcha and water together until a smooth, frothy paste forms. There should be no clumps of matcha powder remaining. If using a traditional bamboo whisk, use a back-and-forth “W” or “M” motion. This step is crucial for preventing a gritty texture.

**Step 2: Assemble the Latte (Iced)**

1. **Fill Glass with Ice:** Fill your serving glass with ice cubes.
2. **Pour in Blueberry Oat Milk:** Pour the Costco Blueberry Oat Milk (or your chosen substitute) over the ice, leaving about 1-2 inches of space at the top.
3. **Sweeten (Optional):** If desired, add your sweetener of choice to the oat milk and stir well.
4. **Pour in Matcha Concentrate:** Slowly pour the prepared matcha concentrate over the oat milk. For a layered effect, pour it gently over the back of a spoon held close to the surface of the oat milk.
5. **Stir and Enjoy:** Gently stir the latte to combine the matcha and oat milk before drinking. If you prefer a more integrated flavor, stir more vigorously.

**Step 2: Assemble the Latte (Hot)**

1. **Heat Blueberry Oat Milk:** Gently heat the Costco Blueberry Oat Milk (or your chosen substitute) in a saucepan or microwave until warm, but not boiling. Be careful not to scald the milk.
2. **Froth the Milk (Optional):** If you have a milk frother, froth the heated oat milk to create a creamy, foamy texture. This step enhances the latte’s richness. If you don’t have a frother, you can whisk the milk vigorously by hand to create some foam.
3. **Pour Warm Milk into Mug:** Pour the warm, frothed (or whisked) oat milk into your serving mug, leaving about 1-2 inches of space at the top.
4. **Sweeten (Optional):** If desired, add your sweetener of choice to the oat milk and stir well.
5. **Pour in Matcha Concentrate:** Slowly pour the prepared matcha concentrate over the oat milk. For a latte art effect, you can try pouring it in a swirling motion.
6. **Enjoy Immediately:** Sip and savor your warm and comforting Costco Blueberry Oat Milk Matcha Latte.

## Tips for the Perfect Latte

* **Matcha Quality Matters:** Invest in a good quality matcha powder for the best flavor and color. Look for matcha that is vibrant green and has a slightly sweet, vegetal aroma. Avoid dull or brownish matcha, which may be old or of lower quality.
* **Whisking is Key:** Properly whisking the matcha powder is essential for preventing clumps and ensuring a smooth, even texture. Don’t skip this step!
* **Adjust Sweetness to Your Liking:** Start with a small amount of sweetener and add more to taste. Remember that the blueberry oat milk already has some sweetness.
* **Experiment with Milk Ratios:** Adjust the ratio of oat milk to matcha concentrate to find your perfect balance. Some people prefer a stronger matcha flavor, while others prefer a creamier latte.
* **Temperature Matters:** Avoid using boiling water for the matcha, as it can make it taste bitter. Use water that is just below boiling (around 175°F or 80°C).
* **Layering Technique:** For a visually appealing layered effect, pour the matcha concentrate slowly over the back of a spoon held close to the surface of the oat milk.
* **Garnish (Optional):** Add a sprinkle of matcha powder, a few fresh blueberries, or a dusting of cinnamon for an extra touch of elegance.

## Substitutions and Variations

* **Blueberry Oat Milk Substitute:** If you can’t find Costco’s Blueberry Oat Milk, you can use regular oat milk and add a handful of fresh or frozen blueberries to a blender. Blend until smooth and strain the mixture through a fine-mesh sieve to remove any pulp. Alternatively, you can use another brand of blueberry oat milk.
* **Milk Alternatives:** Feel free to use other milk alternatives, such as almond milk, soy milk, or coconut milk. Keep in mind that the flavor will be slightly different.
* **Sweetener Options:** Experiment with different sweeteners, such as maple syrup, agave nectar, honey, or your favorite sugar substitute. You can also use flavored syrups, such as vanilla or caramel.
* **Vanilla Extract:** Add a few drops of vanilla extract to the oat milk for a richer flavor.
* **Cinnamon or Nutmeg:** Sprinkle a pinch of cinnamon or nutmeg on top of the latte for a warm and comforting flavor.
* **Lavender:** Add a few drops of lavender syrup or a pinch of dried lavender to the oat milk for a floral twist.
* **Matcha Varieties:** Explore different types of matcha powder, such as ceremonial grade matcha, which has a smoother and more delicate flavor.
* **Espresso Shot:** For an extra caffeine boost, add a shot of espresso to your latte.
* **Protein Powder:** Add a scoop of your favorite protein powder for a post-workout treat.
