Ingredients
- 2 cups rolled oats (200g)
- 1 cup all-purpose flour (120g)
- 3/4 cup granulated sugar (150g)
- 1 tsp baking powder (5g)
- 1/2 tsp baking soda (2.5g)
- 1/4 tsp salt (1.25g)
- 1/2 cup unsalted butter (melted, 115g)
- 2 large eggs
- 1 cup buttermilk (240ml)
- 1 tsp vanilla extract (5ml)
- 2 cups rhubarb (chopped into 1/2-inch pieces, 250g)
- 1/4 cup brown sugar (for topping, 50g)
Method
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This ensures that your cake will bake evenly and rise beautifully.
Step 2: Prepare the Baking Dish
Grease a 9-inch round cake pan or line it with parchment paper to prevent any sticking—nobody wants to lose a slice of this delicious cake!
Step 3: Combine Dry Ingredients
In a large mixing bowl, whisk together the rolled oats, all-purpose flour, granulated sugar, baking powder, baking soda, and salt. This blend of ingredients creates the base for our cake.
Step 4: Mix Wet Ingredients
In another bowl, beat the melted butter, eggs, buttermilk, and vanilla extract until well combined. The melted butter adds richness, while the buttermilk gives the cake its moistness.
Step 5: Blend Dry and Wet Mixtures
Gently fold the wet mixture into the dry ingredients until just combined. Be careful not to overmix; a few lumps are perfectly fine.
Step 6: Incorporate Rhubarb
Add the chopped rhubarb to the batter and fold it in gently, ensuring it’s evenly distributed throughout the mixture.
Step 7: Transfer to Baking Dish
Pour the batter into the prepared cake pan, spreading it out evenly.
Step 8: Create Topping
Sprinkle the brown sugar over the top of the batter. This will create a delightful caramelized crust as it bakes.
Step 9: Bake the Cake
Place the cake in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. The aroma will be irresistible!
Step 10: Cool the Cake
Once baked, remove the cake from the oven and allow it to cool in the pan for about 10 minutes. Then transfer it to a wire rack to cool completely.
Serving Suggestions & Pairings
This Oat Icelandic Rhubarb Cake enjoys a place at any table. Serve it warm, dusted with a sprinkle of powdered sugar, or alongside a scoop of vanilla ice cream for a dessert that sings of spring. Pair it with a cup of herbal tea or a sophisticated espresso for an afternoon pick-me-up.
Storage & Leftovers Guide
If you have any cake left (which I doubt!), store it in an airtight container at room temperature for up to three days. If you’d like to keep it longer, wrap it tightly and freeze for up to three months. Just thaw in the fridge overnight when you’re ready to enjoy it again!
Kitchen Wisdom & Success Tips
- Choosing Rhubarb: Look for firm stalks that are vibrant in color for the best flavor.
- Cutting Rhubarb: Ensure you chop the rhubarb into even pieces to allow for consistent cooking.
- Don’t Overmix: Gently folding is key to maintaining the cake’s light texture.
- Extra Flavor: Feel free to add cinnamon or nutmeg to the batter for an extra spice kick.
- Serving Warm: This cake is best served slightly warm, enhancing its comforting texture.
Flavor Variations & Adaptations
If rhubarb isn’t your thing, consider substituting with strawberries or apples for a different twist. You can also add nuts like walnuts or pecans for an extra layer of texture.
Reader Questions & Solutions
- Can I use gluten-free flour? Yes! Just substitute all-purpose flour with a gluten-free blend.
- What if I don’t have buttermilk? You can make a quick substitute by adding a tablespoon of vinegar or lemon juice to a cup of milk and letting it sit for 10 minutes.
- Can I add more sugar? Absolutely! If you prefer a sweeter cake, feel free to increase the sugar, but remember the rhubarb brings some natural tartness.
- Is it okay to use frozen rhubarb? Yes, just make sure to thaw and drain excess moisture before adding it to the batter.
- How do I know when it’s done? A toothpick inserted in the center should come out clean, with a few moist crumbs but no wet batter.
