How Much Is 1/3 Cup Of Butter? The Ultimate Conversion Guide & Baking Secrets
Ever found yourself staring at a recipe that calls for 1/3 cup of butter, only to realize your measuring cups are in the dishwasher? You’re not alone. This common measurement can throw off your entire bake if guessed incorrectly. In this article, we will provide you with the precise conversion of 1/3 cup of butter into tablespoons and address other frequently asked questions related to butter measurements. Whether you're a novice baker or a seasoned chef, understanding these conversions is non-negotiable for consistent results.
Butter is the soul of countless recipes, from flaky pastries to rich sauces. Its fat content, water percentage, and temperature dramatically affect texture and flavor. Getting the measurement wrong can mean the difference between a perfectly chewy cookie and a dry, crumbly disaster. This guide provides everything you need to know to accurately measure butter for baking and cooking, transforming uncertainty into confidence in your kitchen.
The Core Conversion: What is 1/3 Cup of Butter in Tablespoons?
Let's cut to the chase. How much is one third of a cup in tablespoons? The answer is straightforward but crucial.
1/3 cup of butter is equal to 5 1/3 tablespoons, or approximately 2.67 ounces (by weight).
This simple calculator will allow you to easily convert ⅓ cp to tbsp. But what does "5 1/3 tablespoons" mean in practical terms? It’s 5 full tablespoons plus 1 teaspoon. Since 1 tablespoon equals 3 teaspoons, 1/3 of a tablespoon is exactly 1 teaspoon.
Key Takeaway:⅓ cup of butter = 5 tablespoons + 1 teaspoon.
If you don’t have a ⅓ cup measure handy, or you’re slicing butter from a stick, you’ll just need to know this combo. In the U.S., 1 stick of butter = 8 tablespoons = 24 teaspoons. Therefore, 1/3 cup (5⅓ tbsp) is just over half a stick of butter (which would be 4 tbsp). This is the most common point of confusion, so let's clarify it once and for all.
Visualizing the Measurement
Imagine your standard stick of butter, usually marked with tablespoon lines. To get 1/3 cup:
- Slice the butter at the 4-tablespoon (½ stick) line.
- Then, add one more full tablespoon on top.
- Finally, add one teaspoon.
For the most precision, using a kitchen scale is the gold standard. Weighing 2.67 ounces (or about 75.6 grams) eliminates all guesswork and is the professional baker's secret weapon.

The "Why" Behind Butter's Behavior in Baking
It’s not enough to just measure; you must understand why. Learn how butter measurements really behave in cooking and baking. The physical state of your butter—its temperature—is as important as the quantity.
- Cold Butter (Firm, straight from fridge): Essential for pastries, pie crusts, and scones. You want cold, solid butter cubes that create steam pockets during baking, leading to flaky layers. If it’s too warm, it melts and creates a dense result.
- Room Temperature Butter (Soft, ~65-70°F / 18-21°C): The standard for creaming with sugar in cakes and cookies. Properly softened butter traps air when beaten with sugar, creating a light, aerated structure. "Slightly softened" is somewhere between straight out of the refrigerator and room temperature—it should indent slightly with a gentle press but not be greasy or melty.
- Melted Butter: Used for quick breads, brownies, and some cookies. It yields a denser, fudgier texture because it doesn't trap air. The difference between good and great chocolate chip cookies comes down to one ingredient technique: many chefs swear by using melted butter and an extra egg yolk to create that coveted thick, chewy texture that stays soft for days.
Pro Tip: If a recipe says "softened butter," don't microwave it! Cut it into small cubes and let it sit for 20-30 minutes. Microwaving creates uneven hot spots that melt parts of the butter, ruining your creaming process.
Practical Application: Recipes Using 1/3 Cup of Butter
Knowing the conversion is useless without application. Here are common scenarios where you’ll need exactly 1/3 cup (5 tbsp + 1 tsp) of butter.
1. Classic Shortbread or Sugar Cookies
Many shortbread recipes use a 1:2:3 ratio (sugar:butter:flour by weight). For a small batch, you might use 1/3 cup (2.67 oz) butter, 5.33 oz sugar, and 8 oz flour. The precise butter amount ensures the perfect sandy, tender crumb.
2. Frostings and Glazes
A standard American buttercream uses a 1:2 ratio of butter to powdered sugar (by volume). For a small batch, 1/3 cup of butter would require about 2/3 cup of sifted powdered sugar, plus flavorings. I only ever use real butter, but you can use whatever you have on hand. Although I think margarine changes the taste, your buttercream frosting made with margarine will still be better than canned frosting—but for best flavor and structure, real unsalted butter is non-negotiable.
3. Sauces and Finishing Butters
Compound butters (like garlic herb butter) or simple pan sauces often start with a specific butter amount. 1/3 cup is perfect for a sauce for 2-3 servings. Remember to add it off the heat to prevent separation.
A Deeper Dive: Recipe Examples from Our Key Sentences
Let's connect the dots from our source material into usable knowledge.
Golden Coconut Kingston Sandwich Biscuits
Ingredients:
- 1 cup unsalted butter, softened
- 3/4 cup brown sugar
- 1/4 cup granulated sugar (implied)
- 3 cups almond flour (or all-purpose)
- 3 eggs
- 1 cup of sugar (additional or total)
- 1/4 cup neutral oil (like coconut or vegetable)
- 1/4 cup water
- 1 teaspoon baking soda
- 1 teaspoon baking powder
- 1 teaspoon vanilla powder or vanilla extract
Method:Preheat oven to 350°F (175°C). Add all ingredients to a food processor and blend until a smooth, thick batter forms. Bake for 22 to 25 minutes on a well-oiled tin or parchment-lined sheet until golden. Cool completely before sandwiching with cream filling.
Note: The recipe lists 1 cup of sugar twice? This is likely a typo in the source. Typically, it's 3/4 cup brown sugar + 1/4 cup white sugar, totaling 1 cup. The oil and water might seem odd for a biscuit—this suggests a more cake-like or egg-rich "biscuit" (cookie) texture, common in some global recipes.
Irresistible Banana Bread Cinnamon Rolls
While the full recipe isn't detailed, the principle is the same. A rich, soft dough for cinnamon rolls relies on a tender crumb from properly measured fat. 1/3 cup of butter in the dough portion would contribute significantly to that soft, pull-apart texture.
Reese's-Inspired Peanut Butter Chocolate Chip Cookies
Ingredients:
- 1 cup chocolate chips
- 1/2 cup creamy peanut butter
- 1/4 cup butter (This is exactly 4 tbsp, or 1/4 cup)
- 1/2 cup powdered sugar
- 1 (8.8 ounce) box Ritz Bits (or similar cracker cookies)
Method:
- Line a baking sheet with parchment paper.
- Combine chocolate chips, peanut butter, and butter in a saucepan over low heat.

Your Ultimate Muffin Blueprint
Understanding butter measurement is put to the test in a foundational recipe like muffins. This is my ultimate muffin recipe—starting with a thick and creamy muffin batter, your choice of additions, and two topping options.
A basic muffin batter ratio is roughly: 2 parts flour : 2 parts liquid : 1 part egg : 1 part fat (butter/oil). For a recipe yielding 12 muffins, you might use 1 cup (2 sticks) of butter. If scaling down to 4 muffins, you’d need 1/3 cup (5 tbsp + 1 tsp) of butter.
Why the fat matters: Butter provides flavor and a tender crumb. Oil (like the 1/4 cup in the Kingston biscuit recipe) provides extreme moistness and density. The choice defines your muffin's texture.
Frequently Asked Questions (FAQs)
We’ve got the answer, and it’s super simple. Here are the most common butter measurement queries:
Q: Can I use margarine instead of butter?
A: Technically yes, but margarine changes the taste and has a different water-fat ratio, which can affect texture (spreading more, less crispness). For best results in baking, use real butter. For frying or some cookies, a high-quality margarine can be a substitute.
Q: How do I measure butter without a scale?
A: Use the conversion chart! For 1/3 cup, use 5 tbsp + 1 tsp. For sticks, remember the lines. If your butter isn't in stick form, press it firmly into a dry measuring cup.
Q: What is "slightly softened" butter?
A: It’s not warm or greasy. It should be pliable but still hold a slight shape. Press your finger into it—it should make an indent that holds. This is perfect for creaming.
Q: Does salted vs. unsalted butter change the measurement?
A: No, the volume/weight is identical. The difference is salt content. Most baking recipes specify unsalted butter so you can control the salt level. If using salted, you may need to reduce any added salt slightly.
Q: My butter is too soft! What do I do?
A: Place it back in the fridge for 10-15 minutes. You can also chill your mixing bowl and beaters before creaming to keep the butter cooler longer.
