Gluten-Free Chocolate Cake with Raspberry Sauce

This luscious chocolate cake with raspberry sauce is a tender, never-dry dessert that pairs beautifully with a simple dusting of powdered sugar or a spoonful of bright raspberry sauce. It’s easy to bake, travels well, and consistently earns compliments whether served at a casual potluck or a family gathering. The recipe adapts well to gluten-free flour blends, which makes it a dependable choice for guests with dietary needs.

I originally found this cake on the back of an ingredient package and since then it has become a family favorite—my partner’s father requests it for holidays and get-togethers. While I often tweak package recipes as a starting point, this one remains nearly unchanged because it’s simply perfect as written. I have converted it to gluten-free with excellent results and include tips below to make that transition easy.

Baking is full of little surprises: once I began assembling the ingredients while I had just made a fresh gluten-free flour blend, I accidentally missed the sugar in the first mix. A quick taste of the leftover batter on the spatula saved the day—I realized the sugar had been omitted, added it in, and the cake turned out beautifully. Mistakes happen to everyone; the key is to pause, check the ingredient list, and rescue the batter when you can.

Because the cake bakes and cools in a 9×13-inch pan, it’s convenient to transport and serve. My favorite way to present it is with a shallow pool of raspberry sauce on the plate and a neat square of cake beside it, finished with a dusting of powdered sugar and a fresh mint sprig. If you prefer to make your own sauce, blend frozen raspberries with a little sugar and a splash of liquor if you like—the result is bright and intense. For a quick option, jarred raspberry sauce from the grocery aisle is an easy pantry backup.

Ingredients needed for Chocolate Cake with Raspberry Sauce:

Milk (or buttermilk), neutral oil or melted butter, eggs, vanilla
Granulated sugar
All-purpose flour or a gluten-free flour blend
Unsweetened cocoa powder, baking soda, baking powder, salt
Boiling water (or strong prepared coffee)
Raspberry sauce and powdered sugar for serving; fresh mint for garnish

PRO Tip:

Before you start mixing, arrange your ingredients where you can see them clearly. Place items on one side of the counter and, as you add each ingredient, move it to the other side. This simple habit prevents missing or doubling ingredients, especially when the kitchen gets busy or you’re distracted.

How to make Chocolate Cake with Raspberry Sauce:

Preheat the oven to 350°F (177°C) and set a rack in the center. Butter and lightly flour a 9×13-inch nonstick baking pan; if using a gluten-free flour, use a bit of that for dusting the pan.
Place one cup of water in a microwave-safe measuring cup and heat until boiling; leave it in the microwave while you assemble the rest.
In a separate cup, whisk together the milk (or buttermilk), oil, eggs, and vanilla. Set aside.
Combine all dry ingredients—sugar, flour (or gluten-free blend), cocoa, baking soda, baking powder, and salt—in the bowl of a stand mixer or a large mixing bowl. Mix on low until evenly blended with no lumps of dry ingredients visible.
With the mixer off, pour in the milk/oil mixture and start mixing on low. Increase to medium and beat for about 2 minutes. Scrape the bowl and beater(s) to incorporate any stuck bits.
With the mixer on the lowest speed, add the boiling water very slowly, about 1 tablespoon at a time, to avoid splashing. The batter will become very thin—this is expected. Scrape the bowl again to ensure everything is mixed.
Pour the batter into the prepared pan, tap the pan a few times to release air bubbles, and bake for 35–45 minutes, or until a toothpick inserted in the center comes out mostly clean.
Remove the cake from the oven and set it on a wire rack to cool completely in the pan. If you used gluten-free flour, allow the cake to cool fully before cutting to help it set. The cake may sink slightly in the center as it cools.
To serve, spoon 1–2 tablespoons of raspberry sauce onto each plate, add a square of cake, dust with powdered sugar through a fine sieve, and add a mint sprig for color.

PRO Tip:

When a recipe calls for several ingredients to be combined at once, pre-measure and mix those groups in small bowls. For this cake, whisk the dry ingredients together and combine the liquid ingredients separately so assembly is quick and smooth. This mise en place technique speeds up the process and reduces errors.

Recommended Tools:

Kitchen scale (handy for precise flour measurements)
9×13-inch baking pan
Microwave-safe measuring cup
Stand mixer or hand mixer
Wire cooling rack
Fine mesh sieve for dusting powdered sugar

Gluten-Free Tips:

To convert many baking recipes to gluten-free, a reliable starting point is to use a gluten-free flour blend weighed at about 120 grams per cup. If you use a commercial blend, whisk it well, spoon it lightly into a dry measuring cup until mounded, level it off, and weigh what remains to determine the weight that corresponds to one cup for that brand. Use that weight as your standard for consistent results. When coating your pan, use the same gluten-free flour so the surface and cake respond similarly.

All ingredients should be verified for gluten-free status based on current packaging and labeling; manufacturers can change formulations, so check labels if you have strict dietary requirements.

Notes:

This cake adapts well to different toppings—raspberry sauce, a simple glaze, or your favorite frosting all work. If you prefer a deeper chocolate flavor, substitute prepared strong coffee for boiling water. The recipe is forgiving: if an ingredient is overlooked, often you can add it before baking and the batter will still turn out well.
