Cream together the butter and sugar until light in colour and fluffy.
Add in Eggs 1 at a time fully mixing in each one before adding the next.
Once all the eggs are in add the vanilla, lemon juice, lemon zest and oil.
In a seperate bowl mix together the dry ingredients. Slowly add the dry ingredients to the main bowl with the sugar and butter, alternating with the sour cream.
Fold in the Blueberries
Prepare the bundt pan with oil or butter and a light dusting of flour.
Add the cake batter.
Bake The Cake
Bake for 55-70 mins (i know this is a huge range but everyone's oven is so different!) You will know your cake is done when you insert a toothpick and it comes out with a clean crumb not cake batter 😋
Getting the Cake Out of the Pan
Once the cake has baked remove it from the oven and rest it upside down on a cooling rack. It should come out of the pan easily once it has cooled completely. If it is difficult to remove, run a butter knife along the edges and try to remove it again.
