WOW! Anyone who says they can taste the mayo must have put too much in! This was fantastic! We were cooped up in the house today, and hungry... I did a search for a fruit recipe that needed no milk, eggs or butter (I'm out of all 3!) and found this! I mixed together some frozen blueberries, blackberries and raspberries, used a little extra flour and turbinado sugar instead of white. I also added a dash of ground ginger to the topping- placed it all into a 9 inch pie plate. Turned out fantastic and my bf had no idea there was mayo in it- he loved it! Will def make this again, and I can't wait to put it all over vanilla ice cream! Thanks for the great recipe!

So good and so easy! Thanks for the recipe!

So easy and so good. I added approx 1-2 TBSP of brown sugar to the topping but otherwise made 'as is'

Wonderful, SOOOOOO EASY!

I didn't like the taste of the mayo. It was simple to make but the taste was off to me.

Horray!! This is fantazzzztic. I follwed it almost exactly except that i used a 1/4 c of brown sugar and the rest white sugar. I think next time I will just use brown, cuz i like to think its healthier for you!! Top this crisp with plain yougurt and its an awesome treat!!

Great recipe. I used Hellman's Light mayo and used 1/2 cup of sugar as well as 1 teasp. of cinnamon. This tasted wonderful and wasn't overly sweet. It takes about 10 minutes to putall the ingredients together. This one goes into my recipe book

Wow! Who knew that using the "secret ingredient" of mayo would make this dish so tasty! Thanks for sharing.

I divided this recipe in half..after I realized I only had 2 cups of blueberries. This is surprisingly delicious. I could not believe how good it was. Thx.

Made with Splenda rather than Sugar- came out perfectly! Tasted delicious, easy to make

This was awesome and so easy!!!

It was ok, but I probably won't make it again.

This blueberry crisp is excellent. I took another reviewer's suggestion to double the topping, and it was even better.

This stuff is great, very tasty. I followed the recipe exactly, except I had only light mayo and it came out great. Next I tried using whole wheat flour, extra blueberries, and a bit less sugar and it came out good, but not as great as the first time. If you're on a strict diet the healthier version is definitly edible but the original is definitly the best! Good, easy, very tasty recipe!

This was GREAT! The mayo is really an interesting ingredient but it crisps up better than butter. I used brown sugar instead of white, and tossed the blueberries with a bit of flour. I also mixed in 1 tsp of vanilla and 1 tsp of lemon extract in with the blueberries. This dish was eaten up very quickly!

Great recipe I added 1/4 cup of oatmeal, 1/8 more flour, 1/4 cup melted butter, pinch of cinnimon and nutmeg. perfect!

Really good and easy to make. Not as sweet as a dump cake, but very tasty!
