HALLOWEEN FRENCH MACARONS RECIPES

Steps:

• Preheat oven to 300°. Lightly grease two baking sheets with cooking spray and line with parchment.
• Make macarons: Set a fine-mesh sieve over a large bowl and sift 1 ¾ cup powdered sugar with almond flour. Use a rubber spatula to help push larger pieces through. Keep pressing until less than 2 tablespoons of solids remain. Discard solids.
• In a mixer, beat egg whites, cream of tartar, and a pinch of salt until frothy. Increase speed to medium-high and slowly add superfine sugar. Continue to beat on medium-high until egg whites are stiff and glossy, about 2 to 3 minutes.
• Beat in food coloring until combined, about 30 seconds more. Fold dry ingredients into beaten egg whites with a spatula until it flows like thick lava, about 2 minutes. 
• Fit a pastry bag with a a 1/4-inch round tip and transfer batter into bag. Dab some remaining batter in bowl onto the corners of two baking sheets and line sheets with parchment. Pipe batter into 1-inch circles, spacing each circle about 1 inch apart. Tap baking sheet against counter a few times to release any air bubbles. Let piped batter to sit out for 45 minutes before baking.
• Bake one sheet at a time, rotating halfway through, until risen and just set, 13 to 14. 
• Let cool 10 to 15 minutes before gently peeling parchment away to transfer to a rack to cool completely. 
• Using a mixer, beat butter with remaining ¾ cup powdered sugar and vanilla until fluffy and smooth. Pipe or spread filling on flat sides of half of cookies; top with remaining half. 
• Wrap in plastic and refrigerate until ready to serve.
