Moist, tender and packed with jammy bits of sweetly-tart rhubarb, this whole wheat coconut rhubarb breakfast cake is a simple take on a wholesome classic that features chewy coconut for a slightly tropical vibe.
This cake is everything I want in an early summer bake — a simple ingredient list that combines wholesome pantry staples with fragrant vanilla, pops of colour, naturally tart fresh rhubarb and buttery sweet, nutty coconut. Fantastic from the oven still warm, I sometimes think it’s even better reheated with a pat of butter.
Here’s What You’ll Need to Make It
- Whole wheat flour (all-purpose or finely ground)
- Baking powder
- Kosher or fine sea salt
- Rhubarb
- Butter (sub dairy free)
- Sugar
- 1 egg
- Vanilla
- Buttermilk (see note below to make your own)
- Shredded coconut (I’ve used unsweetened but sweetened will work too)
This two-bowl recipe starts with the dry ingredients in one and all the wet ingredients except the buttermilk in another.
Next, the rhubarb is tossed together with the flour mixture in step 2. This helps to soak up any excess moisture and ensures the pieces are evenly distributed and retain their shape.
Then the wet and dry ingredients are combined in stages together with the buttermilk. Lastly, the delicate, shredded coconut is folded in at the end to prevent overmixing.

- The coconut adds a slight chewiness to the texture and provides a lovely, sweet contrast to the rhubarb.
- The batter can be made ahead of time and stored covered in the refrigerator overnight for a quick morning bake.
- Freezer-friendly, you can even slice then stash this cake away in the freezer to enjoy later.
