Almost too pretty to eat (but too delicious not to!), these decadent blackberry custard bars pair a buttery shortbread crust with a silky, berry-studded filling.

I know spring is here because the days are starting to get longer and my allergies are in full swing. Despite my red eyes and sneezes, I adore this time of the year and love spending more time outdoors.
Spring isn’t just about the warm weather or pretty flowers. I love spring even more because my favorite fruits and vegetables are in season. And fresh fruits means, my favorite, fruit desserts!

- Add fruit. Scatter blackberries over the slightly cooled crust.
- Make the custard: Combine melted butter, milk, eggs, sugar, flour, salt and vanilla extract. Mix with an electric mixer until completely smooth. Pour the custard batter over the berries.
- Bake. Bake until custard is set about 30 minutes. Cool completely then refrigerate for 1 hour before cutting bars. Top with powdered sugar, if desired.

I enjoyed these beauties with my morning tea because well, if you can enjoy pancakes for breakfast, you certainly can have these bars in the morning, too!
They might scream summer, but you can also enjoy these all year long using most any sweet seasonal fruit.
If you want to try more fruit bars, you should most definitely try a family favorite blueberry lemon bars, my whole wheat berry bars or something more chocolatey like these raspberry cheesecake brownies!

Cookbook review. This wonderful recipe was created by a friend of mine, Jackie Bruchez from The Seaside Baker. Jackie is a talented baker and photographer. She has been tantalizing me with sweet creations for many years.
And when I heard about her cookbook, Decadent Fruit Desserts, she captured my heart before I saw a single photograph or recipe. I was able to test some of her recipes when she was writing her cookbook. Everything tasted INCREDIBLE!
I hope you order her cookbook and try more of her amazing recipes!
Storing/Freezing Instructions
TO STORE: Store any leftover bars in an airtight container and refrigerate for up to 4 days.
TO FREEZE: You can also freeze the bars. Transfer to a resealable bag or freezer safe container and freeze for up to 4 months.
Although blackberries were used for these custard bars, you can definitely use other berries like strawberries, blueberries and raspberries, too. I bet they would be just as delicious with chopped peaches or apricots, as well.
For these custard bars, fresh fruit is best. Frozen fruit because mushy when thawed and the texture and excess water will affect the custard being baked.

HI ! DO you think you could use frozen Berries?
Hi Elizabeth-
You can use frozen berries, but first thaw them completely and drain out the juices before mixing into the batter. The texture of the berries will be different than if you had used fresh berries.

Sounds like a good book, and this is a GREAT looking dish! Love this time of the year — we’re getting into berry season, and soon it’ll be stone fruit season. Bliss! 🙂
