More detailed directions (with pictures)
For the best results, all ingredients for the cake should be at room temperature except the cake filling (which should be chilled in the fridge ya turkey).
Mix the dry ingredients (flour, baking powder, and baking soda) by passing them through a sieve a couple of times.
Add milk to a mixing bowl
Add the erythritol and stevia to the milk.
Add dry ingredients to the mix.
Add butter/oil to the mix
In a separate bowl, beat the eggs well with a mixer until it turns pale yellow in color.
Mix the egg mixture with the cake mix.
Add the red color to the mix.
Mix all the ingredients with a mixer.
Add the cake mix to a springform cake tin.
Place the cake tin in a pre-heated oven for 40-45 minutes, or until a toothpick comes out clean. Let it cool on a wire rack (or you know, anywhere at all).
Filling: while the cake is in the oven, beat the cream with an electric mixer. The cream needs to be very cold/chilled before beating with the electric mixer. Add erythritol to the mix and beat it again!
This will take around 2 minutes with an electric mixer.
Cut the cake in 2 equal parts. Spread half of the cake filling on the base.
Spread the rest of the cream on the top of the cake.
Garnish with fresh berries
