Here’s the thing about making dessert in the summer. On the one hand, we want to take every opportunity we can to enjoy the season’s bounty, and make the most of those fresh-picked fruits from farmers’ markets, roadside stands, and local orchards and farms. On the other hand? They don’t call them the “lazy hazy days of summer” for nothing!

For a lot of us, we can’t quite get over the habit of taking a mental break during the months between the end of one school year and the beginning of another, even if it’s been years since we stepped into a classroom. So what does this relaxed state mean for learning new recipes? Just that we’re leaning toward creative takes on the classics, recipes that really let the ingredients shine— and toward ones that are really easy! You can’t do any better on all three criteria than with a dump cake!

This easy dessert takes a fruit filling – in this case, perfect summer peaches and blueberries – and just “dumps” cake mix on top of it for a treat that’s one part cake, one part cobbler, all parts tasty. And don’t worry— we’re not using boxed cake mix. Oh no. Every bit of this dish is homemade, and every bit is delicious. Check it out.
