Warm Rhubarb Cake Ingredients
This cake is simple yet delightful, featuring rhubarb as its star ingredient.
For the Cake
- All-purpose flour – Provides structure; substitute with a gluten-free flour blend for a gluten-free option.
- Granulated sugar – Adds sweetness; for a deeper flavor, you can use brown sugar instead.
- Baking powder – A leavening agent; ensure it’s fresh for the best rise in your cake.
- Salt – Enhances flavor; using kosher or sea salt brings out the cake’s sweetness.
- Fresh or frozen rhubarb – The primary flavor component; fresh should be firm and pink, while frozen needs thawing and draining for moisture management.
- Milk – Adds moisture and richness; non-dairy milk can be a great substitute for a dairy-free version.
- Butter – Contributes richness and flavor; use unsalted butter, or replace it with non-dairy margarine if preferred.
For the Butter Sauce
- Butter – Gives the sauce a rich, velvety texture; unsalted is best for controlling saltiness.
- Granulated sugar – Sweetens the sauce; it also helps create that luscious glaze when heated.
- Heavy cream – Provides a creamy base; for a lighter option, half-and-half works well.

Warm Rhubarb Cake with Butter Sauce Recipe FAQs
How do I choose the best rhubarb?
When selecting fresh rhubarb, look for firm stalks that are bright pink in color; avoid any that show dark spots or wilting. If you’re using frozen rhubarb, ensure it has been completely thawed and drained to manage moisture, as excess liquid can result in a soggy cake.
How should I store the warm rhubarb cake?
To preserve the cake’s moisture, store it in an airtight container at room temperature for up to 2 days. If you plan to keep it longer, refrigerate it for up to 5 days, making sure it cools completely before covering to maintain freshness.
Can I freeze the warm rhubarb cake?
Absolutely! You can freeze the cake (without the butter sauce) for up to 3 months. To do this, wrap it tightly in plastic wrap and then in foil to avoid freezer burn. When ready to enjoy, thaw overnight in the fridge and reheat in the oven at 350°F (175°C) for about 10 minutes.
What if my butter sauce turns grainy?
If your butter sauce ends up grainy, it might be due to cooking at too high of heat or not whisking enough. To avoid this, cook over medium-low heat and whisk continuously as you add the cream. If it still becomes grainy, try straining it to achieve a smoother texture.
Can I use substitutes in the recipe for dietary needs?
Certainly! For gluten-free needs, substitute all-purpose flour with a gluten-free blend. If you need a dairy-free option, you can use non-dairy milk and margarine instead of butter. Make sure that the margarine is also non-hydrogenated for the best results.
Is this recipe safe for pets?
While rhubarb is safe for human consumption, it is not safe for pets, especially for dogs and cats. The leaves and unripe stalks can be toxic. If your pet is prone to looking for food scraps, make sure to keep the cake out of their reach.
