Bake Mini Champagne Orange Muffins (Mimosa Muffins) for a bright, bubbly brunch treat that's quick and festive.
Preheat the oven to 375°F and prepare one or two mini muffin pans by spraying them with floured cooking spray or greasing and dusting them with flour; set the pans aside to keep everything ready. Treat this like the quiet beginning — get the pans cozy and within reach so the batter will go straight in once mixed.
In a large bowl whisk together the all-purpose flour, baking powder, and salt until evenly distributed and aerated. Use a light, circular motion so the leavening is evenly spread and you have a smooth, pale flour base with no heavy pockets.
In a separate medium bowl whisk the granulated sugar, large egg, and oil until slightly emulsified, then stir in the orange zest, freshly squeezed orange juice, and the almond extract. The mixture should look glossy and fragrant — bright citrus specks suspended in a pale yellow base.
Whisk the champagne or prosecco into the wet mix until incorporated, then pour the wet into the dry bowl and fold gently using a spatula. Stir just until combined; the batter should be pale yellow with small lumps and visible orange zest flecks — slightly glossy from the oil and champagne, not smooth like cake batter. Avoid overmixing to keep the muffins tender.

Spoon or pipe the batter into the prepared mini muffin cavities about two-thirds to three-quarters full. Slide the pans into the preheated oven and bake for roughly 8 to 9 minutes, starting to check after 7 minutes; mini muffins rise and brown quickly. Look for pale golden tops that spring back when gently pressed.
Let the muffins cool in the pan for about 10 minutes so they settle and slightly contract from the pan edges. While they cool, prepare the glaze so it’s ready when the tops are just slightly warm — this timing helps the glaze adhere and set with a shiny finish.
In a medium bowl whisk confectioners’ sugar with champagne or prosecco until smooth and pourable; adjust liquid to reach a thick but dip-able consistency. Aim for a glossy, translucent glaze that will cling to the muffin tops without running off entirely — a delicate balance that preserves sparkle without becoming watery.
Dip each muffin top into the glaze, letting excess drip back into the bowl, then set the glazed muffins on a rack or plate for about 10 minutes until the glaze firms slightly. The finished muffins should be golden, bright with citrus zest, and capped with a glassy champagne glaze that catches the light.
