Agua de Avena (Oat Horchata)

Agua de Avena is hands down my absolute, all-time favorite agua fresca. I could drink the stuff every day and never get bored. And I'm not one of those people that likes to eat (or drink) the same thing day after day. But Agua de Avena is so good, I would gladly drink it every day for the rest of my life. Agua de Avena is very similar to Horchata, a traditional Mexican agua fresca made with rice and cinnamon, hence why some people refer to this agua fresca as Horchata de Avena. Agua de Avena is made with oats, cinnamon, and sweetened condensed milk. If you like Horchata, you are going to love Agua de Avena.

Agua de Avena (Oat Horchata) -

Agua de Avena

  • 1 cups old-fashioned oats
  • 10 to 12 cups water
  • 1 cinnamon stick (4-inches)
  • 1 (14 oz.) can sweetened condensed milk
  • Granulated sugar (optional) 

Place the oats in a medium bowl.  Pour in 4 cups of the water and let the oats soak for at least 30 minutes. Puree the oats, the water they were soaked in and a cinnamon stick in a blender until smooth. Strain puree into a 1-gallon pitcher. Add the sweetened condensed milk and stir until completely dissolved. Sweeten with granulated sugar, 1/4 cup at a time, if desired. Serve over ice. Enjoy!

  1. My mom always makes this drink for friends or family after having a baby or breastfeeding.

    She skips the condensed milk and just uses regular milk for me.

    Que rico. I will make some today. Thank you.

  2. Oh yum!!! I love Sweetened condensed milk, now I am just trying to figure out what alcohol would go great in this, lol!

  3. MARCELA: Both my grandfather and my suegra made me pitchers and pitchers of Agua de Avena and Atole de Avena during my Cuarentena! (The 40 days after giving birth!)

    JENNA: I really hope you try this drink. If you're looking to add liquour, RUM is the perfect choice! :)

  4. this one I have not heard of, sounds like it is good for 'new mommies', maybe that is why - but I like the sound of it, now what does that say about grown men....

  5. I was just thinking that some spiced rum would be delicious in this. That sounds sinful!

    I've never had anything like this but I love oatmeal, cinnamon, water and sweetened condensed milk, so what's not to like?

  6. My mother used to make this and drink it in the mornings "para rebajar esos extra kilitos". I don't know if it worked but it tastes delicious!

  9. Hey Leslie, been following your blog for a while. LOVE IT! Never learned how to cook mexican food from my mother(she was too impatient to teach me) but she made most of what you post. Just made the Agua de Avena and it is yummy. I am breastfeeding so hopefully it will boost my MS. :-)

    An aunt of mine came back from Mexico with this recipe jotted down somewhere because her kid fell in love with the drink. She told my mother about it, who then made some and now I'm hooked! We don't add the condensed milk though, I'll have to bring that up later today. :)

  13. I feel like some today. Came back for your recipe ( :

  14. mmm.... just made this and it turned out great!

  15. This was my absolute favorite as a child. I was always so sad to leave my abuelita's house in Mexico because I knew it would be a full year before I got to drink it again!

  16. I love agua de avena! My mom made it all the time when we were kids and now make it for my kids. This recipe is very close to horchata, the agua that my mom made and I now make is very simple. It's just oats, water, cinnamon and sugar. 1 cup oats, 1 1/2 cups sugar, a cinnamon stick all in a gallon container. Add water to top and stir leave in fridge for about an hour then enjoy. My kids like to eat the avena when the agua is finished. It's really simple much healthier then most of the crap we drink and really refreshing. My grand daughter gets excited when she knows I made some.
