- 1 box yellow cake mix

How to Make Rhubarb Custard Cake: Step-by-Step
Let’s get baking! Here’s how to make this easy rhubarb custard cake:
- Preheat the oven: Preheat your oven to 350°F (175°C).
- Prepare the cake mix: Prepare the yellow cake mix as directed on the box.
- Pour into pan: Pour the batter into a greased 9×13 inch baking pan.
- Add rhubarb and sugar: Sprinkle the chopped rhubarb and granulated sugar evenly over the cake mix batter.
- Pour on the cream: Pour the heavy cream evenly over the rhubarb and sugar. Don’t worry if it seems like a lot of cream; it will bake into a delicious custard.
- Bake: Bake at 350°F (175°C) for 60-70 minutes, or until the cake is golden brown and the custard is set. A toothpick inserted into the center of the cake should come out clean (though the custard layer will still be moist).
- Cool and serve: Let the cake cool slightly before serving. Serve warm, topped with whipped cream or Cool Whip, if desired.
Pro Tips for the Best Rhubarb Custard Cake
Here are a few tips to ensure your rhubarb custard cake turns out perfectly every time:
- Use fresh rhubarb: Fresh rhubarb is always best for this recipe. Look for firm, crisp stalks with a vibrant pink or red color.
- Don’t overbake: Overbaking can result in a dry cake. Keep a close eye on it and remove it from the oven as soon as it’s done.
- Let it cool slightly: Letting the cake cool slightly before serving allows the custard to set up a bit, making it easier to slice and serve.
- Grease your pan well: Be sure to grease your baking pan thoroughly to prevent the cake from sticking. You can also use baking spray with flour.
- Evenly distribute rhubarb: Try to distribute the rhubarb evenly over the cake batter to ensure every bite is packed with flavor.
Common Mistakes to Avoid
Even though this recipe is easy, here are some common mistakes to watch out for:
- Using too much rhubarb: Too much rhubarb can make the cake soggy. Stick to the recommended amount in the recipe.
- Not greasing the pan: Forgetting to grease the pan can cause the cake to stick and be difficult to remove.
- Overmixing the batter: Overmixing the cake batter can result in a tough cake. Mix only until the ingredients are just combined.
- Using old baking powder: Old baking powder can lose its effectiveness, resulting in a flat cake. Make sure your baking powder is fresh.
- Not preheating the oven: Preheating the oven is essential for even baking. Make sure your oven is fully preheated before putting the cake in.
Rhubarb Custard Cake Variations
Want to mix things up? Here are a few fun variations you can try:
- Strawberry Rhubarb: Add sliced strawberries to the rhubarb for a classic and delicious combination.
- Ginger Rhubarb: Add a teaspoon of ground ginger to the cake batter for a warm and spicy twist.
- Almond Rhubarb: Add a teaspoon of almond extract to the cake batter and sprinkle sliced almonds over the top of the cake before baking.
- Lemon Rhubarb: Add the zest of one lemon to the cake batter for a bright and citrusy flavor.
- Spice Cake Rhubarb: Use a spice cake mix instead of yellow cake mix for a richer, more complex flavor.
How to Store Rhubarb Custard Cake
This cake is best stored in the refrigerator. Here’s how to do it:
- Cool completely: Let the cake cool completely before storing.
- Cover tightly: Cover the cake tightly with plastic wrap or store it in an airtight container.
- Refrigerate: Store the cake in the refrigerator for up to 3 days.
To reheat, you can microwave a slice for a few seconds or enjoy it cold straight from the fridge. I think the cake is equally delicious when served cold!
Frequently Asked Questions (FAQ)
Here are some common questions about rhubarb custard cake:
- Can I use frozen rhubarb? Yes, you can use frozen rhubarb. Thaw it completely and drain any excess liquid before using it in the recipe.
- Can I use a different type of cake mix? Yes, you can use a white cake mix or even a butter pecan cake mix.
- Can I use milk instead of heavy cream? While you *can*, the texture won’t be as rich and creamy. Heavy cream really gives the custard its signature texture.
- Can I freeze this cake? I don’t recommend freezing this cake, as the custard may become watery when thawed.
- My cake is browning too quickly, what should I do? Tent the cake with foil. This will deflect some of the heat and slow down the browning process.
Serving Suggestions
Here are some delicious ways to serve your rhubarb custard cake:

- With ice cream: A scoop of vanilla ice cream or rhubarb ripple ice cream is a decadent treat.
- With a dusting of powdered sugar: A simple dusting of powdered sugar adds a touch of elegance.
