This strawberry rhubarb cake is a perfect balance of tart and sweet with a luscious honey glaze that ties it all together. The fresh fruit keeps it light and bright—ideal for spring or summer gatherings!
Introduction
I first made this strawberry rhubarb cake a few springs ago when rhubarb was just popping up at the farmer’s market. I was looking for a way to showcase the tartness of rhubarb alongside the natural sweetness of fresh strawberries. This cake quickly became a favorite in my family because it’s not overly sweet and has this lovely honey glaze that adds a subtle floral note. What sets this version apart is using sour cream in the batter, which keeps the crumb moist and tender without weighing it down. Also, folding in the fruit gently prevents it from sinking to the bottom, so every bite has a balanced burst of flavor. The honey glaze is a simple but magical touch — it soaks in just enough to keep the cake moist and adds a delicate shine. When it comes out of the oven, it’s soft, fragrant, and perfect for a spring dessert or a weekend treat with coffee. I love how the colors pop and the fresh fruit makes it feel light, even though it’s rich and satisfying. Honestly, I had a few failed attempts at sinking fruit before I learned the trick of coating the rhubarb in a bit of flour and folding carefully — that was a game changer. If you’re a fan of fresh fruit desserts that aren’t too sweet, this cake will definitely become a go-to.
What You'll Need
One 9-inch round cake, 8 servings
- 1 1/2 cups all-purpose flour, sifted
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup unsalted butter, softened
- 3/4 cup granulated sugar
- 2 large eggs, room temperature
- 1 teaspoon vanilla extract
- 1/2 cup sour cream
- 1 cup fresh strawberries, hulled and quartered
- 1 cup fresh rhubarb, chopped into 1/2 inch pieces
- 1/4 cup honey
- 2 tablespoons water
- 1 teaspoon lemon juice
How To Do It
Step 1
Preheat your oven to 350°F (175°C) and grease a 9-inch round cake pan, then line it with parchment paper. This ensures the cake releases easily after baking. It’s important to prepare the pan well so the delicate crumb doesn’t stick or break when you remove it.
⏱ Time: 10 minutes
✓ Doneness: Pan is evenly greased and parchment paper fits snugly without wrinkles
Step 2
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Mixing the dry ingredients separately helps distribute the leavening agents evenly throughout the batter, which is key for a uniform rise.
⏱ Time: 5 minutes
✓ Doneness: Dry ingredients are fully combined with no clumps
Step 3
In a large bowl, beat the softened butter and sugar together until light and fluffy, about 3-4 minutes. This step incorporates air into the batter, which helps create a tender and airy texture in the final cake.
⏱ Time: 4 minutes
✓ Doneness: Mixture is pale in color and has a fluffy texture
Step 4
Add the eggs one at a time, beating well after each addition. Then mix in the vanilla extract. Adding eggs slowly ensures they emulsify properly with the butter and sugar, preventing a curdled batter and promoting a smooth texture.
⏱ Time: 3 minutes
✓ Doneness: Batter looks smooth and glossy without streaks
Step 5
Alternately add the dry ingredients and sour cream to the wet mixture, starting and ending with the dry ingredients. Mix gently after each addition just until combined. Overmixing can develop gluten and make the cake tough, so be careful to fold lightly.
⏱ Time: 5 minutes
✓ Doneness: Batter is smooth and slightly thick, no visible flour streaks
Step 6
Toss the chopped rhubarb and strawberries with a tablespoon of flour to coat. This prevents the fruit from sinking to the bottom during baking and helps distribute it evenly throughout the cake.
⏱ Time: 3 minutes
✓ Doneness: Fruit pieces are evenly coated with flour and separated
Step 7
Gently fold the coated fruit into the batter, being careful not to overmix. This keeps the fruit intact and prevents the batter from deflating, ensuring a nice crumb and even fruit distribution.
⏱ Time: 2 minutes
✓ Doneness: Fruit is evenly dispersed without clumps or streaks
Step 8
Pour the batter into the prepared pan and smooth the top with a spatula. Bake in the preheated oven for 35-40 minutes, or until a toothpick inserted in the center comes out clean. Baking time can vary depending on your oven, so start checking at 35 minutes to avoid overbaking.
⏱ Time: 35-40 minutes
✓ Doneness: Cake surface is golden brown and toothpick comes out clean
Step 9
While the cake is baking, combine honey, water, and lemon juice in a small saucepan and warm gently until just runny. Once the cake is out of the oven and still warm, brush the honey glaze over the top. This adds moisture and a beautiful shine, plus a subtle sweet floral flavor that complements the fruit perfectly.
⏱ Time: 5 minutes
✓ Doneness: Glaze is warm and liquid, coats the cake evenly without pooling
Pro Tips
Don’t skip sifting the dry ingredients.
Sifting aerates the flour and evenly distributes the baking powder and soda, which helps the cake rise uniformly and prevents dense spots.
Use room temperature eggs and butter.
Room temperature ingredients blend more smoothly, trapping air better during creaming, which results in a lighter, fluffier cake.
Fold the fruit in gently and last.
This prevents the batter from deflating and keeps the fruit pieces intact, ensuring even distribution and a tender crumb.
Brush the honey glaze while the cake is still warm.
Warm cake absorbs the glaze better, locking in moisture and adding a shiny, flavorful finish.
Use a toothpick to check doneness starting at 35 minutes.
Ovens vary, and overbaking dries out the cake. A clean toothpick means the cake is perfectly baked and moist.
Coat the fruit with flour before folding in.
This prevents the fruit from sinking and keeps the batter from becoming too wet in spots, maintaining an even texture.
Let the cake cool in the pan for 10 minutes before removing.
This helps the cake set and reduces the risk of it breaking apart when unmolding.
Common Mistakes to Avoid
Overmixing the batter
Why it happens It’s easy to want to mix until perfectly smooth, but overmixing develops gluten and makes the cake tough.
Fix Mix just until the ingredients are combined and no dry streaks remain. Use gentle folding motions especially after adding flour.
Using underripe or watery fruit
Why it happens Sometimes fruit looks fine but is too soft or watery, which can make the cake soggy.
Fix Choose firm, ripe strawberries and fresh rhubarb. Toss fruit with flour to absorb excess moisture.
Not preparing the pan properly
Why it happens Skipping greasing or parchment lining can cause sticking and breakage.
Fix Always grease and line your pan with parchment paper to ensure easy release.
Applying glaze when cake is cold
Why it happens Cold cake won’t absorb the glaze, leaving it sticky and uneven.
Fix Brush the honey glaze on while the cake is warm for best absorption and shine.
Baking at too high a temperature
Why it happens A hotter oven can cause the cake edges to brown too fast while the center remains undercooked.
Fix Bake at 350°F and check for doneness early with a toothpick.
Variations
Almond Rhubarb Strawberry Cake
Add 1/2 teaspoon almond extract to the batter and sprinkle sliced almonds on top before baking. This adds a nutty aroma and crunchy texture that pairs beautifully with the fruit.
Note: Almond extract is potent, so use sparingly. The nuts toast during baking, enhancing flavor without extra steps.
Gluten-Free Version
Swap all-purpose flour for a gluten-free blend that includes xanthan gum. This keeps the cake tender and moist without gluten, perfect for sensitive diets.
Note: Gluten-free flours absorb liquid differently; you may need to adjust sour cream slightly for batter consistency.
Vegan Adaptation
Use flax eggs (1 tbsp flaxseed meal + 3 tbsp water per egg), vegan butter, and coconut yogurt instead of sour cream. The honey can be replaced with maple syrup for a fully vegan glaze.
Note: Vegan batters may be denser; fold fruit gently and bake a bit longer, checking doneness carefully.
Spiced Strawberry Rhubarb Cake
Add 1/2 teaspoon ground cinnamon and 1/4 teaspoon ground ginger to the dry ingredients for a warm, cozy flavor twist that complements the tart fruit.
Note: Spices can intensify during baking; start with small amounts and adjust to taste.
Lemon Zest Honey Glaze
Add 1 teaspoon finely grated lemon zest to the honey glaze for a bright citrus note that cuts through the sweetness and adds freshness.
Note: Zest should be finely grated to avoid bitter pith and blend smoothly into the glaze.

Storage & Tips
Room Temperature
Store the cake covered loosely with a cake dome or plastic wrap at room temperature for up to 2 days. This keeps it moist but avoid leaving it uncovered as it will dry out quickly.
Refrigerator
Keep the cake in an airtight container in the fridge for up to 5 days. The honey glaze may firm up and the cake will be denser when cold, so let it come to room temperature before serving or warm slightly.
Freezer
Wrap the cooled cake tightly in plastic wrap and then foil, freeze for up to 3 months. Thaw overnight in the fridge, then bring to room temperature before serving to restore texture.
Reheating
Warm slices gently in a microwave for 15-20 seconds or in a 300°F oven for 5-7 minutes. Avoid overheating as it can dry out the cake. Add a splash of water or honey if reheating in the oven to keep moist.
Make Ahead
You can prepare the batter and fold in the fruit up to 1 day ahead, storing it covered in the fridge. Bake fresh the next day for best texture and flavor. The honey glaze is best applied right after baking.
FAQ
Can I use frozen strawberries and rhubarb for this cake?
You can, but frozen fruit releases more moisture, which may make the cake soggy. If using frozen, thaw and drain excess liquid well, then toss with flour before folding into the batter to help absorb moisture.
Why is my cake dense and not rising well?
This usually happens if the leavening agents are old or if the batter was overmixed. Make sure your baking powder and soda are fresh and mix the batter gently to keep it airy.
Can I substitute honey with maple syrup for the glaze?
Yes, maple syrup works well as a glaze alternative and adds a nice flavor. Warm it gently with lemon juice and water just like the honey glaze for easy application.
What’s the best way to store leftover cake?
Store leftovers in an airtight container at room temperature for up to 2 days or in the fridge for up to 5 days. Bring to room temperature or warm slightly before eating for best texture.
How do I prevent the fruit from sinking to the bottom?
Coating the fruit in a tablespoon of flour before folding it into the batter helps suspend it evenly. Also, fold gently to avoid deflating the batter.
Can I make this cake dairy-free?
Yes, substitute sour cream with coconut yogurt or a dairy-free yogurt and butter with vegan butter. The texture might be slightly different but still delicious.
Is it okay to use frozen rhubarb in this recipe?
Frozen rhubarb works if properly thawed and drained. Excess moisture can affect texture, so toss with flour before adding to batter to minimize sogginess.
How do I know when the cake is done?
Insert a toothpick in the center; if it comes out clean or with a few moist crumbs, the cake is done. The top should be golden brown and spring back lightly when touched.
