Strawberry Buttercream Frosted Donuts

The smell of strawberries and buttercream always pulls me straight back to a rainy Saturday when my niece appeared in the kitchen doorway, flour dusted across her nose, demanding pink donuts for her birthday party instead of cake.

I piped all twelve donuts that afternoon while my niece sat on the counter handing me strawberries and eating every third one she was supposed to garnish with.

Ingredients

• All-purpose flour (2 cups, 250 g): Gives the donuts their soft, cakey crumb without making them dense or heavy.
• Granulated sugar (2/3 cup, 135 g): Just enough sweetness in the base so the frosting can shine without overwhelming the whole bite.
• Baking powder (2 tsp): The leavening workhorse here since these are baked, not fried, so they need that lift to stay fluffy.
• Salt (1/2 tsp): A small amount that rounds out the sweetness and wakes up every other flavor in the batter.
• Whole milk (2/3 cup, 160 ml): The fat content matters for moisture and tenderness, so avoid swapping to skim if you can help it.
• Large eggs, room temperature (2): Room temp eggs blend more evenly into the batter, which means fewer lumps and a smoother donut.
• Unsalted butter, melted (1/4 cup, 60 g): Adds richness and a subtle buttery flavor that pairs beautifully with the berry frosting on top.
• Vanilla extract (1 1/2 tsp): Use the real stuff, not imitation, because it forms the warm background note tying everything together.
• Unsalted butter, room temperature (1/2 cup, 115 g) for frosting: This is the backbone of your buttercream, so pull it out an hour ahead and let it soften naturally.
• Powdered sugar, sifted (2 cups, 240 g): Sifting is nonnegotiable here unless you want gritty little sugar lumps in your silky frosting.
• Strawberry puree (1/4 cup, 60 g): Blend fresh or thawed frozen strawberries until perfectly smooth for the most vibrant, honest berry flavor.
• Vanilla extract (1/2 tsp) for frosting: A lighter hand than the batter because you want the strawberry to be the star of the show.
• Salt (pinch) for frosting: This tiny addition balances the sweetness and makes the strawberry taste more like itself.
• Fresh strawberries and sprinkles (optional garnish): Thinly sliced berries look stunning, and sprinkles make them party ready in seconds.

Instructions

Get your oven ready:

Preheat to 350 degrees F (175 degrees C) and generously grease two 6 cavity donut pans with butter or nonstick spray so nothing sticks later.

Build the dry mixture:

In a large bowl, whisk together the flour, sugar, baking powder, and salt until evenly distributed and free of any flour pockets.

Combine the wet ingredients:

In a separate bowl, whisk the milk, eggs, melted butter, and vanilla until smooth and cohesive, with no streaks of egg yolk visible.

Marry the two:

Pour the wet into the dry and fold gently with a spatula until just combined, stopping the moment you no longer see dry flour streaks.

Fill the pans:

Spoon the batter into each cavity to about three quarters full, using a steady hand to keep the center hole clean and open.

Bake until golden:

Bake for 10 to 12 minutes until a toothpick inserted comes out clean and the tops spring back gently when lightly pressed with your fingertip.

Cool properly:

Let them rest in the pans for 5 minutes, then carefully transfer to a wire rack to cool completely before any frosting touches them.

Whip the buttercream:

Beat the softened butter until creamy and pale, then gradually add the sifted powdered sugar, beating until the mixture turns light and fluffy.

Add the strawberry magic:

Beat in the strawberry puree, vanilla, and that pinch of salt for 2 to 3 minutes until the frosting is smooth, pink, and spreadably soft.

Frost and garnish:

Spread or pipe the buttercream onto completely cooled donuts, then top with sliced strawberries or sprinkles if you are feeling festive.

By the time the last donut was frosted, my niece had strawberry puree on her chin and the biggest grin I have ever seen on a seven year old.

Keeping Your Donuts Fresh

Store these in an airtight container at room temperature for up to two days, though honestly they rarely last that long in my house.

Freezing for Later

You can freeze the unfrosted donuts for up to three months by wrapping each one tightly in plastic wrap and tucking them into a freezer bag.

Making Them Your Own

This recipe is endlessly adaptable once you master the base donut and buttercream technique.

• Swap the strawberry puree for raspberry or mango to create entirely new flavor profiles.
• Add a teaspoon of freeze-dried strawberry powder to the frosting for an intense berry punch without extra moisture.
• Always taste your buttercream before piping, because strawberry sweetness varies wildly depending on the season and the fruit you start with.

These donuts are pure joy on a plate, and watching someone bite into one for the first time is reason enough to make them again and again.

Recipe FAQs

→ Can I use frozen strawberries for the buttercream frosting?

Yes, frozen strawberries work perfectly. Thaw them completely, then blend into a smooth puree. Drain any excess liquid before adding to the buttercream to prevent it from becoming too soft or runny.

→ Why are my baked donuts dense instead of fluffy?

Overmixing the batter is the most common cause. Stir wet and dry ingredients together only until just combined a few lumps are fine. Also ensure your baking powder is fresh and active for proper rise.

→ Do I need a donut pan to make these?

A donut pan gives the classic shape, but you can use a muffin tin as an alternative. Fill each cup about half full and reduce baking time slightly. The texture and flavor will remain the same.

→ How should I store leftover frosted donuts?

Store them in an airtight container in the refrigerator for up to 3 days. Let them sit at room temperature for about 15 minutes before serving so the buttercream softens and the donut regains its tender texture.

→ Can I make the strawberry buttercream ahead of time?

Absolutely. Prepare the buttercream up to 3 days in advance and refrigerate it in an airtight container. When ready to use, let it come to room temperature and re-whip with a mixer until smooth and fluffy again.

→ How can I intensify the strawberry flavor in the frosting?

Add 1 to 2 teaspoons of freeze-dried strawberry powder to the buttercream for a concentrated burst of strawberry flavor without adding extra moisture. This also enhances the natural pink color beautifully.
