Preparation
- Step 1
Heat oven to 350 degrees.
- Step 2
Make the filling: In a large bowl, toss together rhubarb, sugar, tapioca or cornstarch, vanilla and, if using, zest. Pour into a 2-quart baking dish or 9-inch round or square baking pan. Put the dish on top of a baking sheet to catch any drips.
- Step 3
Next, make the topping: Add the almond butter to the same bowl you used for the rhubarb (no need to wash it). Stir with a flexible spatula to eliminate any lumps if needed, then mix in almond flour, coconut, sugar and salt. (Or, add all the ingredients to a food processor and pulse to incorporate, 12 to 15 times, until no dry spots remain.) If the mixture seems dry, add more almond butter by the teaspoon until it clumps together when pressed between your fingers. Sprinkle evenly over the rhubarb.
- Step 4
Bake until the topping is golden and the filling is bubbling around the edges, 35 to 40 minutes. Let cool for at least 20 minutes before serving. Serve warm or at room temperature.

If you're never used rhubarb, wouldn't this recipe be a great introduction?
From her article: You can substitute other fruit, so long as you adjust the sugar content. For sweet cherries, berries and stone fruit, use about half as much sugar called for. For sour cherries, keep the sugar where it is. Frozen fruit (rhubarb, berries or otherwise) works well here, too, and doesn’t have to be thawed first; just add a few minutes to the baking time. Frozen blueberries, preferably zipped up with the juice and zest of a lemon, will turn this dessert from rosy and tangy to inky
I’ve been growing and eating rhubarb for many decades. For anyone unfamiliar with cooking with it, the raw stalks can be red or green. Once cooked, they fade to a pinkish tan. It will never look as red as the picture that accompanies this recipe. (without an adding a few drops of red food coloring). Don’t let the lack of bright color deter you. The taste is phenomenal!
We weren't fans of the almond butter, almond flour, coconut topping. A little mushy and cloying. We have a lovely rhubarb patch and are always looking for interesting recipes to try with it. I'm glad we gave this one a go, even if we won't be making it again.
It's been at least 10 years since I've seen rhubarb in Los Angeles. I used a combo of strawberries and apple for the fruit and just a tablespoon of sugar. The topping was very wet the first time, & didn't crisp up at all during cooking. Second time, I used 3 oz gf flour, 1 T sugar, 60g nut flour, 60g coconut, 180g nut butter, 1 beaten egg, and 3/4 cup of rolled oats. Worked so much better - crumbly but not dry, and delicious. Both times, the fruit needed 1 hour to cook.
Unfortunately this was a miss for me. It ended up being much too sweet and I didn’t enjoy the rhubarb - almond butter flavour combination. ended up tossing the whole thing, huge waste.
