Can you substitute peanut butter for maple syrup?

When it comes to substituting ingredients in recipes, many home cooks wonder if they can use peanut butter instead of maple syrup. While they have some similarities, there are important differences between these two ingredients that impact how well one can stand in for the other.

Quick Answer

In most cases, peanut butter is not a good direct substitute for maple syrup. Maple syrup provides a unique flavor as well as moisture and sweetness, which peanut butter cannot fully replicate. However, in some recipes, peanut butter can be used in smaller quantities as part of a maple syrup replacement by combining it with other ingredients to create a similar texture and sweetness.

Maple Syrup Overview

Maple syrup is made from the sap of maple trees. It goes through an extensive process of collection, filtering, boiling, and grading before it makes it to the grocery store shelf. Pure maple syrup contains only maple sap and water.

Maple syrup is valued for its unique maple taste, as well as its moisture, sweetness, and uses in cooking and baking. Here are some key characteristics of maple syrup:

  • Sweetness – Maple syrup grades range from mild to very dark and robust. The darker grades are less sweet due to more caramelization.
  • Moisture – Maple syrup contains about 60% sugar and 40% water, giving it a syrupy texture.
  • Flavor – Maple syrup has a distinctive maple taste that varies based on grade.
  • Baking Utility – Maple syrup can add moisture, tenderness, and flavor to baked goods.
  • Culinary Uses – Maple syrup is used as a topping for pancakes and waffles, and as an ingredient in sauces, marinades, candies, and more sweet and savory recipes.

Peanut Butter Overview

Peanut butter is made from roasted peanuts that are ground into a paste. It typically contains peanuts, oil, and sometimes salt or other flavorings. Here are some key characteristics of peanut butter:

  • Fat content – Peanut butter gets its creamy, thick texture from peanut oils. It contains about 50% fat from the nuts. This makes it denser and richer than maple syrup.
  • Sweetness – Peanut butter has a mildly sweet flavor from the peanuts and added sugar if present. But it is far less sweet than most maple syrup grades.
  • Moisture – Peanut butter contains very little moisture, giving it a thick, spreadable consistency.
  • Flavor – Roasted peanuts give peanut butter a distinctive nutty, earthy flavor.
  • Baking Utility – Peanut butter can add flavor, moisture, and structure to baked goods.
  • Culinary uses – Peanut butter is most often used as a spread, but also as an ingredient in sauces, baked goods, candies, and Asian cuisine.

Key Differences

When comparing maple syrup and peanut butter, the most significant differences are:

  • Sweetness – Maple syrup is primarily composed of sugar dissolved in water, making it very sweet. Peanut butter has little inherent sweetness.
  • Moisture content – Maple syrup is smooth, fluid, and pourable due to its high moisture content. Peanut butter is dense and paste-like with very little moisture.
  • Flavor – Maple syrup has a distinct maple taste. Peanut butter has an earthy, nutty peanut flavor.
  • Fat content – Peanut butter contains high amounts of fat from the nuts, while maple syrup contains no fat.
  • Calories – Maple syrup has about 200 calories per quarter cup. Peanut butter has about 200 calories per 2 tablespoons.

These differences make maple syrup and peanut butter non-interchangeable in most recipes. The moisture, sweetness, and flavor profile of maple syrup cannot be replicated by swapping in peanut butter. So generally peanut butter is not a suitable 1:1 substitute for maple syrup.

Substitution Potential

Even though peanut butter is not usually a direct substitute, it can sometimes be used in small amounts as part of a maple syrup replacement. Here are some tips for incorporating peanut butter:

  • Use just 1-2 tablespoons of peanut butter combined with sugar, water, and spices to mimic some sweetness and flavor of maple syrup.
  • Boost moisture and sweetness by mixing peanut butter with apple sauce, agave nectar, honey, or brown sugar.
  • Mix in a bit of maple extract or maple flavored syrup to help get a maple taste.
  • Focus on recipes where maple syrup is used in a supporting role rather than as the main flavor, such as cookies or bars.
  • Reduce the amount of peanut butter compared to the amount of maple syrup the recipe calls for.

Recipe Considerations

When deciding whether peanut butter can stand in for maple syrup, consider these factors about the recipe:

  • Amount of maple syrup – Small amounts needed for sweetening or flavor can be more easily replaced than large amounts where it provides moisture.
  • Other liquids – If the recipe already contains wet ingredients like eggs, milk, or fruit, you may not need to add as much moisture.
  • Flavor impact – Peanut butter has a stronger flavor so it will make more of an impact if maple syrup is a main flavor versus a background component.
  • Texture – Peanut butter may change the texture in baked goods, making them heavier or denser.
  • Sweetness level – You’ll need to boost sweetness from other sources if maple syrup is the main sweet element.

Test any maple syrup substitutions in small batches first to ensure the peanut butter achieves the intended moistness, sweetness, and flavor.

Baking Substitution

For baking, peanut butter can work best in cookies, bars, and some cakes and muffins, where small amounts of maple syrup are used. Try these tips:

  • Replace 1 tablespoon of maple syrup with 1 teaspoon peanut butter and a splash of water or milk.
  • Use brown sugar or honey for added moisture and sweetness.
  • Reduce peanut butter amounts compared to maple syrup in the original recipe.
  • Add a few drops of maple extract for flavor.
  • Skip peanut butter substitution in recipes where maple flavor is very prominent like maple baked oatmeal or maple cream pie.

Baking Substitution Examples

Pumpkin Maple Cookies

  • Original: 1/4 cup maple syrup
  • Substitute: 2 tbsp peanut butter + 2 tbsp brown sugar + 1 tbsp water + 1/4 tsp maple extract

Maple Walnut Muffins

  • Original: 3 tbsp maple syrup
  • Substitute: 1 tbsp peanut butter + 1 tbsp honey + 1 tbsp applesauce

Cooking Substitution

For cooking and sauces, it can be tricky to mimic maple syrup’s distinctive taste. But small amounts of peanut butter can replicate some texture and sweetness. Follow these guidelines:

  • Use just 1-2 tablespoons peanut butter in place of 1/4 to 1/3 cup maple syrup.
  • Combine with liquid sweeteners like honey, agave, or brown rice syrup.
  • Boost maple flavor with maple extract or maple syrup flavored sauce.
  • Stick to recipes where maple syrup is a background flavor, not the star.
  • Avoid using in recipes where maple syrup is a prominent flavor like maple glazes or maple salad dressings.

Cooking Substitution Examples

Maple Dijon Vinaigrette

  • Original: 1/4 cup maple syrup
  • Substitute: 1 tbsp peanut butter + 2 tbsp honey + 1 tbsp balsamic vinegar + 1/4 tsp maple extract

Maple Glazed Pork Chops

  • Original: 1/3 cup maple syrup
  • Substitute: 1 tbsp peanut butter + 3 tbsp brown rice syrup + 1 tsp maple extract

Snack Substitutions

Maple syrup is often used as a sweet topping or dip for snacks like fruit, waffles, yogurt, and oatmeal. For these uses, try mixing small amounts of peanut butter into creamy bases for texture and mild sweetness:

  • Plain Greek yogurt + 1 tbsp peanut butter + 1 tsp honey
  • Applesauce + 1 tbsp peanut butter + cinnamon
  • Cottage cheese + 1 tbsp peanut butter + dash of maple extract
  • Oatmeal + 1 tsp peanut butter + brown sugar + milk

You can also incorporate a bit of peanut butter into dips for pretzels or fruit without trying to mimic maple syrup’s exact taste.


One reason someone may want to substitute peanut butter for maple syrup is a preference for its nutrition profile. Here is how they compare:

Nutrition Fact Maple syrup (1/4 cup) Peanut butter (2 tbsp)
Calories 200 200
Fat 0g 16g
Saturated fat 0g 2g
Carbs 54g 7g
Sugar 52g 2g
Fiber 0g 2g
Protein 0g 8g

As shown above, peanut butter contains more protein and fiber. Maple syrup provides more carbs and sugar. Peanut butter has significantly more fat, including heart-healthy monounsaturated fats. So using peanut butter instead of maple syrup can increase nutrition in some recipes.

However, amounts would need to be carefully controlled, as peanut butter is high in calories. Maple syrup in moderation can have a place in a healthy diet. As with any substitution, pay attention to how it affects nutrition and adjust other ingredients accordingly.

Cost Comparison

Another reason to use peanut butter instead of maple syrup is cost savings. Pure maple syrup is collected seasonally and requires extensive processing, so it is one of the more expensive baking ingredients. Peanut butter made from conventionally grown peanuts is generally affordable.

Here is an approximate price comparison of maple syrup versus peanut butter:

  • Maple syrup: Approximately $0.75 to $1.00 per ounce
  • Peanut butter: Approximately $0.07 to $0.15 per ounce

With peanut butter priced around one-fifth to one-tenth the cost of maple syrup per ounce, it can lead to significant savings in recipes that use a lot of maple syrup. However keep in mind that to replace a quarter cup of maple syrup you would generally only use 1-2 tablespoons of peanut butter. So the actual savings may be small unless you use large volumes of maple syrup.

Taste Preference

Personal taste preferences may also lead someone to use peanut butter instead of maple syrup. While they are very different flavors, some people simply prefer the roasted, nutty taste of peanut butter over the woodsy sweetness of maple.

If you want to highlight the peanut flavor or avoid the strong maple taste, peanut butter can be an option. Just keep portions small and combine with other ingredients to try to mimic some of maple syrup’s moisture and sweetness.

You can also substitute peanut butter in treats like cookies or bars where the maple flavor is not as central. In baked goods with many competing flavors, the peanut taste may not seem as out of place.

Dietary Restrictions

People with certain dietary restrictions may need to replace maple syrup with peanut butter in recipes:

  • Sugar restrictions – People limiting sugar intake may want to avoid maple syrup’s high sugar content. Peanut butter has far less sugar.
  • Carb restrictions – For low-carb or keto diets, maple syrup contains over 50g carbs per quarter cup so should be limited. Peanut butter has far fewer carbs.
  • Vegan diet – Some strict vegans avoid maple syrup because of questions over whether tapping maple trees harms them. Peanut butter gives a plant-based alternative.
  • Allergies – Those allergic to tree nuts like walnuts may need to avoid maple products derived from maple trees. Peanut butter made from ground peanuts offers a replacement.

For people with these dietary needs, peanut butter can help remove maple syrup from recipes. Though again, the distinct flavors must be taken into account.

Environmental Sustainability

Some consumers choose peanut butter as a more environmentally sustainable choice compared to maple syrup:

  • Maple syrup production requires significant energy for collecting and boiling large amounts of sap. It also needs special equipment and forest management.
  • Peanut butter just needs land to grow peanuts and far less processing. This requires less overall resources.
  • Organic peanut production is easier and more scalable than organic maple syrup harvesting.
  • Peanuts can be grown year-round in many climates versus maple only growing in northeast North America.

So from a climate impact perspective, peanut butter may be viewed as a greener choice. But know that you would use far less peanut butter compared to the maple syrup it replaces.


Peanut butter is generally not the best direct substitute for maple syrup. Maple syrup provides a unique sweet flavor and moisture that peanut butter cannot fully replicate.

However, you can incorporate small amounts of peanut butter into recipes that call for maple syrup. Combine it with liquid sweeteners, spices, and extracts to try to mimic maple’s taste and texture. Focus on baked goods where maple syrup plays a secondary role.

The nutrition profile, taste, cost savings, and dietary restrictions may make peanut butter an appealing maple syrup alternative. But keep portions of peanut butter small since it has a very different flavor and fat content. Test any adapted recipes to ensure the substitution provides the moisture, sweetness, and flavor to successfully replace maple syrup.
