Full Ingredients

For the Maple–Brown Sugar Oat Milk Steamer

• 1 1/2 cups (360 ml) unsweetened oat milk, barista or extra-creamy preferred
• 1 1/2 tablespoons (22 ml) pure maple syrup
• 1 tablespoon (12 g) packed light brown sugar
• 1/4 teaspoon pure vanilla extract
• 1/8 teaspoon ground cinnamon
• 1 small pinch ground nutmeg (optional, for extra bakery-style aroma)
• 1 small pinch fine sea salt (just enough to enhance the sweetness)

Optional Toppings

• 2–3 tablespoons oat or coconut whipped topping
• Ground cinnamon or nutmeg, for dusting
• Extra maple syrup, for drizzling
• Thin strip of orange peel, twisted, for garnish (optional)

Step-by-Step Instructions

Step 1: Prep your mug and measure ingredients

Fill your serving mug with very hot tap water to warm it up; this helps the drink stay hot longer. Set it aside while you prepare the steamer. Measure out the oat milk, maple syrup, brown sugar, vanilla, cinnamon, nutmeg (if using), and salt so everything is ready to go. Having everything measured before you start heating helps prevent the milk from overheating while you hunt for ingredients.

Step 2: Combine oat milk, maple, and brown sugar

In a small saucepan, add the oat milk, maple syrup, brown sugar, ground cinnamon, nutmeg (if using), and the pinch of salt. Do not add the vanilla yet; it is best added at the end so its flavor stays fragrant and bright. Whisk the mixture briefly to dissolve the sugar and evenly distribute the spices. The surface should look mostly smooth, with no big clumps of brown sugar.

Step 3: Warm gently until steamy (but not boiling)

Place the saucepan over medium-low heat. Warm the mixture, stirring or whisking occasionally, until it is hot and steaming but not boiling, 4–6 minutes. If you have an instant-read thermometer, aim for 160–170°F (71–77°C). Avoid letting the oat milk boil hard; boiling can cause it to thicken or split, which affects both texture and taste. If you see bubbles forming around the edges or it starts to simmer vigorously, lower the heat immediately.

Step 4: Add vanilla and froth the milk

Remove the pan from the heat. Stir in the vanilla extract. Taste a small spoonful (carefully; it is hot) and adjust sweetness or spice if needed, adding a bit more maple or cinnamon to your liking. Now froth the milk: use a handheld milk frother directly in the pan for 20–30 seconds, or whisk vigorously by hand until a thin layer of foam forms. Alternatively, pour the hot mixture into a heat-safe jar, seal loosely, and shake with a kitchen towel wrapped around it for 20–30 seconds, then carefully open (steam will escape).

Step 5: Pour, garnish, and build that café look

Dump the warming water from your mug and dry it quickly. Pour the hot steamer into the mug, holding back the foam with a spoon. Then spoon the frothed layer on top for a café-style finish. If using, add a swirl of oat or coconut whipped topping. Lightly dust the surface with a pinch of ground cinnamon or nutmeg, and optionally drizzle 1–2 teaspoons of maple syrup in a loose spiral. For a bakery-style flourish, twist a thin strip of orange peel over the mug to release its oils, then rest it on the rim.

Step 6: Serve at the perfect sipping temperature

Serve the maple–brown sugar oat milk steamer immediately while it is still piping hot and aromatic. The ideal sipping temperature is just cool enough that you can comfortably hold the mug and take small, steady sips without burning your tongue. Enjoy it on its own as a cozy treat, or pair it with a simple cookie or slice of toast for a full bakery-at-home moment. Because oat milk can form a light skin as it cools, give the drink a quick stir if it sits for more than a few minutes.

Pro Tips

• Choose barista-style oat milk: Barista or “extra creamy” varieties foam better and give you that silky coffee-shop texture.
• Do not let it boil: Oat milk can separate or get gummy if boiled. Pull it off the heat as soon as it is steamy and hot.
• Adjust sweetness gradually: Start with the listed amounts, then add extra maple syrup 1 teaspoon at a time to avoid over-sweetening.
• Use fresh spices: Freshly opened cinnamon and nutmeg make a huge difference to that warm, bakery-inspired aroma.
• No frother? Use a French press: Pour the hot milk into a clean French press and pump the plunger up and down 10–15 times to create foam.

Variations

• Dirty Maple Oat Steamer: Add 1 shot (1–2 oz) of freshly brewed espresso or very strong coffee to the mug before pouring in the hot oat milk mixture. This turns it into a cozy, lightly sweet maple latte.
• Maple Chai Steamer: Replace the ground cinnamon and nutmeg with 1/4–1/2 teaspoon chai spice blend, or steep a chai tea bag in the hot mixture (off heat) for 3–5 minutes before frothing.
• Extra-Salted Maple: Increase the sea salt to a small but noticeable pinch and drizzle a little extra maple syrup on top for a salted-maple effect reminiscent of salted caramel drinks.

Storage & Make-Ahead

This drink is best enjoyed fresh, right after frothing, when the texture is at its creamiest and the spices are most aromatic. However, you can make a small batch of the base in advance:

To prep ahead, mix the oat milk, maple syrup, brown sugar, cinnamon, nutmeg, and salt in a jar and refrigerate for up to 3 days. When ready to serve, shake well, then heat gently on the stovetop or in the microwave until hot and steaming (do not boil). Stir in the vanilla, froth, and serve as directed. Leftover prepared steamer (already heated) can be cooled, refrigerated for up to 24 hours, and reheated gently, though the texture will be slightly less velvety and you will want to re-froth it before serving.
