Step-by-step overview

Making Rhubarb Crisp with Almond Flour is a delightful journey that combines fresh ingredients into a warm, bubbling dessert. You’ll begin by layering the tart rhubarb mixed with a hint of vanilla, followed by a scrumptious topping that’s nutty and crunchy. In just a few simple steps, your kitchen will be filled with the inviting aroma of baking goodness.

What you’ll need

Here’s everything you’ll need to gather to bring this charming dessert to life:

  • 4 cups rhubarb, chopped
  • 1 cup granulated sugar
  • 1 tablespoon cornstarch
  • 1 teaspoon vanilla extract
  • 1 cup almond flour
  • 1 cup rolled oats
  • 1/2 cup brown sugar
  • 1/2 teaspoon cinnamon
  • 1/4 cup coconut oil or melted butter

Feel free to swap the coconut oil with melted butter if you prefer a richer flavor.

Directions to follow

  1. Preheat your oven to 350°F (175°C). This allows you to jump straight into the baking magic once the mixture is ready.
  2. In a mixing bowl, combine the chopped rhubarb, granulated sugar, cornstarch, and vanilla extract. This combination should create a beautiful, sticky mixture. Spread it evenly in a greased baking dish.
  3. In another bowl, stir together the almond flour, rolled oats, brown sugar, cinnamon, and melted coconut oil or butter until it achieves a crumbly texture. This step is like making a treasure chest; each crumb is a delightful surprise waiting to be uncovered!
  4. Sprinkle the almond flour mixture evenly over the rhubarb in the baking dish, ensuring every bit of fruit has its crunchy companion.
  5. Bake for 30-35 minutes, or until the top turns a luscious golden brown and the rhubarb begins to bubble. The aroma wafting through your kitchen will be irresistible.
  6. Serve warm—I highly recommend pairing it with a scoop of vanilla ice cream. That contrast of hot and cold is simply divine!

Best ways to enjoy it

To truly elevate your Rhubarb Crisp experience, consider plating it with flair. A simple scoop of vanilla ice cream gracefully nestled beside a generous serving of the crisp adds an appealing touch. You can also drizzle a bit of heavy cream over the top for a rich and indulgent finish. For those feeling adventurous, try adding a dash of almond extract to complement the almond flour topping or even serving it with a spoonful of yogurt for a zesty twist.

How to store & freeze

If you find yourself with leftovers (a rare scenario when this crisp is around!), it’s important to store them properly. Let the dish cool completely, then cover it tightly with plastic wrap or transfer it to an airtight container. It can be safely stored in the fridge for about 3-4 days. To enjoy your crisp later, feel free to freeze it before baking. Wrap it tightly and pop it in the freezer; when you’re ready to bake, no need to thaw—just add an additional 5-10 minutes to the baking time.

Helpful cooking tips

  • Choose Fresh Rhubarb: Fresher rhubarb yields the best flavor; look for firm, bright stalks.
  • Adjust the Sweetness: Depending on your taste preferences, feel free to adjust the sugar. Some prefer an extra kick of tartness!
  • Crispier Topping: For even crunchier texture, consider adding crushed nuts or seeds to the topping mixture.

Recipe variations

  • Berries Galore: Mix in blueberries or strawberries alongside the rhubarb for added flavor and sweetness.
  • Spice it Up: Try substituting the cinnamon with nutmeg or allspice for a different aromatic profile.
  • Gluten-Free Option: This recipe naturally accommodates gluten-free diets thanks to almond flour, but you can also use certified gluten-free oats for complete assurance.
