Essential Ingredients
Here’s what you’ll need to make this delicious dish:
Fresh Rhubarb: Look for vibrant stalks without blemishes; they should be firm yet tender.
Blueberries: Opt for plump, juicy berries; frozen ones work too if fresh isn’t available.
Rolled Oats: Choose whole rolled oats for texture; they bind beautifully in the cake.
Almond Flour: This adds moisture and nutty flavor; ensure it’s finely ground for best results.
Sugar: Use granulated sugar to balance the tartness; adjust sweetness based on your taste preference.
Baking Powder: Essential for leavening; check freshness to ensure your cake rises perfectly.
Eggs: Large eggs help bind the mixture together; room temperature works best here.
Buttermilk: Adds richness and tanginess; if unavailable, mix milk with lemon juice as a substitute.
Vanilla Extract: A splash elevates flavors; opt for pure vanilla for a deeper taste.
Salt: Just a pinch enhances all the flavors without making it salty.

How to Make Rhubarb Blueberry Oat and Almond Cake
Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9-inch round cake pan with butter or cooking spray to prevent sticking.
Prepare Fruits: Chop rhubarb into small pieces and toss them in a bowl with blueberries. This mixture enhances their natural sweetness when baked.
Mix Dry Ingredients: In another bowl, combine rolled oats, almond flour, baking powder, and salt. Whisk together until well blended to avoid clumps in your batter.
Cream Sugar & Eggs: In a mixing bowl, cream together sugar and eggs until light and fluffy. This step aerates the mixture, giving your cake that delightful rise.
Combine Wet Ingredients: Add buttermilk and vanilla extract to the egg mixture. Stir gently until combined but be careful not to over-mix.
Fold in Dry Ingredients: Gradually fold the dry mixture into the wet ingredients using a spatula. Be gentle to keep air bubbles intact for a fluffy texture.
Add Fruit & Bake: Gently fold in chopped rhubarb and blueberries until evenly distributed throughout the batter. Pour into your prepared pan and bake for 35-40 minutes or until golden brown.
Cool & Serve: Allow the cake to cool in the pan for about 10 minutes before transferring it to a wire rack. Serve warm or at room temperature—perfect with coffee or tea!
