Importance of Each Tool

Ingredients
Dairy & Eggs
- 1/2 cup half and half, cream, or buttermilk
- 1 tsp lemon juice
- 1/2 cup unsalted butter at room temperature
- 1 large egg, at room temperature
Sugar & Flavorings
- 1 cup granulated sugar plus 2 tsp for sprinkling
- 1 1/2 tsp vanilla extract
Dry Ingredients
- 2 cups all purpose flour, saving out 1 Tbsp to toss with rhubarb
- 2 tsp baking powder
- 1 tsp salt
Fruit
- 2 cups thinly sliced rhubarb
How to Make Rhubarb Cake
Step 1: Preheat the Oven
Preheat the oven to 350°F. Lightly butter a 9×9 square baking pan. If desired, line the pan with parchment paper so that it hangs over the sides for easy removal later.
Step 2: Prepare Buttermilk Mixture
Stir the lemon juice into the half and half and set aside. This will create a slight tanginess in your cake.
Step 3: Cream Butter and Sugar
Cream the soft butter and sugar in a stand mixer or with electric beaters until fluffy and pale yellow. Beat in the egg and vanilla extract while scraping down the bowl as necessary.
Step 4: Toss Rhubarb in Flour
Take 1 tablespoon of flour from your measured amount and toss it with the sliced rhubarb. This helps prevent the rhubarb from sinking to the bottom during baking.
Step 5: Combine Dry Ingredients
In a separate bowl, whisk together the remaining flour, baking powder, and salt until combined.
Step 6: Mix Batter
Add half of the flour mixture to the bowl with creamed butter. Blend in gently. Then add all of the half and half mixture and blend again. Finally, add in the rest of the flour mixture just until combined—do not over mix! Carefully fold in the floured rhubarb pieces.
Step 7: Bake
Spread the batter evenly into your prepared pan. Sprinkle a little sugar on top for added sweetness. Bake for about 40-45 minutes or until golden brown. A toothpick inserted into the center should come out clean (moist crumbs are fine).
Step 8: Cool Before Cutting
Allow your cake to cool slightly before cutting into squares to serve. Enjoy!

For Breakfast

How to Perfect Rhubarb Cake
To ensure your Rhubarb Cake turns out perfectly every time, follow these simple tips:
- Use fresh rhubarb: Fresh rhubarb provides the best flavor and texture. Avoid using frozen rhubarb as it may make the cake soggy.
- Measure ingredients accurately: Precision in measuring flour and sugar can greatly impact the cake’s texture. Use a kitchen scale if possible.
- Don’t overmix: Mix just until combined to keep the cake tender and fluffy. Overmixing can lead to a dense texture.
- Check doneness carefully: Use a toothpick to test for doneness; moist crumbs are okay, but wet batter indicates it needs more time.
- Cool before slicing: Let the cake cool slightly before cutting it into pieces. This helps maintain its structure and prevents crumbling.
- Store properly: Keep any leftovers in an airtight container at room temperature for up to three days or refrigerate for longer freshness.
Best Side Dishes for Rhubarb Cake
Rhubarb Cake pairs well with various side dishes that complement its unique flavor profile. Here are some great options:
- Fresh Fruit Salad: A mix of seasonal fruits adds brightness and balances the tartness of the cake.
- Scrambled Eggs: Fluffy scrambled eggs provide protein that makes this dish suitable for breakfast.
- Greek Yogurt Parfait: Layer Greek yogurt with granola and fruit for a healthy side that contrasts nicely with the cake’s sweetness.
- Cheese Platter: Offer assorted cheeses like brie or goat cheese alongside crackers for a savory touch.
- Coffee or Tea: A cup of hot coffee or herbal tea enhances your enjoyment while providing warmth on cooler days.
- Honey Butter Spread: A spread of honey butter adds sweetness that pairs beautifully with each slice of cake.
- Roasted Nuts: Crunchy roasted nuts add texture and health benefits, making them an excellent snack alongside your cake.
- Vanilla Ice Cream: A scoop of vanilla ice cream serves as a creamy contrast to the tartness of the rhubarb in the cake.
Common Mistakes to Avoid
Baking the perfect Rhubarb Cake can be tricky, but avoiding common mistakes makes it easier. Here are some pitfalls to watch out for:
-
Using cold ingredients: Always ensure that your butter and eggs are at room temperature. Cold ingredients can lead to a dense cake texture that doesn’t rise properly.
-
Overmixing the batter: When combining the flour mixture with the wet ingredients, mix just until combined. Overmixing can toughen the cake and affect its fluffiness.
-
Not prepping the rhubarb correctly: Tossing the rhubarb in flour helps prevent it from sinking to the bottom of the cake. Skipping this step may result in uneven distribution.
-
Ignoring baking times: Every oven is different, so keep an eye on your cake as it bakes. Check for doneness a few minutes before the suggested time to avoid overbaking.
-
Neglecting to line your pan: While optional, lining your baking pan with parchment paper makes removing the cake much easier. This prevents it from sticking and breaking apart during transfer.
Storage & Reheating Instructions
Refrigerator Storage
