Blueberries & Cream Crumb Bars

Blueberries and cream is a match made in heaven.  Although it is now possible to get blueberries year-round, this is the time of year that they are the most affordable. Fresh blueberries make a great snack on their own but when you add them to baked goods the results are amazing.

Recently I used them when I made some scones, but this time I wanted a creamy layer for them to nestle in.  While looking for recipes I saw a lot of blueberry crumb bars and a few blueberry custard bars, but none that combined the custard and a crumb topping.  I decided to use the base and crumb topping from my recent post for Razzeleberry bars and a custard filling, and the combination was a great success.

Last night I had a compulsory parent meeting for my daughters JV volleyball team, and there was to be a potluck afterwards, so I thought these would be perfect.  I think they must have been because when the container I brought them in was returned to me there were a few crumbs and a lone blueberry in the bottom.  I was so glad that I had kept a few small pieces at home or I would not have gotten to try the bars at all.

I just love the base of these bars.  The almond meal gives it such a distinct nutty taste, and the hint of lemon complimented the blueberries perfectly, and it just seems to melt in your mouth once you bite into it. They were prefect on their own, but I think that a la mode may just put them over the top.

  1. You know when the container comes back empty they were good. I have a thing for blueberries, well I have a thing for all baked goods, lol. But I have to say I wouldn't pass if one these was passed my way. Hope you are having a good week.

  2. You know, just when I think I'd found every great baking blog, I found yours! This must be my lucky day. I love blueberries, I love crumb cakes and I love creamy fillings (and I don't mean Jello instant pudding!). I can't wait to make this recipe tonight and bring it into the office tomorrow. Thank you so much!
