Vegan Pumpkin Protein Bars (No Protein Powder, 12g Protein)

Learn how to make 5 ingredient vegan pumpkin protein bars, with no protein powder! Sturdy and delicious, they have 12 grams protein & 161 calories each, and are vegan, grain-free & oil-free.

Grain-Free Vegan Pumpkin Protein Bars

It may be January, but I am absolutely not done with pumpkin. If you’re anything like me, you probably still have a can or two (or five) lingering from the holidays—and this is exactly the kind of recipe that makes that little stash feel like a very good idea. Even better, this is the time of year when you can often scoop up extra cans at a discount. Enter these pumpkin protein bars: cozy, lightly sweet, and secretly very hardworking.

These DIY protein bars are made with an unexpected but wonderfully practical ingredient: TVP (texturized vegetable protein). It’s inexpensive, shelf-stable, and once you get to know it, kind of a superhero in the high-protein, budget-friendly department. In these bars, it delivers a seriously satisfying nutrition profile—about 12 grams of protein and 7 grams of fiber per bar—without the addition of high-priced protein powders.

The bars are a breeze to make: no fuss, and only one bowl. They make great post-workout or on-the-go fitness snacks, but they also hit that “I want something sweet and comforting” note thanks to the maple syrup and spices. Plus, they check a lot of happy boxes: vegan, oil-free, gluten-free, and grain-free.

Practical, cozy, and a little bit indulgent—proof that pumpkin season can be whenever we want it to be.

Ingredients for 5-Ingredient Pumpkin Protein Bars

The exact amounts of each ingredient are indicated in the recipe card at the end of the post. Toggle between US Customary (volume) and Metric (weights) for preferred measurement option.

• TVP – Texturized Vegetable Protein (TVP) is a plant-based protein product made from defatted soy flour, a byproduct of soybean oil production. Most people are familiar with TVP when it is rehydrated (soaked in water or broth) and used as a meat substitute. However, I am experimenting with brand new ways to use it. When it is used dry, it is light and crispy, and entirely neutral in flavor. See my TVP buying tips, below.
• Maple syrup – maple syrup adds sweetness to the pumpkin bars while also adding moisture, which helps to soften the TVP and bind the ingredients into bars. I have alternatives for the maple syrup in the recipe notes below, and in the recipe card.
• Pumpkin purée— I use canned, unsweetened pumpkin purée. It is one of my year-round pantry staples. Double check that you are buying unsweetened purée, not pumpkin pie filling (the latter has added sweetener, salt and spices).
• Flaxseed meal–flax is well known for its fiber benefits, but it is also a good source of some protein. A quarter cup of flaxseed meal boasts 6 grams of protein! I prefer golden flaxseed meal in these bars (it has a slightly lighter flavor), but dark flaxseed meal works just as well.
• Pumpkin pie spice–if you do not have ready-to-use pumpkin pie spice, use an equal amount of cinnamon, or follow my DIY pumpkin pie spice instructions in the recipe card.

Guidelines for Buying TVP (Texturized Vegetable Protein)

1. Check the ingredient list: The only ingredient should be defatted soy flour. Avoid products with added flavorings, colorings, preservatives, or oils.
2. Look for non-GMO certification: Choose TVP that is labeled Non-GMO or carries a Non-GMO Project Verified seal. This ensures it’s made from soybeans not genetically modified.
3. Opt for organic: Organic certification guarantees the soybeans were grown without synthetic pesticides or herbicides, adding another layer of quality assurance.
4. Inspect packaging carefully: TVP should be sold in a sealed, airtight bag or container. Avoid damaged or poorly sealed packaging, as TVP absorbs odors and moisture easily.
5. Check freshness: When you open the package, TVP should have no noticeable smell. A stale, bean-y, or rancid odor is a sign of poor quality or old product.
6. Buy from trusted brands or suppliers: Select reputable companies with clear labeling and quality-control practices. Health food stores and natural food brands often carry purer options.
7. Check the texture and color: High-quality TVP should be light beige with a light, flaky texture (not hard pebbles). Discoloration may signal improper storage or age.
8. Buy in reasonable quantities: TVP is shelf-stable, but for maximum freshness, buy only what you will use within a few months.
9. Store properly after opening: Transfer TVP to an airtight glass jar or freezer bag. Keep in a cool, dark place (or freeze for long-term storage) to prevent odors or moisture from seeping in.
10. Avoid instant-flavored versions: Some TVP products are pre-seasoned for convenience, but they contain additives (such as caramel coloring). Always double-check labeling if you want pure, unflavored TVP.

Step by Step Instructions

Note that the complete directions are also in the recipe card below.

Step One: Do Not Add Water to TVP

A reminder: do not soak the TVP in water, as you would do in most TVP recipes. The TVP is used as a dry ingredient here, much like rolled oats.

Step Two: Preheat Oven & Prepare Pan

Line an 8-inch (20 cm) square baking dish with parchment paper or foil (for easy removal of the bars, and easy cleanup). Preheat the oven to 350F (180C).

Step Three: Combine Wet Ingredients

In a large mixing bowl whisk the pumpkin puree and maple syrup until blended and smooth.

Step Four: Add Dry Ingredients

Add the TVP, flaxseed meal, pumpkin pie spice, and optional salt to the bowl. Stir until completely combined and all of the TVP is coated.

You can stir in extras at this point (e.g., dried fruit, seeds, nuts or chocolate chips), or wait and press them into the top of the bars before baking.

Step Five: Spread Into Pan

Scrape all of the TVP bar mixture into the prepared baking pan. Use a spatula to spread and smooth the mixture in an even layer.

If desired, press optional ingredients (e.g., chopped dried fruit, nuts,, seeds or chocolate chips) into the surface of the bars.

Step Six: Bake

Bake in the preheated oven 25 to 30 minutes until the surface appears dry and the edges are slightly browned.

Step Seven: Cool & Cut Bars

Cool completely in the pan before removing to a cutting board and cutting into 9 big squares.

Storage for Vegan Pumpkin Protein Bars

Store the vegan pumpkin protein bars in an airtight container in the refrigerator for one week, or the freezer for up to six months.

Taste & Texture

The TVP pumpkin protein bars taste like soft pumpkin cookies, similar to ones made with oats and wheat flour. TVP has no flavor, so the flavor of pumpkin and spice shines through. They are lightly sweet from the maple syrup, but yu can make them sweeter with the addition of toppings or stir-ins, such as dried fruit or chocolate chips.

Flaxseed meal keeps the bars firm and sturdy–no crumbling! Pack them in your lunch bag or gym bag without fear of crumbling.

Substitutions

• Pumpkin Alternatives: Use an equal amount of mashed sweet potato purée in place of the pumpkin purée. Note: make sure the sweet potato is very soft and moist, not starchy. I recommend puree made from roasted sweet potatoes for the best texture and flavor. You can also used canned, unsweetened sweet potato puree, if you can find it.
• Maple syrup alternatives: Use an equal amount of agave nectar or brown rice syrup in place of the maple syrup. If you do not follow a vegan diet, you can also use an equal amount of honey. 

Variations for the High Protein Pumpkin Bars

• Dried Fruit: Add up to 1/2 cup of chopped dried fruit, such as raisins, dried apricots, dried cherries, dried cranberries, dried blueberries, or dried figs to the TVP mixture, or sprinkle on top of the pumpkin layer before baking.
• Nuts or Seeds: Add up to 1/2 cup chopped nuts or seeds, such as walnuts, pecans, peanuts, almonds, pepitas, or sunflower seeds to the TVP mixture, or sprinkle on top of the pumpkin layer before baking.
• Chocolate: Add up to 1/2 cup of dark chocolate chips or chopped chocolate to the TVP mixture, or sprinkle on top of the pumpkin layer before baking.
• Vanilla extract: Add an extra boost of flavor by stirring 1 to 2 teaspoons of vanilla extract into the pumpkin maple mixture.

Frequently Asked Questions (FAQ)

• I do not have an 8-inch square baking pan. Can I use a 9-Inch (22.5 cm) pan? Yes! The bars will be a little bit thinner, so begin checking for doneness after 22 minutes.
• How do I make my own pumpkin pie spice? Combine 1 teaspoon cinnamon, 1/2 teaspoon ground ginger, 1/4 teaspoon allspice, 1/8 teaspoon nutmeg and 1/8 teaspoon cloves. This yields the two teaspoons of spice needed in the recipe.
