Creating the Nova Scotia Blueberry Cream Cake can be straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour three 8-inch round cake pans.
2. Mix Dry Ingredients: In a bowl, combine the flour, baking powder, baking soda, and salt. Whisk together and set aside.
3. Cream Butter and Sugar: In a separate bowl, cream the softened butter and granulated sugar until light and fluffy (about 5 minutes).
4. Add Eggs: Add the eggs one at a time, mixing well after each addition.
5. Incorporate Milk: Slowly add the whole milk to the mixture, blending until smooth.
6. Combine Dry and Wet Ingredients: Gradually add the dry mix to the wet ingredients, blending just until combined. Avoid overmixing.
7. Add the Blueberries: Gently fold in the fresh blueberries to the batter.
8. Divide Batter: Pour the batter evenly into the prepared cake pans.
9. Bake: Place in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
10. Cool: Remove cakes from the oven, allow them to cool in the pans for 10 minutes, then transfer to wire racks to cool completely.
11. Prepare Cream Filling: In a separate bowl, beat the heavy whipping cream until soft peaks form. Gradually add powdered sugar and vanilla extract until stiff peaks form.
12. Layer the Cake: Once the cakes are cool, place one layer on a serving plate. Spread a layer of the whipped cream over it, followed by another layer of cake. Repeat with the next layer.
13. Final Layer: Top with the last layer of cake and use the remaining whipped cream to frost the top and sides. Garnish with fresh blueberries and lemon zest, if desired.

With these steps, you will create a stunning and delicious Nova Scotia Blueberry Cream Cake that is sure to impress.
