Ingredients

Scale

Batter

2 cups flour

1 teaspoon baking powder

1 teaspoon baking soda

1/2 teaspoon salt

1 cup plain greek yogurt

1 egg at room temperature

3 tablespoons half and half or milk

1/4 cup butter, melted

1/4 cup canola oil

1/2 cup sugar

1 teaspoon vanilla

3 tablespoons fresh lemon juice (You will need 1 large lemon or 2 small lemons for the entire recipe)

1 teaspoon lemon zest

1 1/2 cup fresh or frozen blueberries

Crumble Mix

1/3 cup all-purpose flour

2 tablespoons brown sugar

2 tablespoons butter, melted

1 teaspoon lemon zest

Cream Cheese Topping

4 oz. Cream cheese

2 tablespoons milk

1 teaspoon lemon zest

2 tablespoons lemon juice

Instructions

  1. Prepare the baking pan and the ovenCut a strip of  parchment paper measuring 16 ½ inches long and wide enough to line the bottom of a 9x9 baking pan. Place the parchment in the pan leaving 2 inches of overhang. This makes it easier to lift the cake out of the pan later. Preheat your oven to 350 degrees.
  2.  Make the crumb toppingCombine the flour, brown sugar, melted butter and lemon zest in a small bowl. Cover and set aside.
  3. Combine the dry ingredientsUsing a medium sized bowl, combine the flour, baking powder, baking soda, and salt. Whisk (affiliate link) to combine. Set aside.
  4. Combine the wet ingredientsPour the yogurt into a large bowl, add the egg and whisk (affiliate link) to combine. Add the milk, melted butter, oil, sugar, vanilla, lemon zest and juice, whisk (affiliate link) until well combined. It should be a smooth consistency.
  5. Combine the wet into the dry ingredientsAdd the dry ingredients to the wet in batches. Add ⅓ of the flour mixture to the wet and fold using a flexible spatula. When most of the flour has been incorporated, add half of the remaining flour mixture, fold again, then add the remaining flour and fold until there is no more dry flour. Your batter should be light and fluffy.
  6. Assemble - Spoon half the batter into the pan and spread on the bottom of the pan, and 

    sprinkle half of the crumble mixture over the batter. 

  7. Top the crumble layer with the blueberries. If you are using frozen blueberries don’t thaw them. Keep them frozen until you are ready to layer them in your batter.

  8. Spoon the remaining batter over the blueberries and spread evenly, then sprinkle the remaining crumble over the top of the batter. 

  9. Bake the cake in the middle of the oven for 25-30 minutes or until a toothpick inserted comes out clean and the cake springs back when you touch the top.

  10. Make the cream toppingWhile the cake is baking in the oven, use a small bowl to whisk (affiliate link) all of the cream topping ingredients together until  smooth and creamy. (Depending on the temperature of your kitchen, you may need to microwave your cream cheese for a few seconds to soften before adding the remaining ingredients.) Transfer topping to a piping bag (affiliate link) or zip bag and set aside.
  11. Cool: Remove from the oven and allow to cool. Once the cake has cooled, use the parchment paper to lift the cake out of the pan and place on a cutting board or other flat surface.

  12.  Top cake with cream topping: Spread or drizzle the cream topping over the top of the cake using a piping bag (affiliate link) or a zip bag with a corner of the bag cut.

  13. Serve:Slice the cake into 16 squares and serve at room temperature or slightly warm. 

Notes

If you are using frozen blueberries don’t thaw them. Keep them frozen until you are ready to layer them in your batter. Thawing your berries will create liquid on your berries causing the color to bleed.

How to Freeze Your Fresh Blueberries

Wash and dry the blueberries.

Place blueberries in a single layer on a parchment lined baking sheet pan. Place sheet pan in the freezer and freeze until blueberries are frozen solid.

Transfer frozen blueberries to a plastic zip bag or container with an airtight lid. If you are using a plastic zip bag, squeeze out as much air as possible before sealing the bag. Label and place in the freezer. I recommend using blueberries within 6 months.
