How to Make Low Calorie Strawberry Mousse Cake Recipe

Step 1: Prepare the Cake Layer

Start by lining an 8-inch springform pan with parchment paper at the bottom—this helps with easy removal later. Preheat your oven to 350˚F. Whisk the dry ingredients together first; this ensures even baking. Then, whip your eggs with stevia until light and fluffy, which will give the cake a tender crumb. Incorporate vanilla, oil, and yogurt to add moisture and subtle richness. Finally, gently combine the dry ingredients with the wet mixture and bake for about 20 to 25 minutes until a toothpick comes out clean. Cooling completely on a rack is crucial before moving on—this prevents the mousse from melting.

Step 2: Make the Strawberry Mousse

While the cake cools, bloom the unflavored gelatine in cold water so it dissolves smoothly later. Puree fresh strawberries until silky and simmer briefly to concentrate flavors. Stir in the gelatine while the mixture is still warm, then allow it to cool slightly. Meanwhile, whip the cream with stevia until stiff peaks form for that airy luxury. Blend Greek yogurt and evaporated milk, then fold in the strawberry puree followed by the whipped cream carefully, preserving the mousse’s light texture.

Step 3: Assemble and Chill

Place your cooled cake layer back into the springform pan and line the sides with parchment or acetate if available to get clean edges. Pour the sumptuous strawberry mousse over the cake, smoothing the top evenly. Refrigerate this for at least 4 hours or better yet, overnight, to let it set firmly and infuse the flavors.

Step 4: Create the Strawberry Jello Topping

Mix the strawberry jello and additional gelatine in boiling water until dissolved, then add cold water to cool the mixture. Arrange sliced fresh strawberries on top of your mousse cake, then gently pour the jello over them. This topping not only adds a stunning glossy finish but also a lovely burst of strawberry flavor. Refrigerate until completely set, then your cake is ready for its grand debut.

Garnishes

Fresh mint leaves or a light dusting of unsweetened cocoa powder can add a beautiful contrast to the strawberry red and chocolate brown of the cake. Alternatively, a few whole strawberries artfully placed make it inviting and seasonal.

Side Dishes

This cake pairs wonderfully with a simple side of fresh berries or a scoop of low-fat vanilla frozen yogurt for an extra touch of indulgence that keeps the calories in check but the flavors fresh and fun.

Creative Ways to Present

Try serving individual portions in clear glass cups layered with extra berry compote or crushed almonds for crunch. Or slice the cake thinly and serve it alongside a light green tea or sparkling water with lemon for a refreshing finish to a meal.

Make Ahead and Storage

Storing Leftovers

Store your Low Calorie Strawberry Mousse Cake Recipe leftovers in an airtight container in the refrigerator. This cake stays fresh for up to 3 days, keeping its moist texture and vibrant flavor.

Freezing

If you want to keep the cake longer, it can be wrapped tightly with plastic wrap and frozen for up to one month. Thaw overnight in the fridge before serving to maintain the best texture of the mousse.

Reheating

This mousse cake is best enjoyed chilled and is not designed for reheating. Serving it cold ensures the mousse remains light and refreshing, exactly how it was intended.

FAQs

Can I substitute fresh strawberries with frozen for the mousse?

Yes, you can use frozen strawberries, but be sure to thaw and drain them well to avoid excess water which can affect the mousse texture.

Is this cake suitable for gluten-free diets?

This version uses all-purpose flour, so it is not gluten-free. However, you can experiment with gluten-free flour blends to make it safe for gluten-sensitive friends.

Can I use a different sweetener instead of stevia?

Absolutely! You can swap stevia with erythritol, monk fruit sweetener, or any alternative sweetener that measures equivalently, adjusting to taste.

What is the best way to cut this mousse cake cleanly?

Use a warm, sharp knife cleaned between cuts to ensure clean slices without smudging the mousse layers.

How low in calories is this cake compared to traditional mousse cakes?

This recipe is thoughtfully designed to be significantly lower in calories by using light dairy, natural sweeteners, and fresh fruit, making it a lighter but equally delightful treat.

  • 1/2 package (42 g) strawberry jello
  • 1 cup (250 ml) water
  • 1/2 envelope (3 g) unflavored gelatine

Instructions

  1. Prepare Cake Layer: Line the bottom of an 8-inch (20 cm) springform cake pan with parchment paper. Preheat oven to 350°F (175°C). In a medium bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt. In a mixer bowl, whisk eggs and stevia until fluffy (5-7 minutes). Add vanilla extract, then oil and yogurt; mix well. Sift dry ingredients into wet ingredients and fold gently with a spatula until smooth. Pour batter into pan and bake 20-25 minutes, until a toothpick comes out clean. Cool completely on a rack.
  2. Prepare Strawberry Mousse: In a small bowl, combine unflavored gelatine with 50 ml water and let bloom for 5 minutes. Cut strawberries into chunks and blend with a hand blender until smooth. Heat strawberry puree in a saucepan over medium heat to a simmer, stirring occasionally for 2 minutes. Remove from heat, stir in bloomed gelatin until dissolved; cool slightly. Whip chilled cream with stevia until stiff peaks form. In a separate bowl, whisk Greek yogurt and evaporated milk until combined. Gradually add warm strawberry puree to yogurt mixture and whisk. Gently fold in whipped cream, careful not to overmix.
  3. Assemble Cake and Mousse: Place cooled cake layer back into the springform pan. Optionally line sides with acetate or parchment paper. Pour mousse mixture over cake layer and spread evenly. Refrigerate for at least 4 hours or overnight until set.
  4. Prepare Topping: In a large bowl, combine strawberry jello powder with half envelope unflavored gelatine. Add 1/2 cup boiling water and stir until fully dissolved. Add 1/2 cup cold water and let cool completely. Arrange sliced strawberries on top of chilled mousse. Pour the cooled jello mixture evenly over strawberries. Refrigerate until topping is completely set.
  5. Serve: Remove cake from springform by running a knife along edges. Transfer to serving plate or cake stand. Slice and enjoy a refreshing, low-calorie strawberry mousse cake.

Notes

  • Use light oil such as canola or vegetable oil to keep the cake moist but low in fat.
  • Ensure gelatin is fully bloomed and dissolved to achieve smooth mousse texture.
  • Do not overmix whipped cream with the strawberry mixture to maintain mousse lightness.
  • Refrigerate mousse layer for at least 4 hours—overnight is best for firm setting.
  • Optional: line springform sides with acetate paper for a cleaner cake release.
  • Stevia used as a sugar substitute to keep the recipe low calorie.
