Ingredients:
- 375g All purpose flour
- 250g Granulated Monk fruit sweetener
- 1 tsp Baking soda
- 0.5 tsp Salt
- 225g Unsalted butter, room temperature, cubed
- 3 Large egg whites, room temperature
- 240ml Low-fat buttermilk
- 2 tbsp Concentrated beet juice
- 1 tsp Pure vanilla bean paste
- 450g Unsalted butter, slightly cool
- 300g Powdered Erythritol, sifted
- 60ml Strawberry reduction (from 1 cup frozen strawberries)
- 0.5 tsp Rose water
- 1 pinch Himalayan sea salt
Instructions:
- Simmer the fruit. Reduce 1 cup of frozen strawberries in a small saucepan over medium heat until you have exactly 60ml of thick syrup. Note: This concentrates the flavor and removes excess water.
- Prep the pans. Grease two 8 inch pans and line the bottoms with parchment paper. Note: This prevents the delicate pink edges from sticking and tearing.
- Mix dry ingredients. Combine 375g flour, 250g monk fruit, baking soda, and salt in the bowl of a stand mixer. Note: Sifting these together ensures even distribution of the leavening agent.
- Incorporate the butter. Add 225g cubed room temp butter to the dry mix and beat on low until the mixture looks like fine, sandy crumbs. Note: This is the reverse creaming method that creates the velvet texture.
- Whisk the liquids. In a separate jug, blend 240ml buttermilk, 3 egg whites, 2 tbsp beet juice, and vanilla paste. Note: Adding the color to the liquid ensures a streak free, uniform blush.
- Combine the batter. Slowly pour the liquid into the flour butter mix and beat for 2 minutes until the batter is pale pink and glossy. Note: This aeration is what gives the cake its lift.
- Bake the sponge. Divide the batter and bake for 35 minutes until the tops spring back when lightly touched. Note: Internal temp should reach exactly 98°C for the perfect moistness.
- Whip the frosting. Beat 450g butter with 300g powdered erythritol until the mixture is billowy and white. Note: This can take 5-7 minutes; don't rush the process.
- Flavor and color. Fold in the 60ml strawberry reduction and 0.5 tsp rose water until the frosting is a uniform pale blush. Note: Add a pinch of sea salt to brighten the fruit notes.
- Final decoration. Stack the cooled cakes with a thick layer of frosting and finish with elegant, petal like swooshes using an offset spatula.
