This keto raspberry cake is perfect for a romantic dinner for 2. It has a fluffy almond flour sponge, is filled with raspberries and covered in a luscious sugar free cream cheese frosting.
With Valentine's Day just around the corner, I wanted to come up with a new cake recipe for two. Over the last few years, we have been making either my Keto lava cake with its chocolatey gooey centre or this carrot cake for 2.
This year, I'm feeling like something fruity. That's how the idea for this keto raspberry cake came about!
Can I have raspberries on keto?
Raspberries are a great choice of fruit when you're on a low carb diet. ½ cup of raspberries contain just 3.5g net carbs - less than blueberries.
I often eat a handful raspberries for breakfast with yoghurt or my low carb granola. But of course, raspberries are wonderful in desserts!
A single serve low carb raspberry cake
I recently posted a quite wonderful recipe for a raspberry filled Victoria sponge cake. However, it's not always practical to make a huge cake that feeds 12.
Too many leftovers = too much temptation!
That's where this recipe comes in. I wrote it for 2 people sharing, but you can easily double or triple it.
Here are the ingredients you need to make the cake:
Egg - large
Powdered sweetener - I used an erythritol monk fruit sweetener blend
Butter - melted and cooled
Almond flour - I used ground almonds, which is equivalent to regular almond flour in the US. However, super fine almond flour should also work well.
CREAM CHEESE FROSTING
Cream cheese - I used Philadelphia.
Butter - Should be room temperature.
Powdered sweetener - increase sweetener to ½ cup if you like things sweet.
⅓ cup fresh raspberries
How to make keto raspberry cake
Add the egg and 2 tablespoons of powdered sweetener to a mixing bowl. Whisk on high for 2 minutes until super fluffy.
Add the yoghurt, melted and cooled butter and the vanilla. Whisk to combine.
Now add the dry ingredients to the wet and mix well to combine.
Grease a ramekin well with soft butter. This is an important step if you want to turn your cake out onto a plate without it sticking. Fill in the batter and bake in the oven for 20 - 22 minutes.
Start checking it at about 15 minutes. It is done when you can insert and remove a skewer without batter sticking.
While the cake is baking, whisk all ingredients for frosting together in a bowl until smooth. It's best to use room temperature butter for this and then cool the frosting in the fridge to firm it up.
Allow the cake to stand in the ramekin for 5 minutes. Then, turn it onto a baking rack to fully cool.
Cut in half horizontally and add 4 raspberries to the base half and some frosting to the top half. Put the frosted half on top of the raspberry layer and press down.
Add the rest of the cooled frosting round the sides using a palate knife.
Optional alternative: Mash the raspberries first and spread them on the cake. When you then add the cream cheese frosting, the two will mix and turn the frosting pink. This also looks great and tastes yum!
If necessary, place the cake in the fridge for the frosting to firm up further. I left mine in for about 30 minutes.
Last, dust it in a little freeze-dried raspberry powder, add fresh raspberries, slice and serve.
Make the cake in the microwave: Start with 2 minutes, then continue in 10 second increments until the sponge is done. My guess is this will take between 2 and 4 minutes, depending on the wattage of your microwave.
Note that the cake won't turn out as pretty and smooth on the sides when microwaving.
No almond flour: For a nut free cake, replace the almond flour with ⅓ the amount of coconut flour.
No coconut flour: Use 3 tablespoons more almond flour instead of the coconut flour.
Make it dairy free: Replace the butter with coconut oil and make a simple sugar free icing instead of the cream cheese frosting. The icing I used in my coconut flour cake would work well here.
You can make the sponge cake up to 3 days ahead. It can also be frozen for up to 3 months.
After you frost the cake, it's best to store it in the fridge and eat within 2 days.
