High Protein Pumpkin Muffins are soft, warmly spiced muffins made with pumpkin puree and protein-rich Greek yogurt for a satisfying breakfast or snack. They have a tender, moist crumb with plenty of pumpkin flavor, while a little maple syrup adds sweetness without making the muffins overly sugary.

This version comes together in one bowl and uses simple pantry ingredients. The muffins are especially convenient for meal prep because they keep well in the refrigerator and can be frozen for longer storage.

Why This Recipe Works

Pumpkin puree adds moisture to the batter, helping the muffins stay tender without needing a large amount of oil.
Greek yogurt provides protein and structure while contributing a creamy texture to the crumb.
Oat flour gives the muffins a soft, hearty texture and pairs naturally with pumpkin and warm spices.
Maple syrup provides balanced sweetness that complements the pumpkin without overpowering its flavor.
A moderate oven temperature encourages even baking so the centers cook through before the tops become too dark.

Equipment Needed

12-cup standard muffin pan
Paper muffin liners
Large mixing bowl

Ingredients List

Muffins

1 cup pumpkin puree — 225 g — use plain canned pumpkin, not pumpkin pie filling

2 tablespoons melted unsalted butter — 28 g — slightly cooled
1 teaspoon vanilla extract — 5 mL
1 1/2 cups oat flour — 150 g — spooned and leveled
1/2 cup vanilla protein powder — about 45 g — use a protein powder suitable for baking
1 teaspoon baking powder — 4 g
1/2 teaspoon baking soda — 2.5 g
1 1/2 teaspoons ground cinnamon — 4 g
1/2 teaspoon ground ginger — 1 g
1/4 teaspoon ground nutmeg — 0.5 g

Ingredient Notes and Substitutions

Pumpkin puree: Pumpkin provides moisture, color, and the characteristic flavor of the muffins. Use plain pumpkin puree rather than pumpkin pie filling. Mashed butternut squash can work as a substitute, although the flavor will be slightly less pumpkin-forward.
Greek yogurt: Greek yogurt adds moisture and protein while helping create a tender crumb. Plain skyr can be substituted, though the muffins may be slightly firmer.
Protein powder: Vanilla protein powder contributes protein, sweetness, and structure. Different powders absorb liquid differently, so the batter should be thick but scoopable. A plain protein powder can be used with a little extra vanilla if needed.
Oat flour: Oat flour gives the muffins a soft, lightly hearty texture. Finely ground whole-wheat flour can replace it, but the muffins will be somewhat denser and more substantial.
Maple syrup: Maple syrup sweetens the batter and adds a mild caramel-like flavor. Honey can replace it in the same quantity, producing a slightly stronger sweetness and flavor.

Step-by-Step Instructions

Step 1: Prepare the oven and pan.

Heat the oven to 350°F (175°C). Line a standard 12-cup muffin pan with paper liners. Lightly grease the liners if desired for easier release.

Step 2: Mix the wet ingredients.

In a large bowl, whisk together the pumpkin puree, Greek yogurt, eggs, maple syrup, melted butter, and vanilla extract until smooth. The mixture should look creamy and evenly orange with no visible streaks of yogurt or egg.

Step 3: Combine the dry ingredients.

Add the oat flour, protein powder, baking powder, baking soda, cinnamon, ginger, nutmeg, and kosher salt to the bowl. Whisk or stir gently until the dry ingredients are evenly distributed.

Step 4: Finish the batter.

Fold the dry ingredients into the pumpkin mixture with a rubber spatula just until no dry patches remain. The batter should be thick and scoopable. If it seems unusually stiff, let it stand for 1–2 minutes; oat flour and protein powder will continue absorbing moisture.

Step 5: Fill the muffin cups.

Divide the batter evenly among the 12 prepared muffin cups, filling each about three-quarters full. Sprinkle the tops with the pumpkin seeds if using.

Step 6: Bake.

Bake at 350°F (175°C) for 18–22 minutes, rotating the pan once if your oven browns unevenly. The tops should look set and lightly rounded, and a toothpick inserted into the center should come out with a few moist crumbs rather than wet batter.

Step 7: Check for doneness.

If the centers still look wet after 18 minutes, continue baking for 2–4 minutes. Avoid overbaking, since protein powder can make muffins dry when cooked too long.

Step 8: Cool.

Let the muffins cool in the pan for 5 minutes, then transfer them to a wire rack. Cool for another 5 minutes before serving. The crumb will become more stable as the muffins cool.

Tips for Success

Measure oat flour by weight when possible because packed flour can make the batter too dry.
Avoid overmixing once the flour is added; excessive mixing can make the muffins dense.
Protein powders vary significantly in absorbency. If your batter is much thicker than a typical muffin batter, check the protein powder's formulation before adding more liquid.
Do not use pumpkin pie filling in place of pumpkin puree because it already contains sugar and spices.
Let the muffins cool before storing them. Trapping warm muffins in a container can create condensation and make the tops sticky.

Storage, Freezing, and Make-Ahead Instructions

Store completely cooled muffins in an airtight container in the refrigerator for up to 5 days. Place parchment or a paper towel between layers if condensation is an issue.
For longer storage, freeze the cooled muffins in a freezer-safe bag or airtight container for up to 3 months. Freeze them in a single layer until firm, then transfer them to the container to prevent sticking.
For make-ahead meal prep, bake the muffins up to 5 days in advance and refrigerate them once fully cooled. Frozen muffins can be thawed overnight in the refrigerator or at room temperature for several hours.

FAQ

Can I use a different protein powder?

Yes. Vanilla whey, whey-casein blends, and some plant-based protein powders can work, but they do not absorb liquid identically. The finished batter should be thick and scoopable rather than dry or crumbly.

Can I use whole-wheat flour instead of oat flour?

Yes. Replace the oat flour with 1 1/2 cups (180 g) finely ground whole-wheat flour. The muffins will have a slightly denser texture and more pronounced wheat flavor.

How do I know when the muffins are done?

The tops should be set and lightly rounded, and a toothpick inserted into the center should come out with a few moist crumbs but no wet batter. Avoid baking significantly past this point because the protein powder can contribute to dryness.

Can I make these muffins without pumpkin seeds?

Absolutely. The pumpkin seeds are an optional topping and do not affect the muffin batter.

Can I freeze high protein pumpkin muffins?

Yes. Cool them completely before freezing in an airtight freezer-safe container or bag for up to 3 months. Thaw at room temperature or overnight in the refrigerator.
