Jello cakes are the best. It’s an old-school technique that combines a flavored gelatin mix with the usual cake batter to produce a cake with a delightfully moist texture. This lemony version is bursting with sunny citrus flavor. As you’d expect from a Jello cake, the crumb is beautifully tender. To top it off, the recipe is outrageously simple to make.
Besides including flavored gelatin in the batter, this recipe employs another time-tested technique. Immediately after the cake is baked, you’ll poke holes all over the top and then drizzle a sweet, vanilla-scented glaze over the top. The glaze will run into the holes and soak into the cake giving it even more flavor and moistness.
The best part? Only 10 mins of prep!
