Blueberry Ricotta Squares

Step 1
Preheat the oven to 350 degrees F (175 degrees C). Grease a 9-inch square baking dish.

Step 2
In a large bowl, stir together flour, 3/4 cup sugar, and baking powder. Add milk, shortening, 1 egg, and lemon extract; beat with an electric mixer on low speed for 1 minute, then beat on medium speed for 1 more minute. Spread batter evenly into the prepared pan; sprinkle with blueberries.

Step 3
In a medium bowl, stir together 2 beaten eggs, ricotta cheese, 1/3 cup sugar, and vanilla until well combined. Spoon over blueberries and spread evenly.

Step 4
Bake in the preheated oven until a knife inserted into the center comes out clean, 55 to 60 minutes. Cool completely before cutting into squares to serve.
