Bake With the Seasons · February

February sits in an interesting place in the baking year. Winter is still very much here, but the first brighter flavors begin nudging their way onto the table. In fact, this strawberry-rhubarb crumb cake tastes like that exact moment.

A soft Greek-yogurt cake holds pockets of strawberries and tart rhubarb beneath a generous, irregular layer of buttery brown-sugar crumbs. Meanwhile, the berries become jammy in the oven, while the rhubarb keeps all that sweetness from becoming too polite.

It’s part breakfast cake, part coffee cake, and part fruit crumble—and there is absolutely no reason to force it to choose.

Why You’ll Love This Strawberry-Rhubarb Crumb Cake

• Sweet strawberries and tart rhubarb balance each other naturally
• Greek yogurt keeps the cake tender
• A generous brown-sugar crumble gives it crisp, buttery texture
• No frosting or decorating required
• Fresh or frozen rhubarb can work
• Just as welcome at brunch as it is for dessert

A Note About Strawberry and Rhubarb Season

Strawberries and rhubarb don’t arrive at exactly the same time everywhere. In warmer regions, early strawberries may begin appearing while much of the country is still firmly in winter. Meanwhile, rhubarb may be available from forced production, markets, grocery stores, or the freezer before local garden rhubarb wakes up.

So think of this February cake as an early-season bake rather than a promise that both fruits are growing locally everywhere right now. If your local season hasn’t begun yet, frozen fruit lets you bake it now—or save the recipe for the first real stalks and berries of spring.

Ingredients

For the Crumb Topping

• 3/4 cup all-purpose flour
• 1/3 cup packed light brown sugar
• 2 tablespoons granulated sugar
• 1/2 teaspoon ground cinnamon
• Pinch of fine salt
• 5 tablespoons unsalted butter, melted

For the Strawberry-Rhubarb Filling

• 1 cup strawberries, hulled and chopped
• 1 cup rhubarb, cut into roughly 1/2-inch pieces
• 2 tablespoons granulated sugar
• 1 tablespoon cornstarch
• 1 teaspoon fresh lemon juice

For the Cake

• 1 1/2 cups all-purpose flour
• 1 1/2 teaspoons baking powder
• 1/4 teaspoon baking soda
• 1/2 teaspoon fine salt
• 1/2 cup unsalted butter, softened
• 2/3 cup granulated sugar
• 2 large eggs
• 1 teaspoon vanilla extract
• 1/2 cup plain Greek yogurt or sour cream
• 2 tablespoons milk

How to Make Strawberry-Rhubarb Crumb Cake

1. Prepare the Pan

Preheat the oven to 350°F (175°C). Grease an 8-inch square baking pan and line it with parchment paper, leaving enough overhang to lift the cooled cake out.

2. Make the Crumb Topping

Stir together the flour, brown sugar, granulated sugar, cinnamon, and salt. Pour in the melted butter and mix with a fork until uneven crumbs form.

Don’t pulverize them into uniform sand. Instead, leave some little crumbs alongside larger buttery clumps. Once the texture looks irregular, set the mixture aside while you make the cake.

3. Prepare the Fruit

Combine the strawberries, rhubarb, sugar, cornstarch, and lemon juice in a bowl. Toss gently until the fruit is coated, then set it aside briefly.

4. Mix the Dry Ingredients

Meanwhile, whisk the flour, baking powder, baking soda, and salt together in a separate bowl.

5. Make the Cake Batter

Beat the softened butter and sugar until creamy and slightly lighter. Add the eggs one at a time, followed by the vanilla.

Next, mix in the Greek yogurt. Fold in the dry ingredients, adding the milk as needed, just until the batter is thick and combined.

6. Assemble the Cake

Spread the batter evenly in the prepared pan. Scatter the strawberry-rhubarb mixture over the top, including the fruit but leaving behind any large puddle of liquid that has collected in the bowl.

Finally, crumble the topping over the fruit with your fingers. Let some pieces stay larger than others rather than covering the cake with a perfectly even layer.

7. Bake

Bake for approximately 45–55 minutes, until the crumb topping is golden, the fruit is bubbling in places, and a tester inserted into a cake-heavy section comes out clean or with a few moist crumbs.

Because there is juicy fruit on top, avoid testing directly through a strawberry pocket and assuming the cake is raw.

8. Cool Before Cutting

Let the cake cool in the pan for at least 30 minutes. The fruit layer thickens as it cools, so cutting immediately can turn a perfectly good crumb cake into a delicious landslide.

Why Strawberry and Rhubarb Work Together

Rhubarb is assertively tart, while ripe strawberries bring sweetness and perfume. Put them together and each fixes the other’s excess: strawberries soften rhubarb’s sharpness, and rhubarb keeps cooked strawberries from becoming one-note sweet.

Brown sugar and butter then add a deeper flavor on top, making the fruit taste even brighter by contrast.

Can I Use Frozen Rhubarb?

Yes. Frozen rhubarb makes this recipe much more practical when fresh stalks aren’t available yet. For best results, use it directly from frozen rather than thawing it completely first; the cake may need a few additional minutes in the oven.

If the frozen rhubarb is coated in a lot of loose ice crystals, brush those away before measuring.

Can I Use Frozen Strawberries?

Fresh strawberries are preferable because frozen berries release more water and soften dramatically as they bake. However, frozen strawberries can still work in a pinch.

Keep them frozen, cut very large berries into smaller pieces if possible, and add an extra teaspoon of cornstarch to the fruit mixture. As a result, the finished layer may be softer and more jammy, but it will still taste wonderful.

How to Keep Fruit Crumb Cake From Getting Soggy

• Use cornstarch. It helps thicken the juices released by the fruit.
• Don’t pour excess fruit liquid over the batter. Leave large puddles behind in the mixing bowl.
• Keep the batter thick. A thin cake batter can’t support a juicy fruit layer as well.
• Bake until the center is truly set. Fruit can make visual doneness cues tricky.
• Let it cool. The filling continues to settle and thicken after baking.

What Makes a Good Crumb Topping?

The best crumble isn’t perfectly uniform. Melted butter makes this version easy to mix, but once the flour and sugar are moistened, stop stirring. Then pinch some of the mixture into larger clusters and leave the rest loose.

Those different sizes bake at slightly different rates, giving you crisp little crumbs alongside softer buttery pieces instead of one flat layer of streusel gravel.

Strawberry-Rhubarb Crumb Cake Variations

• Strawberry-rhubarb almond: Add 1/4 teaspoon almond extract to the cake and sliced almonds to the crumble.
• Raspberry-rhubarb: Replace the strawberries with raspberries for an even tarter fruit layer.
• Strawberry-only: Use 2 cups chopped strawberries if rhubarb isn’t available.
• Ginger rhubarb: Add 1/2 teaspoon ground ginger to the crumble or a little finely chopped crystallized ginger.
• Orange strawberry-rhubarb: Replace the lemon juice with orange juice and add a little fresh orange zest.

What to Serve With Strawberry-Rhubarb Crumb Cake

For breakfast or brunch, serve it as it is with coffee or tea. Later, for dessert, warm slices are lovely with softly whipped cream, Greek yogurt, crème fraîche, or vanilla ice cream.

A light dusting of powdered sugar is plenty if you want to dress it up without hiding the crumble.

Storage and Freezing

Once completely cool, cover the cake and refrigerate it for up to 4 days. Over time, the crumb topping will gradually soften as it absorbs moisture from the fruit, although the flavor remains excellent.

For longer storage, you can freeze individual pieces for up to 3 months. Wrap them well and thaw in the refrigerator or at room temperature. Then warm them briefly in a low oven or toaster oven if you’d like to revive some of the crumble’s texture.

The First Hint of Spring

February isn’t spring, and this cake doesn’t need to pretend otherwise. After all, the days can still be cold, gardens can still be quiet, and rhubarb may still be coming from a freezer rather than the backyard.

Still, strawberry and rhubarb together point toward what’s coming. That’s enough for Bake With the Seasons: noticing the transition before the whole landscape has caught up.
