Blueberry Ginger Buttermilk Cake

A showstopper on any table

Back to Blog

A showstopper on any table — bursting with blueberries and a warm ginger spice that lingers long after the last bite. The buttermilk keeps this cake incredibly moist and tender, while the fresh ginger adds a gentle heat that makes the blueberries taste even more vibrant. It's elegant enough for a dinner party and simple enough for a Sunday morning with coffee.

Prep Time20 min
Cook Time45 min
Servings8–10 slices

Ingredients

  • 2 cups all-purpose flour
  • 1½ tsp baking powder
  • ½ tsp baking soda
  • ½ tsp kosher salt
  • 1 tsp ground ginger
  • ½ tsp cinnamon
  • 1 tbsp fresh ginger, finely grated
  • ¾ cup unsalted butter, softened
  • 1¼ cups granulated sugar
  • 3 large eggs, room temperature
  • 1 tsp vanilla extract
  • 1 cup buttermilk
  • 2 cups fresh blueberries
  • 1 tbsp flour (for tossing blueberries)
  • Powdered sugar for dusting

Instructions

01

Prep

Preheat oven to 350°F. Grease and flour a 9-inch round cake pan or springform pan. Toss blueberries with 1 tbsp flour to prevent sinking — set aside.

02

Mix Dry Ingredients

Whisk together flour, baking powder, baking soda, salt, ground ginger, and cinnamon in a bowl. Set aside.

03

Cream Butter & Sugar

Beat softened butter and sugar together on medium-high speed for 3–4 minutes until light and fluffy. Add eggs one at a time, beating well after each. Mix in vanilla and fresh grated ginger.

04

Alternate Wet & Dry

With the mixer on low, add the flour mixture in three additions, alternating with the buttermilk (starting and ending with flour). Mix just until combined — don't overmix.

05

Fold in Blueberries

Gently fold in the floured blueberries with a rubber spatula. Pour batter into the prepared pan and smooth the top.

06

Bake

Bake 40–45 minutes until a toothpick inserted in the center comes out clean and the top is golden. If the top browns too quickly, tent loosely with foil.

07

Cool & Serve

Cool in the pan 15 minutes, then turn out onto a wire rack. Dust generously with powdered sugar before serving.

Robin's Tips & Variations

  • Frozen blueberries work well — don't thaw them before folding in, and expect a slightly longer bake time.
  • For extra ginger punch, add a tablespoon of crystallized ginger, finely chopped.
  • This cake keeps well at room temperature for 2 days, or refrigerated for up to 5 days.
  • A lemon glaze (powdered sugar + lemon juice) is a beautiful alternative to powdered sugar.
