Irresistible German Chocolate Cookie Bars

Here are my favorite German chocolate cookie bars, with a chewy cookie base, a gooey coconut pecan filling, and a drizzle of chocolate on top.

These bars are always the first to disappear at bake sales and potlucks. I like to make a double batch and freeze half for when we need a quick dessert. They’re so much easier than making a traditional German chocolate cake, but just as good!

What Kind of Cake Mix Should I Use?

For these cookie bars, you’ll want to grab a standard devil’s food cake mix or German chocolate cake mix from the baking aisle. The key thing to remember is to avoid the cake mixes that have pudding already added in – those will throw off the texture and make your bars too dense. Most regular cake mixes are around 15-16 ounces, and that’s exactly what you need here. If you can find German chocolate cake mix specifically, that’s a great choice since it’ll give you that classic flavor, but devil’s food works just as well and is usually easier to find at most grocery stores.

Options for Substitutions

These cookie bars are pretty forgiving, so here are some swaps you can make:

• Devil’s food cake mix: If you can’t find devil’s food cake mix without pudding, German chocolate cake mix works great too. Regular chocolate cake mix will also do the job, though the flavor will be slightly different.
• Butter: You can use coconut oil or vegetable oil instead of butter. The texture will be slightly different, but the bars will still turn out tasty.
• Pecans: Walnuts are a solid substitute for pecans, or you can use almonds if that’s what you have. Not a nut fan? Just leave them out or add extra coconut.
• Shredded coconut: Both sweetened and unsweetened coconut work fine here. If you’re not into coconut, you can reduce the amount or skip it entirely, though it is a key part of that German chocolate flavor.
• Milk chocolate chips: Semi-sweet or dark chocolate chips work just as well. You could also chop up a chocolate bar if you don’t have chips on hand.
• Sweetened condensed milk: Regular or fat-free sweetened condensed milk both work perfectly. Don’t substitute with evaporated milk though – they’re completely different products and won’t give you the same results.

Watch Out for These Mistakes While Baking

The biggest mistake with these cookie bars is overbaking them, which turns a chewy, fudgy treat into a dry, crumbly disappointment – pull them from the oven when the edges are set but the center still looks slightly underdone, as they’ll continue cooking while cooling in the pan.

Make sure to press your cake mix crust firmly and evenly into the pan before adding the toppings, otherwise you’ll end up with gaps and an uneven base that doesn’t hold together when you cut the bars.

When mixing your sweetened condensed milk layer, whisk the egg in completely to avoid any eggy pockets, and spread the pecans and coconut evenly across the surface so every bite gets that classic German chocolate flavor.

Finally, resist the urge to cut these bars right away – letting them cool completely (or even chilling them in the fridge for an hour) makes slicing much cleaner and prevents the gooey topping from sliding off.

What to Serve With German Chocolate Cookie Bars?

These rich, chocolatey bars are pretty indulgent on their own, so I like to keep things simple when serving them. A cold glass of milk is always a winner, or if you’re serving them to adults, a hot cup of coffee really brings out the chocolate and coconut flavors. You could also scoop some vanilla ice cream on top while the bars are still warm for an extra special dessert. If you’re putting together a dessert spread, these pair nicely with fresh berries or a fruit salad to balance out all that sweetness.

Storage Instructions

Store: Keep these cookie bars in an airtight container at room temperature for up to 3 days, or in the fridge for up to a week. I actually prefer them cold from the fridge because the texture gets a bit fudgier and the flavors meld together even better.

Freeze: These bars are perfect for freezing! Cut them into individual portions, wrap each one in plastic wrap, and store in a freezer bag for up to 3 months. They thaw quickly on the counter, or you can eat them straight from the freezer for a cool treat.

Make Ahead: You can bake these a day or two in advance, which actually makes them easier to cut into clean bars. Just let them cool completely, cover tightly with foil, and store at room temperature until you’re ready to serve.

Ingredients

For the crust:

• 1 box devil’s food cake mix (not pudding-included)
• 1 large egg
• 1/2 cup butter (melted and cooled slightly)

For the topping:

• 1 large egg
• 1 can sweetened condensed milk (I use Carnation for consistency)
• 1/2 cup milk chocolate chips
• 1 cup chopped pecans (toasted for enhanced flavor)
• 1 tsp vanilla extract
• 1 cup shredded coconut

Step 1: Preheat the Oven and Prepare Baking Pan

Preheat your oven to 350°F (175°C).

Grease a 9×13 inch baking pan using either non-stick cooking spray, melted butter, or your preferred method to prevent the bars from sticking.

Step 2: Make the Cake Crust

• 1 box devil’s food or German chocolate cake mix (not pudding-included)
• 1/2 cup butter, melted
• 1 large egg

In a medium mixing bowl, combine the devil’s food or German chocolate cake mix (make sure it’s not the pudding-included type), melted butter, and one large egg.

Mix until fully combined into a uniform dough.

Press this mixture evenly into the bottom of your prepared pan, making sure it doesn’t go up the sides.

Step 3: Bake the Crust

Bake the pressed crust in the preheated oven for 7 minutes.

It will not look fully cooked—this is expected at this stage.

Remove the pan from the oven and set aside.

I always like to slightly underbake the crust so the final bars are chewy and moist.

Step 4: Prepare the Topping Mixture

• 1 can (14 oz) sweetened condensed milk (fat free is fine)
• 1 tsp vanilla extract
• 1 large egg
• 1 cup chopped pecans
• 1 cup shredded coconut

While the crust is baking, in a separate bowl stir together the sweetened condensed milk, vanilla extract, one large egg, chopped pecans, and shredded coconut until fully combined.

This mixture will be poured over the crust.

Step 5: Assemble the Bars

• topping mixture from Step 4
• crust from Step 3
• 1/2 cup milk chocolate chips

Pour the topping mixture evenly over the warm, partially baked crust.

Sprinkle the milk chocolate chips uniformly across the surface.

Step 6: Bake and Cool the Bars

Return the pan to the oven and bake for 24-30 minutes, or until the top is a light golden brown.

Once finished, remove from the oven and let cool completely in the pan before cutting into squares.

For a cleaner slice, I like to chill the bars in the fridge for about an hour after cooling.
