Are you looking for an easy strawberry rhubarb coffee cake recipe without milk? If so, this might be just what you need.
This easy cake recipe uses the perfect combination of strawberries and rhubarb to create a delicious cake for spring and summer.

Recently one of our daughters was diagnosed with a severe intolerance to milk protein. She's also supposed to avoid nuts that come from trees for now.

So for the past twelve weeks, we've been vigilant about checking all the labels on all the food we buy. As always, we're trying to make more of our meals from scratch.

I've been baking at home for a long time, and we have a whole binder full of "family-approved" favorite recipes. Now my task is to go through all of these recipes to change them up and remove the dairy and/or replace the non-dairy milk. No milk, no butter, no sour cream, no margarine.

Depending on the original recipe, I'm replacing dairy ingredients with the following:
- coconut milk
- oatmeal milk
- applesauce
- coconut oil
- canola oil (may try grapeseed oil too)
- crushed flax seeds
- banana

Easy Strawberry Rhubarb Cake Recipe Without Milk
This dairy-free strawberry rhubarb coffee cake recipe evolved with some trial and error. It uses oat milk instead of regular milk.
We're lucky to have fresh rhubarb through the summer months. Our backyard garden includes tart rhubarb plants at each corner.

During rhubarb season (which starts in June here) we harvest rhubarb stalks a couple of times each week. So this time of year we're always on the lookout for rhubarb desserts like strawberry rhubarb pie, strawberry rhubarb jam, and strawberry rhubarb bundt cake.

Since rhubarb can have a bit of a sour taste, many rhubarb recipes call for at least one cup sugar or more. We reduce the sugar because I prefer a less sweet flavor.
Baking with oat milk works well in our recipes because we love that oat flavor. However, oat milk is also denser than the 1% dairy milk I normally use. So I add a little oil to lighten it up.
Dairy-Free Strawberry Rhubarb Coffee Cake Recipe
This easy, moist cake recipe includes sweet strawberries. The sweetness of the strawberries helps reduce the need for sugar. (And by the way, if you love strawberries, check out my Homemade Strawberry Syrup Recipe!)

- ½ cup whole wheat flour
- ¾ cup packed brown sugar
- 1 teaspoon baking soda

- Serve warm, or let the cake cool on a rack
- Enjoy with whipped cream, vanilla ice cream, or just as a simple cake snack!
Notes
Your oil needs to be liquid, so if room temperature oil is solid, warm it in a medium saucepan over medium heat.
Instead of brown sugar, use coconut sugar for a sweetener.
For a tropical variation, add shredded coconut to your cake mix.

We love quickbreads because they're quick to make, they use up leftover fruit, and they're inexpensive.
We often freeze them for later as well. And they're easy to double to triple when we're feeding a crowd. And as a homeschooling family, it's so easy to slice up a coffee cake or loaf for a healthy, fast snack during a busy day.

Rice milk, almond milk & coconut milk all work well sweet in recipes that call for dairy milk, except for instant pudding.
Oat milk works well for both sweet and savory. You can also get by using unsweetened versions of almond or coconut milk. I think rice milk works OK for savory, too… Like mashed potatoes.
Hemp milk is my favorite substitute in creamy casseroles and soups.
I use flax milk in smoothies, for the resistant starch benefit. You can buy it with protein and omegas and it is in the long-life shelf cartons at Natural Grocer. (Ripple is another option, but I pick unsweetened and add my own stevia or xylitol)
Earth balance is dairy free and makes both spread and sticks. They even have a soy-free version. The sticks substitute very well for butter in cooking and baking.
Voilife is a decent cheese substitute. I keep shreds in the freezer and just pull out what I need.
Cashew-based yogurt and kefir are the best taste and consistency in my opinion
I like Toffuti Better Than Sour Cream. (Soy-based)
I haven’t found a cream cheese substitute taste good plain, but the Daiya version goes well with a little jam or to melt some with Earth Balance and alternative milk for
white sauce/Alfredo. You can also meet in some shreds for a cheesier sauce. Play around with combos to find the one you like. You can also melt in some Tofutti BTSC.

Cracky! Your direction mention "oatmeal +vinegar" but your list of ingredients doesn't. Hoping it is just a mistake since it is nearly in the pan.

Oh goodness this looks so good! I love baking with rhubarb and love that you've incorporated it into a coffee cake recipe! Popping in from Lou Lou Girls today 🙂
Joanne
This looks so good! I haven't had rhubarb since I was a kid. We had a neighbor that grew it and allowed us to pick it and eat it (we always dunked it in sugar).
Sarita Harbour
I haven't yet. I planned to, but my gang ate it all in one sitting, lol!
Andrea
Have you tried freezing this? It seems like it should be fine, but it’s nice to not be the guinea pig!
Sarita Harbour
Yup, it's tough trying to find a substitute for cheese....and butter. In baking it's easy to find substitutes - you could make this with coconut milk or almond milk instead of the oat milk. 🙂
Nikki
Oh dear! Dairy free doesn't sound so bad (I don't like milk anyway) until you list cheese, sour cream, butter!!! And.... I've never had rhubarb!
I tried to grow it once, but wasn't real successful, but I want to try again.a

This looks so good! Unfortunately, I have to be gluten-free now, so unless I want to do some serious fiddling (which I might once the weather is kind enough to get below 90F!), I won't be able to taste this one. It looks really good though!

Not much more to say than YUMMMMMM … and always love a healthy recipe
