Jessie's recipes inspire sugary-coated adventures in the kitchen. CakeSpy is a treat for the curious and kid at heart.

Don't be fooled by her whimsical illustrations of emotive cupcakes and cake slices—this cookbook is not for the faint of heart. With over-the-top recipes like Glazed Cinnamon Rolls Stuffed with Chocolate Chip Cookie Dough, Birthday Cake French Toast, S'moreos, and Deep-Fried Cupcakes on a Stick, this colorful, humorous, unapologetically excessive book promises insatiably sweet-toothed readers the ultimate sugar high.

In addition to her baking and blogging skills, the founder of Cakespy, Jessie Oleson, is also a talented illustrator, and has created a line of original artworkfeaturing such characters as Cuppie (the cupcake), Toastie, Pie Slice, and Doughnut.

Whimsy, sweetness and spice characterize Oleson's illustrations and recipes, and all of these things carry through clearly from her blog to her book.

Jessie Oleson's confectionary illustrations are absurdly adorable and sweetly subversive

The table of contents for CakeSpy Presents Sweet Treats for a Sugar-Filled Life reads like a fairly conventional baking-related cookbook...until you look at the actual recipes and realize that they appear to be conceived by someone in only the happiest of sugar-induced states. Which is precisely why you will be taken with this book...In all, it’s a trip in and out of an imaginative mixing bowl.

Oh, Jessie Oleson from Cakespy, I do so love your whimsical art. Now, this might seem weird to gluten-free readers. Why in heavens would I recommend a website that glorifies the cupcakes, that sings the praises of bakeries around the world, and brings an overwhelming sense of glee of all that is sweet and baked? Well, you might not want to click on the main website, if you are feeling too down about not eating gluten. (For those of us are who are more hardy, it’s difficult not to feel the enthusiasm in the photos and words).

Anything touched by the sweet, arch, clever 'Spy' in her humor-mode is bound to bring on a smile -- if not an outright laugh. And now she's written a cookbook to bring some more sugar-filled hilarity to our own home kitchens.

That Jessie Oleson is a woman of many talents—baker, writer, illustrator, businesswoman—is impressive. That this Seattle resident manages to make a full-time living by harnessing all those talents under an umbrella enterprise called CakeSpy is damned improbable.

Her work, a blend of charming and fey, is populated by anthropomorphic baked goods, chiefly a cupcake christened 'Cuppie.' She writes regularly about sweets, from delving seriously into the history of apple pie to creating wacky recipes like 'Cupcake-Stuffed Cupcakes' and 'Cadbury Crème Eggs Benedict.'
