This version balances a rich, buttery cake base with tart berries and a delicate spice topping for a bake that’s both nostalgic and crowd-pleasing.

Whether you serve it warm from the oven or enjoy it chilled the next day, this homemade cake stays moist and flavorful with every bite.

Ingredients Overview

Each ingredient in this recipe works to build a cake that’s moist, flavorful, and perfectly textured. Here’s what you’ll need and why it matters.

All-Purpose Flour

Forms the base of the cake. Be sure to spoon and level for accurate measurement to avoid a dense crumb.

Unsalted Butter

The key to that soft, melt-in-your-mouth texture. Room temperature butter creams with sugar to trap air and keep the cake fluffy and rich.

Granulated Sugar

Adds sweetness and helps create a golden, caramelized crust. You can use half white and half light brown sugar for deeper flavor.

Eggs

Provide structure and tenderness. Large eggs at room temperature mix more evenly and help the cake rise properly.

Sour Cream or Greek Yogurt

Keeps the cake ultra-moist and adds slight tang, balancing the sweetness of the berries and streusel.

Milk

Loosens the batter and keeps it soft without thinning the structure. Whole milk or 2% both work well.

Vanilla Extract

Adds warmth and depth to the cake’s flavor.

Baking Powder & Baking Soda

The combination gives the cake a light lift and just the right rise.

Blueberries

Use fresh or frozen (no need to thaw frozen berries). Toss them with a spoonful of flour to prevent sinking during baking.

Streusel Topping

A mix of flour, brown sugar, butter, and cinnamon that bakes into a crunchy, golden crown. Optional but highly recommended.

Step-by-Step Instructions

This cake comes together quickly and bakes up beautifully in a square or round pan. Here’s how to do it step by step.

1. Preheat and Prepare Pan

Preheat your oven to 350°F (175°C). Grease and line an 8×8-inch baking dish or round cake pan with parchment paper.

2. Make the Streusel Topping

In a small bowl, combine:

• ⅓ cup all-purpose flour

• ¼ cup brown sugar

• ½ tsp ground cinnamon

• 3 tbsp cold unsalted butter, cubed

4. Fold in the Blueberries

Toss 1 cup blueberries with 1 tsp flour, then fold gently into the batter to avoid crushing.

5. Assemble and Bake

1. Spread batter evenly into prepared pan.

2. Sprinkle streusel topping evenly across the surface.
