Directions

Preheat oven to 350°F (175°C). Grease and flour a 9-inch round or square baking pan.
In a large bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt.
In another bowl, beat together sugar, brown sugar, eggs, oil, milk, and vanilla until smooth.
Gradually add the dry ingredients to the wet mixture. Stir in hot water or coffee until the batter is smooth and slightly thin.
Toss blueberries in a spoonful of flour (to prevent sinking) and gently fold them into the batter.
Pour the batter into the prepared pan and smooth the top.
Bake for 40–45 minutes, or until a toothpick inserted in the center comes out clean.
Let cool completely before slicing. Serve plain, dusted with powdered sugar, or topped with whipped cream or chocolate ganache.

FAQs

Can I use frozen blueberries?

Yes, but do not thaw them first—fold them into the batter frozen to avoid excess moisture.

Will the blueberries sink to the bottom?

Dusting them lightly with flour before adding to the batter helps keep them evenly distributed.

Can I make this cake in advance?

Yes, it actually tastes better the next day as the flavors meld together.

What kind of cocoa powder is best?

Use unsweetened natural cocoa or Dutch-process cocoa for a deeper flavor.

Can I make it into cupcakes?

Yes, divide the batter into a lined muffin tin and bake for 18–22 minutes.

Do blueberries and chocolate really go well together?

Yes, the tartness of blueberries enhances and balances the richness of chocolate.

Can I frost this cake?

Absolutely—cream cheese frosting, whipped cream, or chocolate ganache all pair beautifully.

Can I use whole wheat flour?

Yes, but replace only half the flour for best texture, as whole wheat makes the cake denser.

How do I keep the cake moist?

Do not overbake, and store it properly in an airtight container. The blueberries also help keep it moist.

Is this cake very sweet?

It has a balanced sweetness, with the chocolate providing richness and the blueberries adding fruity brightness.
