Ingredients
  

For the Cake
  • 2 cups all-purpose flour
  • ¾ cup granulated sugar
  • 2 teaspoons baking powder
  • ½ teaspoon salt
  • 1 large egg
  • ¾ cup milk any kind
  • ¼ cup vegetable oil or melted butter
  • 1 teaspoon vanilla extract
  • 2 cups frozen blueberries do not thaw
  • 1 tablespoon extra flour for tossing with the berries
For the Crumble Topping
  • ½ cup granulated sugar
  • ⅓ cup all-purpose flour
  • ¼ cup cold butter cubed
  • 1 teaspoon ground cinnamon

Method
 

Step 1
  1. Get Ready: Preheat your oven to 375°F (190°C). Grease an 8x8 inch or 9x9 inch square baking pan.
Step 2
  1. Make the Topping First: In a small bowl, mix the ½ cup sugar, ⅓ cup flour, and cinnamon. Add the cold, cubed butter. Use a fork or your fingers to mash it all together until it looks like coarse, wet sand. Set this aside.
Step 3
  1. Prep the Berries: In another small bowl, toss the frozen blueberries with that 1 tablespoon of flour. This little trick helps prevent them from all sinking to the bottom and turning your batter purple!
Step 4
  1. Mix the Dry Stuff: In a large bowl, whisk together the 2 cups of flour, ¾ cup sugar, baking powder, and salt.
Step 5
  1. Mix the Wet Stuff: In a separate bowl or a measuring jug, beat the egg lightly. Then whisk in the milk, oil (or melted butter), and vanilla until combined.
Step 6
  1. Combine Everything: Pour the wet ingredients into the dry ingredients. Stir with a spatula just until combined. A few lumps are totally fine—overmixing makes a tough cake. Gently fold in the flour-coated blueberries.
Step 7
  1. Bake: Pour the batter into your prepared pan and spread it out evenly. Sprinkle the crumble topping over the entire surface. Pop it in the oven for 40-50 minutes. You’ll know it’s done when a toothpick poked into the center of the cake (not a blueberry!) comes out clean.
Step 8
  1. The Hardest Part—Wait!: Let the cake cool in the pan on a wire rack for at least 30 minutes before you slice it. This helps it set perfectly.
