If you love blueberry and lemon treats, this blueberry lemon snack cake is a must make recipe! It's perfect in so many ways. Moist, flavorful cake that's easy to make. A deliciously citrusy lemon sauce that complements the blueberries perfectly. A cake that's no-fuss when it comes to decorating. (Seriously. Just pour the sauce over the cake, and garnish with a few lemon slices and fresh berries, if you want to.)

This cake is simple enough to make just-for-fun at home, yet impressive enough for a special occasion. I love when desserts can pull double-duty like that! Plus, you have the option to bake the cake in a round 9 inch pan or a square 8 inch pan without having to make any alterations to the recipe.

How to Make Blueberry Snack Cake with Lemon Sauce from Scratch

• Prep your pan. This cake can be baked in a 9 inch round cake pan or an 8 inch square pan (metal is best). Be sure to line your pan with parchment paper (and spray the side of the pan, if using a round pan).
• Toss fresh blueberries with a bit of flour. (Dusting the berries with flour before adding them to the batter will ensure that they "float" throughout your baked goods rather than sinking to the bottom of the pan.) Set the berries aside. Combine flour, baking soda, and salt and set aside.
• Cream butter and sugar, then beat in an egg. Stir the flour mixture into the butter mixture, then stir in milk. Finally, fold in the berries.
• Pour the batter into the prepared pan and bake until the cake is golden brown, about 50 minutes. Let cool on a wire rack.
• As the cake cools, prepare the lemon sauce by combining sugar, cornstarch, and salt in a saucepan. Add boiling water and cook the mixture for about 5 minutes until thickened. Add lemon zest, lemon juice, and cubed butter and continue to cook the sauce until it comes to a rolling boil and becomes thick enough to coat the back of a spoon. Let the sauce cool a bit, and it will thicken more as it cools.
• Pour the mostly cooled sauce over the still warm cake. Garnish with lemon slices and fresh strawberries, if desired, slice, and serve warm.

Should blueberry lemon snack cake be refrigerated?

Nope. The refrigerator will dry out the cake more quickly, and the cold temperature will dull the brightness of the fruit flavors in both the cake and the sauce. This cake should be stored at room temperature in an airtight container for up to 3 days.

Instructions

• Preheat oven to 350ºF. Line a 9 inch round or 8 inch square metal baking pan with parchment and set aside. (If using a round pan, spray pan with cooking spray before placing parchment into the pan, since parchment will not cover sides of pan.)

Make the blueberry cake. 

• Place blueberries in a small bowl and toss with 2 Tablespoons flour until all berries are dusted with flour. Set aside.
• In a medium bowl combine remaining 1 ¼ cups flour, baking powder, and salt. Whisk to combine; set aside.
• In the bowl of a stand mixer (or in a large bowl using a handheld electric mixer), cream butter and sugar. Add egg and beat well to combine.
• With the mixer running on low speed, add flour mixture and stir just until combined. Then add the milk, stirring on medium speed just until blended. Add the floured blueberries and fold them into the batter using a spatula or wooden spoon.
• Pour the batter into the prepared baking pan and use a spatula or spoon to spread it gently into a smooth, even layer. Bake for 45-50 minutes or until cake is golden and a toothpick inserted into the center of the cake comes out clean. Let the cake cool in the pan on a wire rack before removing from the pan.

Make lemon sauce.

• In a medium saucepan, add sugar, cornstarch, and salt. Whisk to combine and set aside.
• Boil water and add to the saucepan with the sugar.
• Cook the mixture over medium-high heat, stirring constantly, until it comes to a gentle boil and begins to thicken and become translucent, about 5 minutes. The mixture should be thick enough to coat the back of a spoon. 
• Add the lemon zest and juice to the pan and whisk to blend. Add the butter to the pan, 1 cube at a time, and whisk until melted.
• Continue to cook the mixture for about 5 more minutes, stirring constantly. The sauce will come to a rolling boil and is ready when it's thick enough to coat the back of a spoon.
• Allow the sauce to cool for at least 20 minutes before pouring over the cake. The sauce will continue to thicken as it cools, and it should be warm but not hot when poured over the cake.
• Slice the cake and serve warm or at room temperature. Garnish with lemon slices and fresh blueberries, if desired.

Notes

Storage: Store leftover cake in an airtight container at room temperature for up to 3 days.
