Instructions

Step 1: Prepare the Pans

Preheat your oven to 350°F (175°C). Grease and line two 8 inch round cake pans with parchment paper.

---

Step 2: Make the Blueberry Puree

Blend fresh blueberries until smooth. If you prefer a smoother cake texture, you can strain the puree to remove skins.

---

Step 3: Mix the Dry Ingredients

In a large bowl, whisk together the flour, sugar, baking soda, baking powder, and salt.

---

Step 4: Mix the Wet Ingredients

In another bowl, whisk together the buttermilk, melted butter, oil, eggs, lemon juice, vanilla extract, and blueberry puree.

If you are using food coloring, add it here until you reach your desired shade of blue.

---

Step 5: Combine

Pour the wet ingredients into the dry ingredients and gently mix until just combined. Do not overmix, as this helps keep the cake tender.

---

Step 6: Bake

Divide the batter evenly between the prepared pans.

Bake for 25 to 30 minutes, or until a toothpick inserted in the center comes out clean.

Let the cakes cool completely before frosting.

---

Step 7: Make the Frosting

In a large bowl, beat the cream cheese and butter until smooth and creamy.

Add powdered sugar gradually, then mix in the vanilla extract. Add milk a little at a time until the frosting is soft and spreadable.

---

Step 8: Assemble the Cake

Place one cake layer on a serving plate and spread a layer of frosting on top.

Add the second layer and frost the top and sides of the cake.

You can keep the finish simple or swirl the frosting for a soft, homey look.

A gentle mix keeps the crumb soft and velvety.

Adjust the Color Naturally

Frequently Asked Questions

Why is my cake not very blue?

Blueberries naturally give more of a purple tone. For a brighter blue, a small amount of food coloring helps.

Can I use frozen blueberries?

Yes, just thaw and drain them well before blending.

What makes this a velvet cake?

The combination of buttermilk, fat, and gentle mixing creates a soft, tender crumb similar to classic velvet cakes.

Can I make this ahead of time?

Yes. You can bake the layers a day ahead and frost before serving.

Can I use a different frosting?

Yes. Whipped cream frosting or a light buttercream both pair nicely with the blueberry flavor.
