    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 and change them up, removing the dairy and/or replacing it with non-dairy milk. No milk, butter, sour cream, or margarine.

    Substitutions

    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.

    We also grow strawberries in pots and planters. So I've been experimenting with various new strawberry recipes too.

    Right now, I love this rose sangria with fresh sliced strawberries. A refreshing summer evening drink. And my husband has asked me to make these strawberry cheesecake cookies for Father's Day.

    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.

    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!)

    Instructions
     

    • Set oven temp to 350 degrees Fahrenheit.
    • Grease an 8 x 8 cake pan OR line it with parchment paper
    • Combine all the dry ingredients (the first five) in a large mixing bowl.
    • Make a well in the middle.
    • Combine wet ingredients (egg, oatmeal + vinegar, oat milk, and canola oil) in a medium bowl.
    • Pour the wet ingredients into the well in the dry ingredients bowl.
    • Add the strawberries and rhubarb.
    • Mix in the fruit gently, otherwise, you'll end up with pink coffee cake!
    • Stir until just moistened.
    • Pour batter into the cake pan with a spatula.
    • In a small bowl, combine the topping ingredients.
    • Sprinkle topping over the top of the cake batter.
    • Pop it in the oven.
    • After 30 minutes, use a cake tester or knife to ensure the center is set. (I just stick a butter knife in the middle).
    • 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.
