Strawberry yogurt crumb bars bring together fresh berries with a creamy yogurt layer all nestled between buttery crumbs. They are a magical way to celebrate spring sweetness.
Line a 9x13-inch baking pan with paper parchment. (see note)
Preheat the oven to 350°F.
In a large bowl, combine together the 1½ cups all-purpose flour, 1¾ cup rolled oats, ¾ cup granulated sugar, 1 pinch salt, and ½ teaspoon baking powder.
Add the ⅔ cup unsalted butter and 1 teaspoon vanilla extract. Stir until well combined and crumbly. (I use a stand mixer with the paddle attachment but can be made by hand).
Set aside 1 cup of the mixture for topping.
Put remaining mixture into the prepared pan and spread out evenly. Press it into a flat layer to form a crust. It may look like it won’t stick together, but it will. (You can use the flat bottom of a measuring cup to press the crust).
In another bowl, mix together the 3 cups plain Greek yogurt, ⅓ cup granulated sugar, and 2 Tablespoons cornstarch. Spread the yogurt mixture over the crust.
Spread the ⅓ cup strawberry jam over the yogurt mixture.
Slice the 12 oz. fresh strawberries and dot them over the jam.
Sprinkle the remaining crumble mixture over the strawberries.
Bake for 45-50 minutes or until golden.
Leave to cool in the pan completely before cutting into 12 squares to serve.
Store in the refrigerator until ready to serve. They can be stored safely for at least 4 days.
Notes
Make sure the butter is soft: Cut the butter into chunks and leave it at room temperature for around 1 hour before baking.If you don’t want to cut the slices in your pan, leave 1 inch of paper parchment hanging over the sides of the pan. It will be easier to lift the cake from the pan.
