How to Make Rhubarb Cake
-
Preheat the oven: Set your oven to 350°F (175°C) and prepare a baking pan by spraying it generously with cooking spray to prevent sticking.
-
Combine dry ingredients: In a large mixing bowl, whisk together the all-purpose flour, almond flour, baking powder, baking soda, and kosher salt. Set this mixture aside for later use.
-
Cream butter and sugars: In another bowl, cream the softened butter with the granulated and light brown sugars until the mixture is light and fluffy—this should take about 3-5 minutes for the perfect texture.
-
Incorporate eggs and extracts: Add the eggs one at a time, mixing well after each addition. Then, blend in the vanilla and almond extracts to enhance the flavor medley.
-
Mix wet and dry ingredients: Gradually add the dry ingredient mixture to the wet ingredients, alternating with buttermilk. Stir until just combined—no need to overmix!
-
Fold in rhubarb: Gently fold in the sliced rhubarb pieces until evenly distributed throughout the batter. Pour the mixture into your prepared baking pan, smoothing the top.
-
Add sugar topping: Sprinkle a generous layer of granulated sugar on top of the batter before placing it in the oven—this crispy coating will be divine!
-
Bake the cake: Place the pan in the oven and bake for approximately 1 hour, or until the cake is set and golden brown. A toothpick inserted into the center should come out clean.
-
Cool and serve: Allow the cake to cool in the pan for about 10-15 minutes before transferring it to a wire rack to cool completely.
Optional: Serve with a dollop of homemade whipped cream or a scoop of vanilla ice cream for a lovely finish.

-
Sugar Topping: Don’t skimp on the sugar topping—it creates a delightful crispy layer that enhances flavor and texture.

Baking Time: Keep an eye on the baking time; start checking for doneness at 50 minutes to prevent overbaking, which can dry out the cake.

Rhubarb Cake Recipe FAQs
How do I choose the right rhubarb?
Absolutely! Look for rhubarb stalks that are firm, crisp, and free from dark spots or wilting. The best rhubarb is vibrant in color—typically a mix of pink and green—and the stalks should feel heavy in your hand. Don’t hesitate to trim the ends for a cleaner look before using them in your cake!
How should I store the leftover Rhubarb Cake?
You can store your leftover Rhubarb Cake in an airtight container at room temperature for about 3-4 days. If you live in a particularly warm climate, refrigeration is a better option—just remember to cover it well. It can last up to a week in the fridge, maintaining that delicious flavor.
Can I freeze my Rhubarb Cake?
Very much! To freeze your Rhubarb Cake, cut it into individual slices and wrap each slice tightly in plastic wrap. Then, wrap it in aluminum foil in order to prevent freezer burn. Place the wrapped slices in a freezer-safe bag. They can stay frozen for up to 3 months. When you’re ready to enjoy, simply thaw in the fridge overnight, then warm in the oven to restore that fresh-baked taste!
What should I do if my cake is too dense?
If your Rhubarb Cake turned out dense, it might be due to overmixing the batter. Remember, when combining wet and dry ingredients, mix just until incorporated. Additionally, ensure your baking powder and baking soda are fresh; stale leavening agents can affect the cake’s rise. To avoid this in the future, embrace the folding technique when adding in your ingredients.
Are there any dietary considerations I should keep in mind?
Absolutely! This Rhubarb Cake can be easily customized. You can use vegan butter instead of regular butter for a dairy-free version or substitute with coconut flour instead of almond flour for gluten-free needs—just remember to adjust liquid quantities accordingly. If you have allergies, make sure to check for any specific ingredients that might not fit into your dietary guidelines.
What can I serve with my Rhubarb Cake?
This delightful cake pairs beautifully with homemade whipped cream or a scoop of vanilla ice cream for that ultimate sweet-tart balance. I often drizzle a light glaze made from powdered sugar and lemon juice on top for an added zing and a stunning finish; it’s truly a crowd-pleaser!
