This fluffy, airy keto Victoria sponge cake is so easy to make! It's a buttery yet light almond flour sponge filled with sugar free raspberry chia jam, whipped cream and fresh raspberries.

Victoria sponge cake is one of the great British dessert classics. It is a buttery two layer sponge cake that is filled with whipped cream and berries or jam. It makes a wonderful celebration cake or afternoon treat.
The recipe was made famous by Queen Victoria herself, who regularly used to enjoy a slice with her traditional afternoon tea!
The great thing about this gluten-free, sugar free sponge cake is that it looks super impressive, yet it's surprisingly simple to make.
And did I mention how delicious it is?

Ingredients

Below are the ingredients I used for this keto sponge cake:
Sponge
- Eggs - large and room temperature for a fluffier cake
- Lakanto Classic - this is a granulated sweetener
- Sour cream - you could use yoghurt instead. Room temperature is best here too!
- Butter
- Almond milk - or any nut/seed milk you prefer
- Vanilla and lemon zest for extra flavour
- Almond flour - I actually used ground almonds. This is the same as regular almond flour in the US. If your almond flour is extra fine, you may want to use 1-2 tablespoon less.
- Coconut flour - if possible, measure in weight rather than cups.
- Baking powder
Jam
- Raspberries - I used frozen because they are cheaper, but fresh also work
- Sweetener - it's optional here, but I like to add 1 tablespoon.
- Chia seeds - make sure they are ground
- A tiny splash of water
Filling and Topping
- Raspberries
- Heavy whipping cream (double cream) - I didn't sweeten the whipped cream in this recipe, but if you would like it a little sweeter, use my recipe for sugar free whipped cream.
- Powdered Lakanto to dust. I simply powdered some of the Lakanto Classic in my food processor. You could also use a coffee grinder or a pestle and mortar for this.

Instructions
This section contains step-by-step instructions and photos that show how to make this recipe. See the recipe card for full information on ingredients and quantities
Step 1: Preheat the oven to 180C / 350F. Line a small springform pan (7 inches) with parchment paper on the base and generously butter the sides.

Step 2: Separate the eggs and beat the egg whites until stiff.

Step 3: In a clean bowl, add the egg yolks and sweetener. Blend using an electric whisk for 2 minutes until pale and fluffy.
Step 4: Add the sour cream, melted butter, almond milk, vanilla and lemon zest. Whisk to combine.

Step 5: In another clean bowl, mix the almond flour, coconut flour and baking powder together.

Step 6: Add the dry ingredients to the wet and mix to combine with an electric whisk.
Step 7: Last, fold in the egg whites until combined. Don't over-mix to keep the air bubbles intact. This is important for an airy cake texture.

Step 8: Pour into your springform pan and level the top with a spatula.
Step 9: Bake until golden until you can insert and remove a skewer without it sticking.
Loosely cover the cake with a sheet of tin foil once it is golden on top, from about 45 minutes.

Step 10: While the cake is baking, add the frozen raspberries, sweetener and water to a pan. Simmer until the raspberries are soft. Mash with the back of a spatula. Turn off the heat and add the chia. Allow to fully cool to firm up.
Step 11: Whip the cream until just under stiff peaks.
Step 12: Cut the fully cooled cake in half lengthways using a sharp knife. Add a layer of raspberry jam and cream and top with raspberries. Add the top of the cake and dust with powdered sweetener. Slice and serve.
Recipe Variations
Make it nut free: For a sponge without almond flour, try this coconut flour cake. Slice in half and fill as per recipe.
For a strawberry keto Victoria sponge, use my sugar free strawberry jam. I can also see this cake work with my sugar free blueberry jam. Less traditional perhaps, but certainly delicious.
Dairy free? Use coconut oil instead of the butter and fill the cake with whipped coconut cream.
Bake in 2 cake tins: Separate the batter into two 7 inch springform tins and reduce the baking time to about 30-35 minutes.
It should be possible to use an 8 inch springform tin. This will make the layers thinner and the baking time will also reduce. I would test the cake at 40 minutes and see if it's done.

Storage
Refrigerator: Store in the fridge for up to 3 days.
Freezer: It's possible to freeze the cake for up to 3 months, although I find that whipped cream is not quite the same after defrosting.
I recommend that you freeze the sponge on its own. Defrost, and then add the filling just before serving.

I made this at the weekend but added almond essence and lemon zest and itโs so morish and tasty. Really easy as long as you have all the ingredients- and I used some home made straw berry preserve so it was delicious. So helpful to have low carb sweet treats on hand. I had to cut the cake in two as I wonโt eat all it in a few days so Iโve frozen it. But Iโm sure that will be fine.
Is there one general sugar free sweetener you could suggest for cake making? There are so many, and some just are plain unhealthy itโs so a bit of a nightmare. Thank you for sharing these easy low carb recipes.
Katrin Nรผrnberger
The sweeteners I use regularly are allulose, Lakanto monk fruit sweetener and Bocha Sweet. See what's available where you are (I often order from iherb). With allulose, you'll have to increase the amount used by a little as it has 70% of the sweetness of sugar. The others are 1:1 sugar replacements.

Hi Katrin, I'm planning on making this cake next month. Would it be possible to make it without the chia seeds and almond (or nut alternative) milk?
Katrin Nรผrnberger
Of course. You can use any milk instead of the almond milk. And you can either omit the chia seeds and continue cooking down the liquid, or use a little gelatine to thicken.
Hilda
I did it today, it is super delicious.
Thanks for the recipe.
Everything worked perfectly.
Deni
What if you don't have a spring form pan?
Katrin Nรผrnberger
You can make this in a regular round pan if you line the bottom with parchment, grease the sides very well, and run a knife around the edges before releasing the cake.
Monica
Can you use frozen blueberries instead of raspberries?
Katrin Nรผrnberger
Of course!
Patricia
For the filling, can I use frozen raspberries? Will they be runny?
Katrin Nรผrnberger
I made the jam with frozen raspberries. I would not use defrosted raspberries to add to the cake. Like you say, they would be mushy.
Alisha
Can you use rice flour in place of the other flours?
Katrin Nรผrnberger
I don't know whether rice flour would be a 1:1 substitution. My guess is that it is not as the consistency is very different to low carb flours.
