A light and tender Almond Rhubarb Cake Delight that’s bursting with tangy rhubarb and the nutty richness of almond flour. This beautifully rustic dessert offers a perfect balance of sweet, tart, and buttery richness — ideal for spring and early summer gatherings.

Ingredients

Scale
  • 1 cup almond flour

  • 1/2 cup all-purpose flour (or gluten-free blend)

  • 1/2 teaspoon baking powder

  • 1/4 teaspoon salt

  • 1/2 teaspoon ground cardamom (optional)

  • 1/2 cup unsalted butter, softened

  • 3/4 cup granulated sugar

  • 2 large eggs

  • 1 teaspoon pure vanilla extract

  • 1/4 teaspoon almond extract

  • 1/4 cup sour cream or Greek yogurt

  • 1 1/2 cups chopped rhubarb (fresh or thawed if frozen)

  • 2 tablespoons sliced almonds (for topping)

  • Powdered sugar (for garnish, optional)


Instructions

  1. Preheat oven to 350°F (175°C). Grease and line an 8-inch round cake pan with parchment paper.

  2. Combine dry ingredients: In a medium bowl, whisk together almond flour, all-purpose flour, baking powder, salt, and cardamom.

  3. Cream butter & sugar: In a large bowl, beat butter and sugar until light and fluffy, about 2–3 minutes.

  4. Add eggs & flavorings: Mix in eggs one at a time, then add vanilla, almond extract, and sour cream. Mix until smooth.

  5. Combine wet & dry: Gradually stir in dry ingredients until just combined.

  6. Add rhubarb: Fold in chopped rhubarb gently to distribute evenly throughout the batter.

  7. Pour & top: Transfer the batter into the prepared pan, smoothing the top. Sprinkle with sliced almonds.

  8. Bake for 35–40 minutes or until a toothpick inserted in the center comes out clean.

  9. Cool & serve: Let cake cool in the pan for 10 minutes, then transfer to a wire rack. Dust with powdered sugar before serving if desired.

Notes

  • For an extra tangy flavor, toss rhubarb with 1 tablespoon sugar and let sit 10 minutes before adding to batter.

  • This cake stores well covered at room temperature for up to 2 days, or refrigerated for 4–5 days.

 

  • Substitute chopped strawberries or raspberries for rhubarb when out of season.
