Introduction
This pumpkin snack cake is built for people who want fall flavor without the fuss of frosting or multiple layers. It’s a single-bowl style cake baked in an 8-inch square pan, with canned pumpkin giving it a moist, tender crumb and a warm autumn color, while a touch of cocoa and cinnamon add depth without turning it into a full-on chocolate cake. What makes it stand out is the crunchy topping — a mix of chocolate chips, salted pumpkin seeds (or pepitas), and a sprinkle of sugar — which bakes right into the surface and gives every square a bit of salty-sweet crunch instead of a thick frosting. It comes together quickly, with just 15 minutes of prep and 25 minutes in the oven, making it an easy weeknight bake or a simple contribution to a fall gathering. If you’d rather have a sweeter, more traditional cake, the topping can be skipped in favor of your favorite frosting instead.
Ingredients
Cake
- ¼ cup butter, softened
- ¾ cup sugar
- 1 large egg, room temperature
- 1 cup all-purpose flour
- 1 tbsp baking cocoa
- ½ tsp baking soda
- ½ tsp ground cinnamon
- 1 cup canned pumpkin
Topping
- ½ cup semisweet chocolate chips
- ½ cup salted pumpkin seeds or pepitas
- 1 tbsp sugar
The canned pumpkin is doing double duty here — it adds moisture in place of extra butter or oil, and it’s also what keeps this cake dense and snackable rather than light and fluffy, closer in texture to a pumpkin brownie than a layer cake. The salted pumpkin seeds in the topping are a nice contrast to the sweetness of the cake itself, so it’s worth using salted rather than raw seeds if you have the choice.
How to Make It
Step 1 – Cream the butter and sugar. Preheat your oven to 350°F. In a large bowl, cream together the softened butter and sugar until light and well combined. Beat in the egg until fully incorporated.
Step 2 – Add the dry ingredients. In a separate bowl, combine the flour, cocoa, baking soda, and cinnamon. Gradually add this mixture into the creamed butter mixture, stirring until well combined and no dry streaks remain.
Step 3 – Fold in the pumpkin. Stir in the canned pumpkin until the batter is smooth and evenly colored throughout.
Step 4 – Assemble and top. Pour the batter into a greased 8-inch square baking pan, spreading it evenly to the edges. In a small bowl, combine the chocolate chips, pumpkin seeds (or pepitas), and the tablespoon of sugar, then sprinkle this mixture evenly over the top of the batter.
Step 5 – Bake and cool. Bake for about 25 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool in the pan on a wire rack before slicing into 16 squares.
A Note on Diabetic Suitability
As with most traditional snack cakes, this recipe uses regular sugar and all-purpose flour, so it isn’t formulated specifically as a diabetic-friendly dessert. Each serving carries 22g of total carbohydrate and 14g of sugar, which is on the higher side for anyone closely tracking blood glucose. That said, the recipe’s own diabetic exchange guidance — 1½ starch and 1½ fat per piece — indicates it can still be worked into a diabetic meal plan occasionally, especially in a smaller portion and balanced against other carbs eaten that day. If you wanted to make this cake more diabetic-friendly, the most useful changes would be replacing the sugar in both the cake and topping with a granulated sugar substitute, and using a sugar-free chocolate chip in the topping instead of the semisweet variety. The pumpkin itself is a helpful base either way, since it contributes fiber and nutrients without adding much sugar on its own — the sweetness here comes mainly from the added sugar rather than the pumpkin. As always, it’s worth checking with a doctor or dietitian about how a cake like this fits into your individual plan, particularly around portion size and timing.

How to Store
Once fully cooled, cover the pan tightly or transfer the squares to an airtight container and store at room temperature for up to 2 days, or in the refrigerator for up to a week if you’d like it to keep a bit longer — the pumpkin helps it stay moist either way. This cake also freezes well: wrap individual pieces in plastic wrap and place them in a freezer-safe bag or container, where they’ll keep for up to 3 months. Thaw at room temperature for an hour or two, or overnight in the refrigerator, before serving. Because the topping is baked directly onto the batter rather than added afterward like a frosting, it holds up well through storage and freezing without becoming messy or separating.
