The finished bars are portable and hold their shape well, so they’re ideal for holiday dessert tables or casual gatherings.

Ingredients & Substitutions

• Gluten-Free Flour Blend: Use a 1:1 gluten-free flour blend formulated for baking and already containing a binder such as xanthan gum. Popular blends work well—choose one you trust.
• Pumpkin Puree: Use pure canned pumpkin puree, not pumpkin pie filling, which contains added sugar and spices and will change the texture and flavor.
• Cream Cheese: Standard cream cheese is naturally gluten-free; if you need dairy-free, choose a dairy-free cream cheese alternative labeled gluten-free.
• Sugars & Vanilla: Both brown sugar and granulated sugar are gluten-free; use pure vanilla extract for best flavor.
• Spices: Pumpkin pie spice and cinnamon are gluten-free ingredients—double-check pre-mixed blends for any added fillers if you have strict allergen concerns.

*See the recipe card below for full ingredient amounts and measurements.

Dairy-Free Substitutions

• Cake: Replace butter with a neutral oil (canola, vegetable, or melted coconut oil) or a vegan buttery stick like Earth Balance.
• Frosting: Use a dairy-free cream cheese brand and dairy-free butter. If you prefer a simpler option, a store-bought gluten-free, dairy-free canned frosting can be used—just check labels carefully.

Equipment

• A shallow-rimmed nonstick metal pan or jelly roll pan works best.
• Measure your pan to confirm the size: this recipe fits a 9×13-inch or 10×15-inch pan. A standard 9x13x2-inch cake pan will also work.
• If you want a larger sheet, double the recipe and use a 13×18-inch half sheet pan.
• You can mix by hand, with a hand mixer, or with a stand mixer—choose the method you prefer.

How to Make Gluten-Free Pumpkin Squares

Part 1: Make the Cake

1. Whisk the dry ingredients—gluten-free flour blend, baking powder, baking soda, pumpkin pie spice, cinnamon, and salt—in a small bowl and set aside.
2. Cream the softened butter (or oil) with granulated and brown sugar in a large mixing bowl until light and fluffy.
3. Add the canned pumpkin, eggs, and vanilla, mixing until smooth. Gradually fold in the dry ingredients until evenly combined, scraping the sides of the bowl as needed.
4. Spread the batter into a prepared, greased pan and bake according to the recipe card below. Cool the cake completely before frosting.

Part 2: Prepare the Icing

5. Cream softened cream cheese and softened butter together until smooth and lump-free.
6. Add vanilla, then blend in powdered sugar a little at a time until the frosting reaches a thick but spreadable consistency.
7. Spread the frosting over the fully cooled cake and, if desired, garnish with gluten-free sprinkles.

Make Ahead, Storage, & Serving

• Make Ahead: The bars can be made a day in advance. Keep refrigerated until serving to maintain frosting texture.
• Storage: Refrigerate the frosted cake covered tightly; it will stay fresh for several days. The unfrosted sheet can sit at room temperature briefly but refrigeration is recommended for longer storage.
• Freezing: Individually wrap slices and store in an airtight container for longer storage. Thaw in the refrigerator or at room temperature; note that microwaving will soften the frosting.
• Serve: These bars are delicious chilled or at room temperature—choose based on personal preference and the setting.

Top Recipe Tips!

• Bring ingredients to room temperature before mixing for the best texture and even blending.
• Measure flour using the spoon-and-level method or, ideally, weigh it for accuracy—do not scoop directly from the bag or container.
• Double-check your pan size. This recipe yields a thinner sheet than many pumpkin-bar recipes, so correct pan dimensions matter.
• Allow the cake to cool completely top to bottom before frosting to prevent a runny topping.
• If using dairy-free frosting ingredients, you may need a little extra powdered sugar to reach the desired consistency.
• You may have leftover canned pumpkin; store it airtight in the refrigerator for 1–2 weeks or freeze for later use. Leftover pumpkin is great in lattes, waffles, oatmeal, or other baked goods.
