These creamy Brown Sugar Oat Milk Espresso Popsicles are my new favorite way to get a caffeine fix and stay cool during the summer. Imagine the flavor of your favorite coffeehouse treat but in ice pop form—sweet brown sugar and cinnamon layers melding with rich espresso and silky oat milk for a perfect handheld dessert. These popsicles are dairy free gluten free vegetarian and incredibly easy to whip up even if you do not have any fancy coffee equipment.
Every time I bring out a batch of these popsicles they disappear fast especially during hot afternoons when everyone wants a treat without heating up the kitchen. They are also a fun twist for coffee fans who want something different.
Ingredients
- Oat milk: essential for a creamy base without dairy Choose unsweetened oat milk so the popsicles are not overly sweet and check the label if you need them to be gluten free
- Light brown sugar: brings that signature caramel sweetness and works well as a syrup Choose fresh soft brown sugar that is not clumpy or dried out for maximum flavor
- Cinnamon: adds warmth and makes the popsicles taste extra cozy Look for ground cinnamon with a strong scent
- Espresso: this is what gives the popsicles their grown up boost Use freshly brewed espresso or high quality instant espresso powder If you want less caffeine swap with strong coffee
- Vanilla extract: brightens everything and balances the other flavors A pure vanilla extract will give the best taste
- Water: used to dissolve the brown sugar and cinnamon to make a syrup Filtered water can help keep flavors clean
Step-by-Step Instructions
- Freeze the Oat Milk:
- Pour about two tablespoons of oat milk into the bottom of each of four popsicle molds Place the molds in the freezer and let the oat milk freeze for about one and a half hours This step creates a creamy first layer that contrasts with the coffee mini layers
- Make the Brown Sugar Syrup:
- Boil water in a small pot then remove from heat Add the brown sugar and cinnamon Whisk until the sugar is completely dissolved and the mixture is smooth Let it cool to room temperature The cinnamon may float but that is totally fine as it infuses the syrup with flavor
- Brew and Flavor the Espresso:
- Brew your espresso or brew strong coffee if you prefer Add the vanilla extract to the hot espresso Stir to combine and let the mixture cool to room temperature
- Layer Espresso Over Oat Milk:
- Once the oat milk layer is frozen pour the espresso mixture evenly into each popsicle mold over the oat milk
- Finish With Brown Sugar Syrup:
- Top off each popsicle mold with the brown sugar syrup Pour carefully so you do not overfill
- Freeze Until Solid:
- Insert popsicle sticks into each mold Place the molds flat in your freezer and let the popsicles freeze for at least six hours or overnight so they solidify completely

Brown sugar is my favorite ingredient here because it brings out the deep espresso notes and really makes these popsicles special The first time I made these my kids thought I had turned their favorite coffee shop order into dessert and now it is a summer ritual
Storage Tips
Once frozen run the molds under warm water for about twenty seconds to help release the popsicles Store each one in an individual freezer bag or wrap in plastic wrap to keep them from sticking together You will get the best texture and taste if you enjoy them within three months but they will keep for up to a year
Ingredient Substitutions
Try almond milk coconut milk or regular cream if you are not dairy free For a different twist swap cinnamon for cardamom or nutmeg Use strong brewed coffee instead of espresso for a lighter taste or even decaf if making for kids
Serving Suggestions
Serve these popsicles alongside a plate of summer fruit or sprinkle a little flaky salt on them for a grown up twist They are also perfect for backyard BBQs brunches or as a coffee break dessert on a hot afternoon

Cultural And Historical Context
