I made this up because we needed a quick cake filling. You can use any berries. It also makes good syrup. Let sauce cool before filling your cake.

Very Good! I was very Impressed with the outcome! I did add a little bit of lemon juice. Like a table spoon because it was to sweet. But overall good! Read More

I did not care for this recipe. I wanted my filling to taste like berries. Not confectioners sugar. It's too overpowering. Didn't think it would make that big of a difference. Read More

I couldn't find the cornstarch and used rice flour instead, adding a little extra because I also added the juice of half a lemon. I also added a good pinch of salt. I think both were good additions and the results were spectacular for filling a butter pecan cake made from BC's mix. It's a good mix and not overly sweet like many. Read More

This recipe saved my life! I was making a bridal shower cake and ran out of granulated sugar for my blackberry filling and all I had was powdered sugar. Well I never made it with powdered sugar before and it turned out PERFECTLY! So thankful I found this recipe. The only changes I made was I lengthened the cooking time because it took a little longer to thicken but it might have just been my stove. Read More

Based on review, I only uses 1/2 cup sugar and a drop of lemon, buts it’s still way too sweet and hides the berry taste. Read More
