Peach Dump Cake

by Victor @ Taste of Artisan

Do you get pleasantly surprised every now and again at how good some of the most simple recipes turn out? Peach dump cake is one of those surprise recipes in my book, for sure. I am a picky eater and have a tendency to think that more complex and advanced recipes result in more refined and complex flavors, rightly or wrongly.  Well, this peach dump cake recipe showed me that it ain’t always the case. Like many home cooks out there, I struggled with this simple peach dump cake initially. After some trial and error, it works 100% of the time for me now.

This recipe has become so popular in our family that it’s now a regular. The best part is that you can use any fruit or berries with this recipe, and they can be fresh, canned or frozen.

Preparing the peaches

For a smoother texture of the filling I peel the peaches, which should not be hard when peaches are fully ripe. If they are not ripe enough, a quick blanching will solve the problem. Just carefully immerse the peaches in boiling water for about 30-40 seconds, remove and give them a cold shower. Now the skin will come right off.

The cake mix – commercial vs. homemade

Most every dump cake recipe that I’ve seen out there called for a store-bought cake mix. This technically makes sense. A dump cake is supposed to be easy, hence the name. Who wants to make own cake mix for the dump cake? This kind of defeats the whole purpose, right? Well, not exactly.

A cake mix is just a combination of four basic ingredients: flour, sugar, baking powder and salt. Every home cook will mostly likely have them readily available in the kitchen and it takes minutes to find and mix them together.

As well, in a homemade cake mix you won’t be getting all the chemicals, wonders of modern food industry, and the resulting off flavors. The Kitchn wrote an interesting article on commercial vs. homemade cake mixes and concluded that there is virtually no time saving when using commercial cake mixes and that the homemade cake mix wins in taste department hands down.

Making the peach dump cake work

The idea of dumping a few basic ingredients into a baking dish and getting a beautiful peach dump cake half an hour later is so appealing. This explains the multitude of dump cake recipes online. Do they work? I hate to break it to you, but sometimes they do, sometimes they don’t. I’ve had the hardest time making this peach dump cake work. I’ve had more success making my first mille-feuille than this supposedly super easy dump cake.

What doesn’t work?

For some unknown reason most peach dump cake recipes – and other dump cakes out there – emphasize that you are not to stir the ingredients. Why? Beats me. Will stirring make the effort less easy? Absolutely not. It only takes 15 seconds or so. But not stirring the ingredients is the source of the problem, I think.

As I said before, my initial attempts to make a peach dump cake kind of worked some time, but most of the time they did not. I tried close to a dozen different recipes. I tried to stick true to the process – so no mixing. This almost always created a problem – the cake mix would not get fully hydrated during baking and I would end up with a cake that has lumps of dry flour mix. Sometimes I would end up with the whole surface covered with toasted dry flour.

To fix the problem I covered the surface of the unbaked cake with butter pats, which was suggested by a couple of recipes I found online. The crust came out perfectly baked where I had butter pats, with patches of dry flour in between. Darn! I rescued it by covering dry flour patches with more butter pats and baking a bit longer.

Is the butter not covering the entire surface of the mix the problem? The next time I cut butter sticks very thinly to ensure I can cover the entire surface with the same amount of butter. That trick did barely anything to address the problem. The layer of butter too thin? Maybe. But I don’t want too much butter in my dump cake.

Then I noticed that where flour mix touched the liquid in the baking dish the mix got hydrated and perfectly cooked. So I increased the amount of peach juice. That did not help much with the flour clumps and resulted in a liquid-y mess at the bottom of the cake. Not a good solution.

I also tried cutting the butter into the cake mix, like you would when making pie dough. I thought it would help, but it absolutely did not. The entire surface of the cake ended being dry, toasted flour. Again, I had to rescue it. I mixed the dry flour with the rest of the ingredients and baked for another 15 minutes. I came out looking messy, but still tasted delicious. I mean, here’s what was left of it 8 minutes after I took it out of the oven.

So, why did it work some times? I have no idea. Nor do I care much. If it doesn’t work every time, unless you as a chef mess up, it’s a bad recipe.

What does work?

When making a dump cake with fresh peaches or other fresh fruit it’s important to make sure that the flower mix  gets properly hydrated and cooked during the bake to avoid dry flour clumps, we know that already. So, how do we get that? Obviously, dumping a bunch of dry cake mix over fresh peaches and sparsely covering the mix with butter pats doesn’t work too well.

Through some experimentation I found that you need several things in place in order to make your peach dump cake work every time. Mix the ingredients then dump!!! That’s the only way that worked for me 100% of the time.

If you do know of a way to not mix and get a perfectly cooked peach dump cake every single time, let me know. Otherwise here is how to make the best peach dump cake and it works 100% every time.

  1. Mix the ingredients
  2. Reduce the amount of cake mix. Less cake mix means better hydration during baking. And fewer calories needed to be burned in the gym later. Most of the recipes I’ve seen call for about 4 cups of flour (one box of yellow cake mix). That’s insane. Two cups are plenty enough.
  3. With fresh peaches you need additional liquid. You see, canned peaches, often used to make peach dump cakes, come with a fair amount of liquid, which you don’t discard and use in the cake, and that liquid is what helps moisten the cake mix and ensure proper cooking. As a result, when using fresh peaches you need to add a little bit of liquid. What works for me is adding about 1/2 cup of peach juice, or mango juice, or any other juice I have on hand.
