Apple Pear Streusel Cake (gluten free, vegan, sugar free)

While reading my copy of The Yeast Connection Cookbook some time ago, I came across a recipe for "Magic Apple Pie".  I was intrigued - it was a crustless pie, sweetened with pureed pears.  I knew I had to try it some time.  I've had a hankering for a fruity dessert thing lately, and since I am having a few friends over tonight - the first social gathering at my new apartment! - I decided now is as good a time as any to try this whole magic apple pie thing out.  Instead of a pie pan, I put it in a square pan to make a cake, and whipped up a crunchy, lightly sweetened streusal topping to add to the top.  As it baked, and my home filled with the sweet smell of baking apples, I got a good feeling about it.
I couldn't resist sampling a bite before my friends arrived, and was totally pleased with the result! This cake is a little fragile, but has a good texture and amazing flavor. The combination of pears and apples is lovely - making the pureed pear sweetener is a litlte time consuming, but well worth the effort.  I used mesquite flour and a little allspice to achieve a spicy, warm flavor, but if you can tolerate cinnamon, go ahead and use that.   The streusal topping is crunchy and just a little sweet, and adds a nice touch. 
My friends really liked it, and thought it tasted great.  They were surprised that it didn't have any added sugar.  I like getting feedback from my gluten-eating, sugar-loving friends because I feel like I've lost my ability to be an impartial judge - I'm glad they are good sports and supportive of my baking endeavors.  We all agreed that while the cake was totally delicious, it would be awesome to add berries.   The cake is fairly moist and the apples are juicy, but overall, it is verging on the crumbly side, since brown rice flour tends to cook up a bit dry.  So, added berries would help add a nice, juicy twist - apple blackberry perhaps?  Or maybe use sliced pears instead of apples, and add blueberries.  Or sliced peaches and raspberries.  Or use only berries.  Or maybe rhubarb?  A handful of nuts or seeds thrown in would be delightful as well.  The combinations are endless, and I'll need to try this recipe again.  
Give a try exactly as it is, try using other fruit, or add nuts; either way, I think you'll be very happy!  This would make a great crumb cake for breakfast brunches or afternoon tea parties.  For something more dessert like,  serve up with a scoop of your favorite ice cream-like frozen dessert, or a dallop of whipped coconut milk or non-dairy yogurt - or the real stuff, if you're a dairy eater.
