Homemade oatmeal shakes are more than just a snack; for families managing Cystic Fibrosis, they are a lifeline. This wonderful option for weight gain is not only nutritious, but it’s also delicious! Even the pickiest children who dislike oatmeal will drink this in one sitting.
When made with a high-calorie base like Kate Farms, these shakes become a powerful tool for boosting caloric intake.
This vegan-friendly recipe is designed to leave your child feeling nourished and full. My son, Anthony, has CF and struggles to maintain his weight. He loves these shakes so much that he asks for them twice a day!
Whether served as a creamy drink, a slushie, or even frozen into homemade ice cream, this “Dominican-inspired” blend is our go-to “bridge” for weight gain.
The Heart Behind the Recipe: From the DR to Our Kitchen

This recipe carries over half a century of family history. My mother taught me how to make this, but its roots go back to her childhood in the Dominican Republic.
Growing up in poverty, my grandmother had six children to feed and often, no milk. She created a simple, satisfying oat-based blend that my grandfather and all the kids loved.
To make it special without expensive ingredients, she added fresh-squeezed orange juice, lime, or vanilla to give the bland oats a boost. This comforting style of drink is known in our culture as “Avena” or a “Batida.”
These Dominican Homemade oatmeal shakes have been a game-changer in our family.
Throughout the years, my mother eventually added dairy to the recipe. However, Anthony’s needs are different. Since he must remain dairy-free, I had to get creative.
Just like Jack Skellington, I started to “ponder and wonder”—how could I bring that traditional comfort to a vegan, high-calorie medical shake?
The result is a blend that combines the soul of my grandmother’s kitchen with the nutritional science Anthony needs today.
Understanding the “Silent Battle” of CF Weight Gain

Cystic Fibrosis is often referred to as a “silent illness.” While a child with CF may look healthy on the outside, their body is engaged in an invisible, high-energy battle every single day.
This leaves many parents, including myself, feeling defeated and isolated.
The problem is due to pancreatic insufficiency. This also means that the sheer metabolic demand of fighting lung infections and breathing through thick mucus is a constant battle.
Children with CF require significantly more calories than their peers to maintain basic growth.
Weight gain is crucial because a higher BMI is directly linked to better lung function; essentially, weight acts as a protective “buffer” for the immune system.
Anthony enjoys his Kate Farms shakes. They are a wonderful, high-quality medical supplement. Although it is a nutrient-dense foundation, some children need an extra caloric “bridge” to meet their intensive daily goals.
This is where my homemade Dominican-inspired homemade oatmeal shakes have become a game-changer.
This shake works by blending the clean protein of a medical shake. It is a process that uses dense, complex carbohydrates of traditional oats and healthy fats.
You can significantly increase the total caloric density in a single sitting, making every sip count toward that vital growth chart progress.
The Current Struggle
Anthony is nearly twelve years old and weighs 56 pounds. It is incredibly difficult to walk into a check-up, see those numbers, and feel like he isn’t getting ahead despite every effort. It makes the doctors’ questions feel so much heavier to carry.
We’ve also hit a hurdle that many people don’t talk about: the intersection of ADHD and Cystic Fibrosis. Lately, we’ve (my mom and I) have been dealing with behavioral challenges where Anthony has been turning off his feeding machine at night.
Finding a full bag of unused formula in the morning is heartbreaking because I know how much that impacts his progress.
This is frustrating and induces more anxiety because, although we explain the importance, Anthony is unfortunately defiant in nature. He gets depressed and does not want his formula.
The teenage years are approaching, and I don’t want him to find new ways to avoid his night feeds.
Long Days lead to Burnout and Stress
I watch him all day after work, and the thought of having to stay up all night just to ensure he gets his feeds is exhausting. We’ve found that using a safe sleep aid like melatonin has been a game-changer, helping him stay asleep so he can get the vital calories he needs overnight.
The Weight of the “Tune-Up“ When those calories are missed, it often leads to a “tune-up”—a hospital stay for intensive IV antibiotics and therapy. For me, these stays are a major anxiety trigger.
Being confined to a hospital room day and night is mentally and physically draining, especially when trying to navigate limited dairy-free meal options for him.
My hope is that these homemade oatmeal shakes provide that extra caloric “safety net”—a delicious way to keep him nourished, healthy, and home with us this summer.

The Recipe: Dominican-Inspired Homemade Oatmeal Shakes

- Prep Time: 5 minutes
- Yields: 1 large shake (approx. 16–20 oz)
Ingredients:
- 1 container (325ml) Kate Farms Peptide 1.5 (Vanilla)
- 1 ½ cups Rolled Oats
- 3 and a half cups of water (divided)
- A pinch of Salt
- 2–3 tbsp Brown Sugar (to taste)
- 1 tsp Vanilla Extract
- Optional: ½ cup orange juice (for traditional flavor) or dairy-free milk (like Califia Farms) for extra creaminess.
- Note: If using cinnamon, ensure it is natural/non-synthetic if your child has sensitivities.
Step-by-Step Instructions:
- Soak: Place the oats and 2 ½ cups of water in your blender. Let them sit for 3–5 minutes to soften.
- First Blend & Strain: Blend on high for one minute. Strain the mixture through a fine-mesh sieve into a large pitcher or a traditional Dominican aluminum mug.
- The “Second Run”: Place the leftover oat pulp back into the blender with the remaining ½ cup of water. Blend again for one minute and strain. This ensures you get every bit of nutrition out of the oats!
- Tip: Add 2 spoonfuls of the strained oats back into the liquid if you prefer a thicker, heartier consistency.
- Boost: Pour the Kate Farms Peptide 1.5 into the oat liquid.
- Flavor: Stir in the vanilla, salt, brown sugar, and optional orange juice.
- Serve: Serve your delicious homemade oatmeal shakes for the kids over ice or chill in the refrigerator.
Parent Reminder: Don’t forget to have your child take their enzymes with this shake!
