This moist keto pound cake is flavoured with blackberries and lemon for a sweet but sharp taste. Baked with coconut flour it surprisingly light due to the addition of sour cream.
I had some blackberries and sour cream left over in the fridge and thought that I could either (a) Eat them together in a bowl (b) Make a cake. The Chief Taster's choice won, so I decided that I would try a low carb pound cake with coconut flour and added some lemon to give the cake a bit more flavour.

Is sour cream keto?
Thankfully sour cream is fine for a keto lifestyle. It's one of my favourite dairy products and part of my weekly grocery shop! According to the USDA, 12g of sour cream (a tablespoon) has 2.3 g fat, 0.3 g protein, and 0.5 g carbohydrates, with only 24 calories.

This is an easy cake to make. You mix the dry ingredients in one bowl and the wet ingredients in another bowl. Then combine the two and a sour cream pound cake is ready to bake!

Recipe Tips
I used a 1 pound loaf tin measuring 8. 5 x 4. 5 x 2. 75 inches. The one I used has high edges and seems to always give great results.
If you don't have blackberries, blueberries would be a great substitution.
