I too used strawberries instead of raspeberries because they are a lot cheaper. I love the idea of using cookie dough for a 'crust'! I was able to get by without using a mixer to make the cream chese mixture. I just made sure the cream cheese was extra soft. The zest of 1/2 an orange was enough for me. My only complaint is that I didn't have enough cream cheese filling to fill all 32 tarts! Next time I'll use 12oz cream cheese. They look great though!
I love this recipe. I've been making this for over a year now and they taste like miniature cheesecakes. I omitted the zest of orange and used strawberries instead of raspberries. Yum!
