What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, with fresh strawberries adding that seasonal pop of color and taste. Here’s what you’ll need:

• For the Cake Batter:
• All-purpose flour – 2 cups (240g), sifted (I prefer King Arthur for best texture)
• Baking powder – 2 tsp
• Salt – ¼ tsp
• Unsalted butter – ½ cup (115g), softened (room temperature is key)
• Granulated sugar – 1 cup (200g)
• Large eggs – 3, room temperature (lets the batter rise evenly)
• Pure vanilla extract – 1 tsp
• Whole milk – ¾ cup (180ml), warmed slightly
• For the Creamy Strawberry Mousse:
• Fresh strawberries – 1 ½ cups (225g), hulled and chopped
• Heavy cream – 1 cup (240ml), cold
• Sugar – ¼ cup (50g)
• Gelatin powder – 1 tsp (optional, for stability)
• Cold water – 2 tbsp (to bloom gelatin)
• For the Crunchy Topping:
• Rolled oats – ½ cup (45g)
• Chopped almonds or pecans – ¼ cup (30g), toasted
• Brown sugar – ¼ cup (50g)
• Unsalted butter – 2 tbsp (30g), melted
• Ground cinnamon – ½ tsp (adds warm flavor)

Ingredient Tips: If you want a gluten-free version, swap the all-purpose flour for a gluten-free blend like Bob’s Red Mill 1-to-1. For dairy-free, use coconut cream instead of heavy cream and a plant-based butter alternative. In summer, fresh strawberries are best, but frozen (thawed and drained) work in a pinch.

Equipment Needed

• 9-inch (23 cm) round cake pan – I like nonstick for easy release, but you can line with parchment paper instead.
• Mixing bowls – one large for the batter, one medium for the mousse.
• Electric mixer or stand mixer – makes whipping cream and batter a breeze; handheld mixers work fine too.
• Spatula – for folding the mousse gently.
• Whisk – handy for mixing dry ingredients and blooming gelatin.
• Food processor or blender – optional but helpful to puree strawberries smoothly.
• Measuring cups and spoons – for precise ingredient amounts.

If you don’t have a stand mixer, no worries! Just give the batter and cream a little extra elbow grease. For the crunchy topping, a small skillet for toasting nuts and oats brings out the best flavors—if you don’t have one, you can toast in the oven on a baking sheet at 350°F (175°C) for about 8 minutes.

Preparation Method

1. Preheat and Prep: Heat your oven to 350°F (175°C). Grease your 9-inch cake pan with butter and lightly dust with flour or line with parchment paper to avoid sticking. This sets the stage for a perfect cake base.
2. Mix Dry Ingredients: In a medium bowl, whisk together 2 cups (240g) sifted all-purpose flour, 2 tsp baking powder, and ¼ tsp salt. Set aside. This ensures even distribution of leavening agents for a nice rise.
3. Cream Butter and Sugar: Using an electric mixer, beat ½ cup (115g) softened unsalted butter with 1 cup (200g) granulated sugar until light and fluffy, about 3-4 minutes. The texture should be pale and airy, which traps air for a tender crumb.
4. Add Eggs and Vanilla: Beat in 3 room-temperature eggs one at a time, mixing well after each addition, then stir in 1 tsp vanilla extract. This step builds structure and flavor.
5. Alternate Adding Dry and Milk: Gradually add the dry ingredients in three parts, alternating with ¾ cup (180ml) warmed whole milk, beginning and ending with the dry mix. Mix gently until just combined—overmixing can toughen the cake.
6. Pour and Bake: Pour the batter into your prepared pan, smoothing the top with a spatula. Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean. Your kitchen will smell like strawberry heaven soon—patience!
7. Prepare the Mousse: While the cake bakes, sprinkle 1 tsp gelatin over 2 tbsp cold water and let it bloom for 5 minutes. In a blender, puree 1 ½ cups chopped fresh strawberries until smooth. Warm the gelatin gently until dissolved and stir it into the strawberry puree.
8. Whip the Cream: In a cold bowl, whip 1 cup (240ml) heavy cream with ¼ cup (50g) sugar until soft peaks form. Gently fold the strawberry-gelatin mixture into the whipped cream, careful not to deflate it. Chill the mousse in the fridge.
9. Make the Crunchy Topping: In a bowl, combine ½ cup (45g) rolled oats, ¼ cup (30g) toasted chopped nuts, ¼ cup (50g) brown sugar, 2 tbsp (30g) melted butter, and ½ tsp ground cinnamon. Mix well until clumps form.
10. Toast the Topping: Spread the mixture on a baking sheet and toast in the oven at 350°F (175°C) for 8-10 minutes, stirring halfway, until golden and fragrant. Let cool.
11. Assemble the Cake: Once the cake is completely cooled, spread the creamy strawberry mousse evenly over the top. Sprinkle the crunchy topping generously, pressing lightly so it sticks. Refrigerate for at least one hour to let the mousse set beautifully before serving.

Pro tip: Don’t rush cooling the cake; warm cake will melt the mousse and make the topping soggy. Give yourself time for the flavors to meld—it pays off!

Cooking Tips & Techniques

Here’s what I’ve learned after many batches of this strawberry crunch cake:

• Beat Butter and Sugar Well: Creaming these ingredients until fluffy traps air, which is key for a light cake texture. Don’t skip this step or rush it!
• Room Temperature Ingredients: Eggs and butter at room temp mix more evenly, preventing lumps and ensuring a smooth batter.
• Gentle Folding: When incorporating puree into whipped cream, fold gently to keep that mousse airy and light rather than dense.
• Don’t Overbake: Keep an eye on the cake from minute 30 onward. Overbaking leads to dryness, and nobody wants that.
• Toasting Nuts and Oats: This step unlocks nutty aromas and crunch. Stir often to prevent burning and get even color.
• Chill Time: The mousse needs at least an hour to set properly. Use this time to prep your crunchy topping or clean up.
• Multitasking: While the cake is in the oven, use that window to whip the mousse. Saves time and keeps momentum going.

Trust me, following these tips will make your easy strawberry crunch cake shine every time.

Variations & Adaptations

If you want to switch things up, here are some tasty ways to make this cake your own:

• Dietary Twist: Substitute all-purpose flour with almond flour for gluten-free, and swap heavy cream with coconut cream for a dairy-free mousse. The coconut adds a subtle tropical note that pairs surprisingly well with strawberries.
• Seasonal Flavors: Use fresh raspberries or blueberries instead of strawberries. Or mix in chopped peaches for a summer vibe. The mousse adapts beautifully to whatever berry you choose.
• Cocoa Crunch: Add 2 tbsp unsweetened cocoa powder to the cake batter for a chocolate version, and mix cocoa nibs into the crunchy topping. Chocolate and strawberry? Always a winner.
• Crunchy Swap: Instead of oats and nuts, try crushed graham crackers or pretzels for a salty-sweet contrast. I once tried crushed pistachios with a drizzle of honey for a fancy spin—highly recommend.

Feel free to experiment with what you have on hand. This recipe is forgiving and welcomes creativity!

Serving & Storage Suggestions

Serve this easy strawberry crunch cake chilled for the best mousse texture and freshest flavor. A slice with a dollop of extra whipped cream or a scoop of vanilla ice cream pairs wonderfully. For drinks, try a light rosé, sparkling water with lemon, or even a hot cup of tea.

To store, cover the cake tightly with plastic wrap or use an airtight container. It stays fresh in the fridge for up to 3 days, but honestly, it rarely lasts that long! You can freeze it without the crunchy topping for up to 2 months—just thaw overnight in the fridge and add the topping fresh before serving.

Reheat is not recommended since the mousse texture changes, but if you want to warm a slice, remove the mousse layer and enjoy the cake base on its own, lightly toasted or warmed in the oven.

Flavors actually deepen after resting a few hours in the fridge, so if you can wait, your patience will be rewarded with a more melded, harmonious taste.

Nutritional Information & Benefits

This easy strawberry crunch cake delivers around 320 calories per slice (based on 12 servings), with a balanced mix of carbohydrates, fat, and protein. Strawberries add vitamin C and antioxidants, while nuts in the topping contribute healthy fats and fiber.

Keep in mind, this is a dessert meant for enjoyment and occasional treats, but it’s made with wholesome ingredients that bring real flavor and texture rather than artificial fillers.
